G4-DMA: Respect for the natural environment is paramount and essential to the sustainability of our business. From our potash mines in Saskatchewan to our Florida phosphate operations and blending facilities in Brazil, we strive to optimize our production processes and reduce our environmental footprint.

At Mosaic, we believe lasting success comes from making smart choices about how we manage resources. We are committing significant resources to advancing our efforts in water conservation, land reclamation and waste reduction, and producing clean energy through cogeneration in our phosphates operations. We are also committed to the responsible and sustainable use of our products. By promoting and advancing 4R Nutrient Stewardship, we are working to mitigate potentially negative environmental impacts stemming from improper use of fertilizer.

This year, we have developed sustainability targets to help focus our efforts and track our progress in the areas of water, energy, greenhouse gases and waste. We are committed to achieving these targets and will work to evaluate future areas for measurement and improvement.

Managing Our Water Footprint

Responsible use of water is a fundamental component of Mosaic’s global sustainability vision. Our water management programs involve facility- specific and business unit-wide initiatives to reduce our water footprint.

Water Withdrawals

(G4-EN8) The primary sources of water for our operations are surface water, rainwater and groundwater. Secondary sources of water include water supplied by local authorities and partially treated industrial and domestic reclaimed water, also supplied by local authorities. Surface water withdrawals include once- through cooling water used by operations in Louisiana.

Mosaic operations capture rainfall, a portion of which is impounded and used in the various production processes, with some discharged through permitted outfalls. Traditionally, Mosaic has considered captured rainfall use as an “alternative water supply.” Captured rainfall is used in part to estimate recycle/reuse water usage rates at Florida concentrate and minerals operations.

Total 288,717 268,763 288,274 319,004 309,370

In alignment with our Sustainability Targets, we have modified our water intensity reporting to reflect a freshwater intensity measurement. In setting a water target, our intent is to drive water efficiency improvements across our business and to increase the use of alternative sources.

Mosaic’s freshwater withdrawals per tonne of dry product crop nutrient and animal feed production are as follows:

Freshwater Intensity

2010 2011 2012 2013 2014
Mosaic 4.38 4.37 5.43 5.07 4.59

Notes: "Intensity" refers to the volume of water used in making product (m3) per unit of product manufactured (metric tonnes). Production includes all crop nutrients and animal feed ingredients produced in the calendar year. "Freshwater" is defined as groundwater and surface water and excludes reclaimed water, brine, seawater and Mississippi River water used for once-through cooling.

For withdrawals and total intensity broken down by business unit, please see our Environment Metrics Supplement page.

(G4-EN9) Mosaic’s Central Florida fertilizer production facilities operate on more than 90% recycled or reused water. Deep well pumping from the Floridan Aquifer is strictly regulated, and is used as a supplemental water supply on an as-needed basis. Local regulations favor the use of available alternative water supplies, such as reclaimed water from municipalities, before groundwater use. Mosaic Florida sites received reclaimed water from six municipal waste water treatment plants in 2014 at an average rate of 2.1 million gallons per day (MGD). Please see G4-EN8 and G4-EN10 for additional context.

Once water use permits are issued, permit holders must regularly evaluate and report to the Southwest Florida Water Management District on water conservation efforts to minimize groundwater use for processing needs on an annual basis. To demonstrate the substantial results achieved through water conservation efforts over time, in 1991, Mosaic’s predecessors used approximately 1,000 gallons of water to process one ton of phosphate rock; currently the water use has been reduced by approximately 50% to about 500 gallons of water per ton of phosphate rock. Mosaic’s water use permit also reflects this decrease in demand. In fact, the Integrated Water Use Permit was renewed in 2012 with an annual average permitted quantity of 69 MGD versus the previous permit for the same area authorizing water use of 99 MGD, representing a reduction of 30%.

In the Phosphates Business Unit, to avoid any impacts on adjacent wetlands and other surface water sources, active mining areas are surrounded by a protective recharge ditch and berm system that assists in maintaining the groundwater table elevation. The Phosphates Business Unit does not withdraw water from rivers or lakes to supplement freshwater needs, further protecting ecological resources from undue stress.

The final Areawide Environmental Impact Statement (AEIS), a two-plus-year study released by the U.S. Army Corps of Engineers (ACOE) in April 2013 and addended in July 2013, evaluating the cumulative impacts of phosphate rock mining in Central Florida, concluded that the effects from mining on groundwater resources would be “minor” in magnitude and not “significant.” A similar conclusion was reached for surface water resources in the July 2013 AEIS Addendum, which also indicates that surface water and ecological impacts would be “minor” and with mitigation would not be significant.

Water Recycling

(G4-EN10) Our facilities continuously monitor and evaluate water use to ensure it is minimized, and water recycling and reuse are maximized. Recycle and reuse percentage rates for Mosaic’s Potash and Phosphate Business Units are presented here. Rates and volume are based on total water used by facility, less freshwater withdrawals.

Phosphates 672,712 90%

Notes: Carlsbad, N.M., South Pasture, Plant City, and South Pierce, Fla., and Faustina and Uncle Sam, La., are not included in respective business unit calculations. Belle Plaine is a solution mine and therefore, water use and methodology for recycle/reuse rate differs from shaft mining operations. Mosaic operations capture rainfall, a portion of which is impounded and used in the various production processes, with some discharged through permitted outfalls at Phosphates facilities. Traditionally, Mosaic has considered captured rainfall use as an alternative water supply, and it is used in part to estimate recycle/reuse water usage rates at Florida concentrate and minerals operations.

Effluents & Waste

Water Discharges

(G4-EN22) Discharges from Mosaic’s U.S. phosphate operations to nearby water bodies are highly regulated through federal National Pollutant Discharge Elimination System (NPDES) permits (administered by FDEP), which require ongoing demonstration of compliance with effluent limitations. These limitations are based on the water quality standards that protect the designated uses of the receiving water body. As an overarching principle, water that falls within the active, operational footprint at Mosaic’s phosphate mining and fertilizer production facilities is actively managed, treated if necessary and discharged only through outfalls, whose locations are permitted through the NPDES program. Discharges are monitored, sampled and analyzed regularly by Mosaic, and reported to the regulatory agencies to demonstrate ongoing compliance with these permit limitations. By maintaining compliance with all NPDES permits, Mosaic ensures that its discharges meet existing regulations.

In 2014, Mosaic’s Canadian Potash facilities helped preserve water quality off-site by maintaining a zero-discharge approach, with the capture of surface water runoff from the sites. In certain circumstances of high precipitation events, off-site discharges of freshwater surface runoff are warranted and are approved in advance by the Saskatchewan Ministry of Environment. There were two such instances in 2014.

A significant percentage of the total outfall discharge from Florida Phosphate operations is from rainwater. The discharge pattern tends to follow the rainfall pattern (e.g., more discharges occurring immediately following rainfall events) and the total can vary year to year depending on the levels of precipitation. In Florida, our operations are located in the following river basins: Alafia River, Hillsborough River, Little Manatee River, Myakka River and Peace River, with one fertilizer manufacturing facility’s outfalls directing water to Tampa Bay. Mosaic’s Phosphates facilities in Louisiana have permitted outfalls that discharge water to the Mississippi River. The following table summarizes the total surface water discharge from our Phosphate operations in Florida and Louisiana combined. As of the date of this publication’s release, 2014 discharge data is not available. We expect to publish 2014 data here after July 2015.

Water Discharges are:

sampled and analyzed regularly
reported to regulatory agencies
compliant with existing regulations

(G4-EN26) The discharge of water and runoff from Mosaic’s mining and fertilizer manufacturing is a highly regulated activity that has stringent reporting and compliance requirements. The release of water via storm water or discharge must comply with these requirements. The standards enforced by the regulatory authorities are designed to protect water bodies and associated habitats from degradation and secondary environmental impacts. None of the points of discharge releases water directly into a designated protected area.

The five riverine basins in which Mosaic operates in Florida include the Hillsborough, Peace, Alafia, Little Manatee and the Myakka Rivers. These riverine systems vary in size, as indicated below.

Florida Riverine Basins Where Mosaic Operates

Water Body/Basin Basin Size
River Length
Hillsborough River 175,000 95
Peace River 608,000 169
Alafia River 109,000 38
Little Manatee River 58,000 58
Myakka River 155,000 106

Water discharge examples at our major facilities:

  • Any releases are subject to water constituent limitations designed to be protective of downstream biological communities. This water quality protection is particularly important as segments of the Little Manatee River and the Myakka River, downstream of Mosaic’s operations, are designated as Outstanding Florida Waters—with a portion of the Myakka River also being classified as a Florida Wild and Scenic River. The final AEIS released by the ACOE in April 2013 and supplemented in July 2013, which documented the findings of a comprehensive two-plus-year study on the direct, indirect and cumulative impacts of proposed and reasonably foreseeable phosphate mining projects in the Central Florida Phosphate District, concludes that the effects of mining will not have a significant water quality impact, in part, because the proposed projects are not expected to cause violations of water quality standards. While acknowledging that NPDES-permitted discharges associated with the proposed mine alternatives may add some authorized quantities of certain regulated or targeted constituents to receiving waters, the final AEIS concluded that anticipated, resulting levels of these parameters would not constitute a health risk nor present an unacceptable risk to stream biota.
  • In Louisiana, our Faustina and Uncle Sam plants intake and outfall to the Mississippi River. This process is highly regulated by the state to ensure that gross contaminant levels are acceptable.
  • For our Canadian Potash operations, we have no off-site releases of water or runoff as part of normal operations. See G4-EN22 for additional context.

Reducing Our Energy Use & Emissions

Since our company’s formation in 2004, Mosaic has invested in site- specific initiatives and companywide programs aimed at reducing energy use and emissions. These efforts are resulting in operating cost savings and improvements in environmental performance.


(G4-EN3) Mosaic’s worldwide total direct energy consumption in 2014 was 95.43 million gigajoules (GJ).

Energy Consumption by Source

Approximately 92% of Mosaic’s worldwide total direct energy consumption in 2014 was from two sources: waste heat from sulfuric acid production and natural gas. The remaining portion was made up of petroleum products and propane.

Our Phosphate operations require the production and consumption of sulfuric acid to liberate crop nutrients (phosphorous) from raw material inputs. The manufacture of sulfuric acid is an exothermic process, generating tremendous amounts of waste heat. Most of our finished phosphate crop nutrient manufacturing operations have installed bottoming cycle combined heat and power systems to convert this waste heat primarily into steam, used in the phosphate manufacturing facilities and mines.

total direct energy consumption by source chart

In 2014, our Phosphate operations used a portion of this energy to produce 5.8 million GJ of electricity, approximately 90% of which was used internally. We consider the waste heat from sulfuric acid production to be a direct primary energy source for our operations. Mosaic exported approximately 700,000 GJ of power to the local utility grid in 2014.

Natural gas is primarily used in our Phosphate and Potash operations to generate thermal energy for drying. However, a small portion of this fuel is used to produce steam for internal combined heat and power generation.

Energy Consumption by Business Unit

Almost all of Mosaic’s worldwide total direct energy consumption is attributable to its phosphate and potash crop nutrient manufacturing operations. Specifically, approximately 79% is consumed in the production of phosphate crop nutrients while almost 20% is consumed in production of potash. The remaining portion—less than 1%—is consumed within Mosaic’s product distribution network and international production facilities.

mosaic energy consumption by business segment 2014
5,8 million GJ of electricity produced by our phosphate operations in 2014 90% used internally

Indirect Energy Consumption by Business Unit

Mosaic consumes indirect energy solely through the purchase of electricity produced by third parties. Mosaic’s worldwide indirect energy consumption was 10.48 million GJ for 2014. This is an increase over 2013 levels, due primarily to our acquisition in 2014.

Indirect Energy Consumption by Business Unit chart

Indirect Energy Consumption by Fuel Source

Approximately 12% of Mosaic’s worldwide indirect energy consumption is from renewable sources, including hydroelectric, biomass sources and wind power. Since 2009, almost 100% of the electricity used in our Brazilian operations has come from hydroelectric sources.

turbo generator

Our new turbo generator at New Wales adds 35 megawatts of GHG emissions-free electrical generation capacity

As previously noted, Mosaic’s Phosphate operations produce a significant amount of electrical power through steam turbine generation from waste heat generated in sulfuric acid production. Phosphate crop nutrient manufacture requires the production and consumption of sulfuric acid to liberate crop nutrients (phosphorous) from raw material inputs. In 2014, Mosaic’s Phosphate operations produced 5.8 million GJ of electricity through this process. Of this 5.8 million GJ, Mosaic consumed approximately 5.1 million GJ internally, offsetting the purchase of electricity from third-party utilities.

Mosaic continuously looks for opportunities to improve the efficiency of, and expand the electricity output of, our cogeneration assets. In 2014, Mosaic began operation of a new turbo generator (TG) at our New Wales facility. This investment adds 35 megawatts of greenhouse gas (GHG) emissions-free electrical generation capacity using heat recovered from sulfuric acid manufacturing.

Energy Consumed Outside the Organization

(G4-EN4) Mosaic has engaged upstream and downstream stakeholders in our supply chain to better quantify the impacts of our business. We report GHG emissions associated with various sources in G4-EN17 and continue to collaborate with vendors and contractors to quantify the amount of energy consumed outside the organization. We anticipate expanding the scope of our reporting for this indicator in the near future.

Energy Intensity

(G4-EN5) Mosaic’s three-pronged approach of energy management through cogeneration, conservation and greater efficiency aims to lead the industry in reducing the energy we use and maximizing the clean energy we generate. We are committed to evaluating alternative energy sources to satisfy our energy requirements. By 2020 we aim to reduce our total energy use by 10% per tonne of product.

Mosaic's three-pronged approach to energy management:

close-up of employee in PPE

A portion of the electricity required in Mosaic’s operations is satisfied through internal generation of electricity. This process of waste heat recovery, called cogeneration, allows several of our plants and mines to significantly reduce the amount of third-party electricity required from utilities. In October 2005, the Florida state legislature formally recognized that cogenerated electricity is “renewable energy” under Florida statute 366.91. In 2014, Mosaic produced enough electricity in all business units—approximately 6.97 million GJ through cogeneration—to satisfy approximately 38% of our companywide electrical demand. Over 800,000 GJ of this cogenerated electricity was sent for use at our mines.

Mosaic could have additional opportunities for harnessing emissions-free power under a more supportive regulatory construct. We advocate for a balanced renewable energy policy that incentivizes and expands the generation and consumption of existing, low-cost renewables, such as waste heat recovery, and promotes fairer pricing for third-party renewable producers when selling power back to the electrical grid.

Reducing Our Energy Consumption

(G4-EN6) Our continuous energy improvement and sustainability process is part of a broader strategic business plan designed to help Mosaic meet or exceed production and profitability requirements. This plan includes strategies for lowering purchased energy consumption through more efficient processes and maximizing use of energy generated through the crop nutrient manufacturing process.

To identify and capture potential energy opportunities, we have formed teams of energy representatives at our sites. These teams investigate a number of issues, such as improvements in natural gas use (e.g., efficiencies in boilers, dryers, mine air heating and cogeneration) and improvements in electrical systems (e.g., efficiencies in cogeneration systems and slurry pumping, including extensive use of variable speed drives, air compression, and heating and lighting systems). We also pursue energy savings by improving equipment use efficiency. For example, in 2014, operating crews at our Florida mining facilities initiated an energy conservation contest—a friendly competition across shifts and locations to see which crew runs its shift using the least amount of energy. Before the start of each shift, crews use a performance scorecard to communicate energy saving successes and opportunities for improvement. The winning crews are awarded with a meal at the end of the contest.

In addition, Mosaic regularly conducts energy reviews to help identify potential efficiency projects and assess major manufacturing processes such as combustion, general electrical, electric motor systems, compressed air systems and heating. We also have engineers assigned to individual facilities to help identify and execute energy efficiency initiatives. Projects are monitored and audited, and the resulting metrics are used to establish key performance indicators. These efforts reduce Mosaic’s overall energy profile, operational costs and use of indirect natural resources.

Mosaic also emphasizes energy efficiency in our office facilities. Mosaic’s Florida corporate headquarters maintains its ENERGY STAR certification. Mosaic’s leased Regina, Canada, offices were built to Leadership in Energy & Environmental Design (LEED) standards and included the purchase of interior design elements, furniture and products, as well as other energy efficiencies associated with LEED. Similarly, Mosaic’s Colonsay Mill Dry building in Saskatchewan was designed and constructed according to LEED standards. The LEED certification process for both buildings is underway.

We forecast savings of approximately 1.6 million GJ due to conservation and efficiency improvement projects that were executed in 2014. Several examples of energy efficiency efforts by our operations are outlined below.

(G4-EN7) Innovation is one of Mosaic’s strategic priorities. Built on our industry-leading product, process and sustainability solutions, it shapes our long-term strategy as we seek to reduce energy use and GHG emissions while delivering unique value to our stakeholders. Mosaic has a vested interest in the success of our customers, for it is their efforts that provide the food that feeds the world. To this end, Mosaic has developed several products and services that enhance customers’ productivity and positively impact their energy efficiency.

For example, in 2014, Mosaic continued full-scale production of Nexfos®, the next generation feed-grade phosphate that is characterized as being a combined source of highly available phosphorous, calcium and sodium. Not only is Nexfos the first innovation in feed-grade phosphate in over 40 years, the product is helping Mosaic meet its commitment to sustainability by reducing its environmental footprint. The Nexfos production process has significantly reduced the carbon footprint associated with the production of comparable feed phosphates by requiring approximately 60% less water, 70% less natural gas and 55% less electricity per ton to produce. It also reduces purchasing, storing and handling costs for consumers.

In addition, Mosaic maintains active partnerships with industry-leading research centers, targeting agriculture efficiency and productivity improvements. For more information on our partnerships, please see G4-EN27.

In 2014, energy efficient or renewable energy based initiatives resulted in approximately 550,000 GJ of energy savings. Please refer to the table in G4-EN6 for additional information on our efforts to provide energy efficient or renewable energy based products or services.

Note: Emissions intensity refers to total CO2e emissions generated in metric tonnes per unit of product measured in metric tonnes. Excludes co-products. Includes all Scope 1 and Scope 2 emissions sources reported in previous GRI/CDP.

(G4-EN19) Mosaic is taking a proactive approach to reductions in emissions, with particular emphasis on improving energy efficiency and waste management. Since 2005, we improved the Phosphates Business Unit’s GHG emissions intensity by 14.5%—surpassing our 2012 goal by nearly 45%. By 2020, we aim to reduce our Scope 1 and Scope 2 GHGs by 10% per tonne of product.

GHG emission reductions resulting from the initiatives reported in G4-EN6 equal approximately 400,000 tonnes of CO2e.

For more information on Mosaic’s efforts to reduce GHG emissions and address climate change, please see our 2014 CDP Response.

Other Emissions

(G4-EN20) Mosaic does not produce CFCs, HCFCs, halon or methyl bromide in any of our operations. Refrigerants used in air conditioning units at our offices and production facilities represent a nominal quantity and only appropriate outside firms or certified internal technicians maintain these units. Air conditioning systems on some vehicles and equipment are maintained by Mosaic personnel. Ozone-depleting substances are phased out as required when units are replaced. In 2012, Mosaic inventoried refrigeration units in over half of its worldwide facilities for potential emissions related to global warming potential and ozone depleting potential (OZP). Mosaic has targeted the remaining facilities, including acquisitions, to be inventoried in 2015. Potential GHGs from refrigerants, expressed in CO2e, are included in G4-EN16.

(G4-EN21) Mosaic recognizes the importance of careful air emissions management and proactive reduction of these emissions from our operations. We use published emission factors and engineering estimates, as well as analytical stack sampling results, to calculate the following criteria air and other pollutants emissions for Phosphates and Potash operations. Due to regulatory reporting timelines, 2014’s data was unavailable at the time of this publication’s release; we expect to publish 2014 data here after June 2015.

In any given year, Mosaic moves upwards of 60 million tons of raw materials, work-in-progress goods and finished products. We strive to transport materials as efficiently as possible, both in terms of cost and environmental impact.

(G4-DMA) In 2014, we engaged 14 external supply chain providers to attempt to better understand the emissions impact associated with upstream and downstream transportation. We continue to evaluate additional sources of emissions and anticipate expanding the scope of our reporting in the future to include additional sources. Please see G4-EN17 for more information.

(G4-EN30) To compare fuel efficiency, the industry standard is to measure ton-miles per gallon (ton/miles/gallon). The following chart compares the efficiency of the various modes of transportation that Mosaic uses to move our raw materials, work-in-progress and finished goods. The most fuel efficient transport is by Panamax vessels, which carry more than 60,000 tons of cargo great distances. In North America, cross-Gulf barges and vessels move raw materials and finished goods across the Gulf of Mexico quite efficiently. Trucks can carry approximately 25 tons and yield approximately 155 tons/miles/gallon.

For 2014, our spending on North American transport of materials and products was divided across modes as follows:

The following table summarizes the amount of material transported and percentage by weight for North American shipments.

Transport Mode and Weight

Vessels and Cross Gulf 16,258,729 26%
River Barge 4,511,069 7%
Rail (Cars) 28,762,231 46%
Truck 13,265,064 21%
Total 62,797,093 100%

Note: This table includes shipments of raw materials and finished product from origin to final destination that originated or ended in North America.

Mosaic and its transportation partners use fuel and GHG emission-saving initiatives:

Establishing partnerships with vendors to increase efficiencies and reduce cost

Chartering the most efficient vessels available

Investing in faster truck loading processes

Using specialized Saddleback trailers to increase backhaul usage to reduce "dead head"

Energy Use and Emissions Associated with Transportation

Because diesel or a heating oil derivative fuels most of the transportation, the lowest-cost option for the customer is often the option that uses the least fuel and has the lowest potential environmental impact. The vast majority of our truck shipments occur within Florida and are associated with time-sensitive intra-company shipments of sulfur, sulfuric acid and phosphate rock. In addition, the distance traveled in most cases is less than 50 miles, making trucks a generally less expensive and more reliable solution.

Environmental impacts of transporting our materials are primarily related to GHG emissions. During the 2014 reporting period, Mosaic and its transportation partners used various fuel and GHG emission-saving initiatives, including:

  • Mosaic continued our participation with the PhosPro Initiative to improve our handling of raw materials that travel by rail. Consisting of cross-functional teams at Mosaic and CSX, the PhosPro initiative focuses on increasing efficiencies and reducing costs for both companies. Mosaic anticipates benefits such as moving more finished products upstream by rail instead of truck, which will result in improved fuel efficiency and lower GHG emissions.
  • As part of our commitment to sustainability, Mosaic uses RightShip, a vetting service that allows the supply chain team to select vessels that meet certain safety and environmental criteria, including energy efficiency and GHG emissions performance.
  • Mosaic, along with our trucking partners, has implemented a number of fuel-saving initiatives, such as automatic engine shutoffs and reduced intra-company truck scaling. We have also invested in faster loading processes to both reduce fuel consumption and total trucks deployed.
  • Mosaic uses specialized Saddleback trailers to increase backhaul usage to reduce “dead head,” or empty loads. These unique trailers can transport molten sulfur from the Port of Tampa to our production facilities and return to the port with a load of our finished product for shipment to customers.

Mosaic uses CNG trucks to transport raw materials and finished products in our Central Florida operations

  • An N-ViroMotive locomotive, used at our South Fort Meade mine, uses approximately 57% less fuel and emits approximately 80% fewer GHGs than single-engine diesel locomotives.
  • Mosaic contracts a fleet of 50 clean-burning natural gas-powered trucks to transport raw materials and finished products in our Central Florida operations. Benefits include significantly lower emissions of particulates and nitrogen oxides (up to 50% lower) and GHGs (potentially up to 25% lower). We continue to explore opportunities to convert additional shipping volumes to compressed natural gas (CNG).

Waste Associated with Transportation

Mosaic has funded and promoted The Fertilizer Institute (TFI) Bulk Blend Workshops and Manual. Transporting and distributing our crop nutrient products in bulk greatly reduces the amount of packaging required to deliver our products to consumers. Most of our crop nutrient products are transported from production facilities to consumers in bulk quantities. Therefore, environmental impacts associated with packaging are eliminated. In some areas where small-scale farmers purchase our products, bulk distribution is not possible.

Land &

In our Florida phosphates operations, we conduct effective acre-for-acre reclamation and return mined lands to productive uses for both wildlife and people. We are a leader in using advanced science and technology to do this important work.

How & Where We Mine

(G4-EN11) As of Dec. 31, 2014, Mosaic owned or controlled about 355,815 acres of land in Florida related to our Phosphates mining operations. Approximately 109,460 acres of Mosaic’s land holdings in Florida are either in the mine permitting process or have not yet entered the permitting process. For each permit, Mosaic works with a team of professional biologists, hydrologists and other specialists, and in conjunction with as many as 12 local, regional, state and federal regulatory agencies to ensure that all mined areas can be successfully reclaimed and to identify areas of high environmental sensitivity that should be preserved and protected.

As of Dec. 31, 2014, Mosaic owns or controls more than 21,000 acres in Florida that are designated as non-impacted floodplain, preservation and granted conservation easements in order to ensure long-term protection of lands or waters of particular sensitivity.

We operate three Canadian Potash facilities, all located in the southern half of the province of Saskatchewan, including our solution mine at Belle Plaine, two interconnected mine shafts at our Esterhazy shaft mine and our shaft mine at Colonsay. Mosaic has mineral rights to approximately 575,000 acres in Saskatchewan for potash mining and surface rights to approximately 27,850 acres. Our U.S. Potash operations include a shaft mine in Carlsbad, N.M. We have mineral rights to approximately 77,000 acres in Carlsbad for potash mining and surface rights to approximately 7,186 acres. Since shaft mining in Saskatchewan occurs at over 3,000 feet below surface, and solution mining requires limited acreage for pipeline and cluster infrastructure, the only surface areas that are disturbed are the actual footprint of the mine shaft and the adjacent above- ground processing facilities and tailings management areas.

We mine phosphate ore in Florida through surface mining techniques with large earthmoving equipment such as draglines

ship in water

(G4-EN12) Mining for phosphate ore in Florida is primarily undertaken using surface mining techniques with large earthmoving equipment such as draglines. This is primarily because the ore body is overlaid by sandy soils with a high water table that is not conducive to underground mining. Due to its unique geology, a dredging technique is used at our Wingate mine.

During the mine permitting process, discussions regarding ecological resource preservation are held between Mosaic and the regulatory agencies. Preservation areas can include floodplains, as well as high-quality wetland or upland habitats and buffers. Such evaluations take into consideration the type and quality of the habitat. Balancing the supply of phosphate, an important natural resource, against what is generally a temporary disturbance of ecological resources, is an essential consideration in this process. To reduce the impact associated with lag time (the time period between initial land disturbance for mining and reclamation), Mosaic’s current pending permit applications include a “Regionally Ecologically Significant” (RES) project. An RES project involves one or more parcels of property located within the same watershed as the pending permit application that would not be mined, but rather would be restored to an improved ecological condition and then preserved through use of a conservation easement. Some areas of the RES project may include high-quality wetlands or other resources that are preserved in perpetuity through use of recorded conservation easements. The RES projects are permitted at the same time and linked to a proposed mining project, with restoration to be initiated upon receipt of all permits. This allows the restoration work to be completed well before—generally measured in terms of years—all the impacts for mining are made.

Once all permits are received, a wildlife survey is conducted prior to land clearing in preparation for mining to determine whether protected species are present and if so, whether they need to be physically relocated. Mosaic obtains government approvals and permits to physically relocate specific species, such as the gopher tortoise, in compliance with federal and state laws. After that process is complete, parcels are directionally cleared for mining to allow highly mobile animals to move to adjacent undisturbed or preservation areas. State law requires mining parcels to be recontoured and planted with vegetation within two years of the completion of mining activities; all wetlands are replaced at a minimum of acre for acre and type for type as needed to meet mitigation requirements. Once a particular parcel is mined and reclaimed, many vertebrates and invertebrates will repopulate the site through migration from wildlife corridors and protected riverine systems. Such habitat corridors generally receive permanent protection after mining, with perpetual conservation easements. To ensure biodiversity, Mosaic may introduce certain species into reclaimed lands, such as the gopher tortoise, that may have previously resided on the parcel but had been moved from the site prior to mining.

We mine potash in Saskatchewan and New Mexico using shaft and solution mining techniques

Phosphate mining in Florida, representing our largest phosphate reserve holdings, is heavily regulated by as many as 12 local, regional, state and federal permitting authorities. This robust regulatory oversight ensures the impacts of our mining operations are avoided and minimized in accordance with all legal and regulatory requirements. The benefit of that stringent regulatory oversight is supplemented with (a) areas that are set aside from mining, (b) reclamation practices that are best in class and (c) monitoring activities such as the Horse Creek Stewardship Program and Peace River Monitoring Programs, which are designed to monitor for and protect against significant impact to water quality, water quantity and biodiversity on these riverine systems both within or outside of our property boundaries.

Potash mining operations in Canada and the United States use shaft and solution mining techniques. Because of the limited footprint on surface features, impacts are highly localized to surface infrastructure and tailings management areas. Therefore, the impacts to wildlife and habitats are similarly highly localized.

Land Mined and Reclaimed

(G4-MM1) Mosaic reports our Florida mining and reclamation activities to the Florida Department of Environmental Protection (FDEP) Mining and Mitigation Program. As of the date of this publication’s release, 2013 and 2014 figures have not been deemed complete by the agency. We provide estimates of mined and reclaimed acres for those years in the table below. Once we have satisfied all reclamation obligations with respect to mined and disturbed lands, and the regulatory agencies “release” those reclaimed lands, they are considered “released acres.” Accordingly, a drop in annual reclaimed acreage may be the result of our satisfaction of reclamation obligations and agency release with respect to reclaimed acres and a resulting recategorization of the land as “released” acres.

Land Mined and Reclaimed

Total Acres Disturbed,
Not Reclaimed
Total Reclaimed Total Released

2014*, ** 12,320 5,320 3,776 2,214 2,994 2,740

*As of the date of this publication's release, this year's data has not been validated by FDEP. Accordingly, these figures are estimates only and may be revised in future reports.
**The increase in mined acres in 2014 is largely due to the inclusion of 7,761 acres from South Pasture mine as a result of the CF acquisition. This figure represents all mined acres for that location since its opening in 1995.

(G4-MM2) All active sites within the United States and Canada operate in compliance with federal, state/provincial and local regulations related to management of habitat and wildlife. Phosphate mining operations within the United States require extensive assessment of the proposed area of operation. Mosaic performs environmental site assessments, impact studies, hydrologic modeling and prepares conceptual reclamation plans prior to receiving a permit to operate on a parcel of land.

Biodiversity in flora and fauna is an important part of reclamation. Most mitigation plans have biodiversity requirements that must be monitored by qualified ecologists and reported to appropriate regulatory agencies as part of permit conditions or regulations. In fact, compliance with these biodiversity standards is a requirement that must be met before regulatory agencies will deem a site successfully reclaimed.

Protecting Biodiversity & Restoring Habitats

We are committed to minimizing our impacts on the environment through responsible mine planning, permitting, operation and reclamation practices.

(G4-EN13) In our Phosphate mining operations, we restore or reclaim every acre of land we mine, with certain areas of high environmental sensitivity set aside for preservation and protected into perpetuity with recorded conservation easements. Mined lands are reclaimed to land uses such as wildlife habitat (both wetlands and upland) and agricultural lands. Much of this land is also suitable for future conventional development such as parks, housing and commercial use.

Mosaic planted 2,064,817 trees in 2014, reclaiming uplands, significant upland habitats and wetlands that require, at a minimum, acre for acre and type for type per permitting requirements.

Additionally, Mosaic works closely with one of our primary regulators, the FDEP Mining and Mitigation Program, to integrate habitat networks and wildlife corridors into our reclamation planning efforts. The FDEP created, implements and encourages permittees to participate in the development of an Integrated Habitat Network to benefit the water quality and quantity in the area, improve wildlife habitat, and serve as a connection between the mining region’s rivers and significant environmental features outside the mining region.

As part of our reclamation efforts in Florida, we planted more than 2 million trees in 2014

Mosaic has fostered partnerships with, and funding for, a variety of non-governmental organizations (NGOs) and academic institutions to advance our understanding of the habitats we manage through reclamation. Examples of these groups include the Tampa Bay Watch, The Nature Conservancy and Audubon of Florida.

Mosaic’s Potash Business Unit is similarly committed to habitat restoration. For example, Mosaic made a grant to Ducks Unlimited for $2 million that will restore a minimum of 500 acres of wetlands over a 10-year period in Saskatchewan. 2014 marked the third year of this agreement.

(G4-EN14) The FDEP’s Mining and Mitigation Program oversees mining operations in Florida. The mine permitting process includes performing extensive ecological, wildlife and hydrological surveys, leading to the establishment of boundaries for preservation of areas identified as having important ecological or hydrological value. In our Potash facilities located in Saskatchewan, Canada, our approach to evaluating potential impacts to biodiversity includes biological assessments for projects located in new footprint areas. These assessments include field surveys to identify rare species of plants, birds, mammals, reptiles and amphibians of special concern that may be impacted. Survey methods follow those recommended by the Saskatchewan Conservation Data Centre. Biological assessments for all expansion areas at the Potash facilities followed this approach.

Phosphates and Potash operations’ interaction with wildlife in the United States is regulated by state agencies such as the Florida Fish and Wildlife Conservation Commission and by the United States Fish and Wildlife Service (USFWS). These state and federal agencies maintain lists of species, and Mosaic develops species-specific habitat management plans to ensure species are properly protected.

We work closely with regulators to not only ensure compliance with management plans, but to fund and/or conduct research that promotes the goal of wildlife and habitat conservation. Mosaic does not specifically track wildlife species per the International Union for Conservation of Nature (IUCN) Red List designations, but instead tracks species as designated by regulatory agencies with authority in the regions in which we operate.

Avian species listed as affected or possibly affected by New Mexico and Saskatchewan operations are migratory species with potential migration patterns proximal to our operations on those geographies. The table includes species and designations of the IUCN and not species and designations of federal or state/provincial agencies in the United States and Canada, by which Mosaic monitors threatened species.


Our conservation measures include providing more than 1,000 acres of managed and maintained gopher tortoise habitat

Additional Biodiversity Highlights

The gopher tortoise, a state-listed threatened species and a species that the USFWS has determined warrants federal protection, is commonly encountered on Mosaic lands in Central Florida. In 2012, Mosaic and the Florida Fish and Wildlife Conservation Commission entered into a 30-year Memorandum of Agreement (MOA) providing a comprehensive approach to gopher tortoise management and conservation on Mosaic lands. Conservation measures provided as part of the MOA include providing over 1,000 acres of gopher tortoise habitat in conservation easement that will be managed and maintained in perpetuity, with up to an additional estimated 2,500 acres (much of it reclaimed land) of tortoise habitat placed under conservation easement and perpetually managed over the life of the MOA. In addition, Mosaic will provide $60,000 per year ($1.8 million dollars over the life of the MOA) to The Nature Conservancy or similar organization to carry out gopher tortoise habitat management on non-Mosaic lands.

Since 2013, Belle Plaine has partnered with Wild and Cared Free, a wildlife rehabilitation organization dedicated to rehabilitating all species of animals in southern Saskatchewan. Mosaic has volunteered time and financial assistance to support the organization, and Wild and Cared Free has provided Mosaic access to training opportunities and rehabilitation services for animals around its Saskatchewan Potash mines.

The potash mine in Carlsbad, N.M., has developed an Avian and Bat Protection Plan to minimize risks to migratory birds and bats that can be attracted to mining and milling areas. Mosaic has also partnered with the USFWS to study risks associated with migratory birds and bats in order to develop future strategies aimed at minimizing avian and bat mortality.

G4-DMA: We aim to efficiently use the mineral resources and materials needed to make our crop nutrition products.


(G4-EN1) Our business mined or consumed the following raw materials in 2014:

Materials Mined or Consumed
in Million Tonnes

Ammonia 1.51
Limestone 0.47
Micronutrients 0.01
Phosphate Rock 16.01
Potash Ore 28.80
Sulfur 4.11

Note: Ammonia purchases depicted in the table above are for production of crop nutrients in Phosphates.

Limestone is used to produce our animal feed products and for water treatment processing. Sulfur, a byproduct of crude oil and natural gas de-sulfurization, is used to produce steam, electricity and sulfuric acid, which is used to produce phosphoric acid. We use byproduct heat from sulfuric acid production to generate steam that we use in our operations and to generate electricity. Sulfur is also used in the production of our MicroEssentials® product line. Various micronutrients, including boron, zinc, sulfur and cupric oxide, are key ingredients in our MicroEssentials product line. Ammonia is used in our finished products, diammonium phosphate (DAP), monoammonium phosphate (MAP) and MicroEssentials, and to neutralize the pH of the stack gases at our Esterhazy potash mine.

We support & promote TFI’s Bulk Blend Workshops & Manual, eliminating the need to package major raw materials & products

Products and Materials Reclaimed or Recycled

(G4-EN2) Sulfur is the most significant recycled raw material in our manufacturing processes. The sulfur used is recovered from crude oil and natural gas processing and then recycled in our plant operations to produce sulfuric acid, which we use to make phosphoric acid, steam and electricity. Our use of this product prevents an excess of sulfur that otherwise could be disposed of in landfills. In 2014, sulfur made up approximately 8.1% by weight of our total raw materials. We recover the vanadium catalysts used in our sulfuric acid production for recycling. We also use recycled oil as a flotation aid in our phosphate beneficiation process.

(G4-EN28) Mosaic products, predominantly fertilizer and animal feed ingredients, are used in various stages of agricultural operations with multiple steps and biological processes. To the extent possible, bulk transport is used to minimize the need for extensive packaging throughout the supply chain. Mosaic supports and helps promote The Fertilizer Institutes’s (TFI) Bulk Blend Workshops and Manual, which eliminates the need for packaging of major raw materials or the final product. This process completely eliminates the need for bags as the product is transferred from dealer to farmer. Because of the sizing and blending capabilities of our bulk materials, we encourage the use of the bulk blending and delivery system in farming operations.

Agricultural operation processes are not within Mosaic’s purview to control; however, the nutrient elements of our products often are recycled into these or other agricultural systems. Examples of these systems include:

  • Fertilizer is applied to the soil and then taken up by plants; the plants can be used for human or animal food. This food is processed and excreted by humans and animals as manure or biosolids, which may be recycled and used as nutrients similar to mineral fertilizers, depending on infrastructure (e.g., publicly-owned treatment works reuse water distribution systems).
  • Animal feed materials are taken up by animals as food and excreted as manure. These materials may be recycled and used as nutrients similar to mineral fertilizers, depending on infrastructure (e.g., feed lot versus free-range grazing).

To further encourage stewardship of our products, Mosaic has formed a product stewardship team from various disciplines and is pursuing opportunities to cooperate with supply chain and logistical partners to identify and implement stewardship enhancements on a global basis.

Mining Wastes

We use industry best practices to manage overburden, tailings and byproducts associated with our mining and production. We comply with federal, state and local regulations related to these materials.

(G4-MM3) Mining and processing of potash and phosphate generate residual materials that must be managed both during the operation of a facility and upon a facility’s closure. Potash tailings, consisting primarily of salt and clay, are stored in tailings management areas. A portion of the excess salt generated from potash mining is processed and then used for commercial purposes, including road salt, water softener salt, and use in food grade products and industrial uses. Phosphate clay residuals from mining are deposited in clay settling ponds. These ponds are eventually dewatered and reclaimed. Certain solid wastes generated by our phosphate operations may be subject to regulation under the Resource Conservation and Recovery Act (RCRA) and related state laws. The Environmental Protection Agency (EPA) rules exempt “extraction” and “beneficiation” wastes, as well as 20 specified “mineral processing” wastes, from the hazardous waste management requirements of the RCRA. Accordingly, certain residual materials which our phosphate operations generate, like phosphogypsum, as well as process wastewater from phosphoric acid production, are exempt from RCRA regulation. These materials (phosphogypsum and process wastewater) are subject to detailed state rules governing construction, operation, maintenance and closure.

Other Wastes

(G4-EN23) Mosaic’s operations generate a variety of non-hazardous solid wastes, including domestic refuse, construction and demolition debris, and waste lubricants. Mosaic has placed an emphasis on reducing and/or eliminating waste and our recycling program seeks to identify materials that can be diverted from landfills and recycled or reused. The following table summarizes materials recycled or reused in 2014.

We continue to improve our comprehensive waste management strategy, which complies with federal, state and local requirements and aligns to the Mosaic environmental health and safety management system. Below are examples of hazardous and non-hazardous wastes generated by disposal methods at Phosphates, Potash and international facilities. As our tracking of waste continues to improve, we anticipate further expanding the scope of our sustainability reporting for this indicator to include data for all facilities in the near future.

Each facility has an appropriate hazardous waste management system to ensure that waste is properly and safely disposed

(G4-EN25) We endeavor to choose on-site process chemicals that are the least hazardous, thereby ensuring lowest risk to occupational health and safety and minimizing waste management implications. Mosaic facilities generate hazardous waste during production and maintenance operations. In the United States, Mosaic’s Phosphate mines and Potash facilities are typically either categorized as Small Quantity or Conditionally Exempt Small Quantity Generators (which generate less than 2,200 pounds of hazardous waste per month). The five concentrate facilities in the Phosphates Business Unit are designated as Large Quantity Generators due to episodic generation of more than 2,200 pounds of hazardous waste in a month. Canadian facilities comply with all national regulations regarding these materials.

The types of hazardous waste generated at Mosaic’s U.S. facilities typically include spent cleaning solvents, paint-related wastes and some spent laboratory chemicals. At concentrate facilities, wastes generated during production and maintenance operations include waste that is characteristically hazardous for corrosivity and/or toxicity (e.g., low pH and/or metals content).
