Our mission is to provide clean energy to feed and fuel the world sustainably. With our employees focused on safe and reliable operations, environmental stewardship, and disciplined capital and corporate management, we are on a path to decarbonize our ammonia production network – the world’s largest – to enable green and blue hydrogen and nitrogen products for energy, fertilizer, emissions abatement and other industrial activities. Our nine manufacturing complexes in the United States, Canada and the United Kingdom, an extensive storage, transportation and distribution network in North America, and logistics capabilities enabling a global reach underpin our strategy to leverage our unique capabilities to accelerate the world’s transition to clean energy. Our principal customers are cooperatives, independent fertilizer distributors, traders, wholesalers and industrial users. Our core product is anhydrous ammonia (ammonia), which contains 82% nitrogen and 18% hydrogen. Our nitrogen products that are upgraded from ammonia are granular urea, urea ammonium nitrate solution (UAN) and ammonium nitrate (AN). Our other nitrogen products include diesel exhaust fluid (DEF), urea liquor, nitric acid and aqua ammonia, which are sold primarily to our industrial customers, and compound fertilizer products (NPKs), which are solid granular fertilizer products for which the nutrient content is a combination of nitrogen, phosphorus and potassium.

Our principal assets as of December 31, 2021 include:

• five U.S. nitrogen manufacturing facilities, located in Donaldsonville, Louisiana (the largest nitrogen complex in the world); Port Neal, Iowa; Yazoo City, Mississippi; Verdigris, Oklahoma; and Woodward, Oklahoma. These facilities are wholly owned directly or indirectly by CF Industries Nitrogen, LLC (CFN), of which we own approximately 89% and CHS Inc. (CHS) owns the remainder;

• two Canadian nitrogen manufacturing facilities, located in Medicine Hat, Alberta (the largest nitrogen complex in Canada) and Courtright, Ontario;

• two United Kingdom nitrogen manufacturing facilities, located in Billingham and Ince;

• an extensive system of terminals and associated transportation equipment located primarily in the Midwestern United States; and

• a 50% interest in Point Lisas Nitrogen Limited (PLNL), an ammonia production joint venture located in the Republic of Trinidad and Tobago that we account for under the equity method.

We have a strategic venture with CHS under which CHS owns an equity interest in CFN, a subsidiary of CF Holdings, which represents approximately 11% of the membership interests of CFN. We own the remaining membership interests. CHS also receives deliveries pursuant to a supply agreement under which CHS has the right to purchase annually from CFN up to approximately 1.1 million tons of granular urea and 580,000 tons of UAN at market prices. As a result of its minority equity interest in CFN, CHS is entitled to semi-annual cash distributions from CFN. We are also entitled to semi-annual cash distributions from CFN. See Note 18—Noncontrolling Interest for additional information on our strategic venture with CHS.

For the years ended December 31, 2021, 2020 and 2019, we sold 18.5 million, 20.3 million and 19.5 million product tons generating net sales of $6.54 billion, $4.12 billion and $4.59 billion, respectively.

Our Commitment to a Clean Energy Economy

We are taking significant steps to support a global hydrogen and clean fuel economy, through the production of green and blue ammonia. Since ammonia is one of the most efficient ways to transport and store hydrogen and is also a fuel in its own right, we believe that the Company, as the world’s largest producer of ammonia, with an unparalleled manufacturing and distribution network and deep technical expertise, is uniquely positioned to fulfill anticipated demand for hydrogen and ammonia from green and blue sources. Our approach includes green ammonia production, which refers to ammonia produced through a carbon-free process, and blue ammonia production, which relates to ammonia produced by conventional processes but with CO2 removed through carbon capture and sequestration (CCS) and other certified carbon abatement projects.

In October 2020, we announced an initial green ammonia project at our Donaldsonville complex. In April 2021, we signed an engineering and procurement contract with thyssenkrupp to supply a 20 MW alkaline water electrolysis plant to produce green hydrogen at our Donaldsonville complex. Construction and installation, which is being managed by us, began in the fourth quarter of 2021 and is expected to finish in 2023, with an estimated total cost of approximately $100 million. The cost of the project is expected to fit within our annual capital expenditure budgets. We will integrate the green hydrogen generated by the electrolysis plant into existing ammonia synthesis loops to enable the production of approximately 20,000 tons per year of green ammonia. We believe that, when completed in 2023, the Donaldsonville green ammonia project will be the largest of its kind in North America.

In the third quarter of 2021, we signed a memorandum of understanding with Mitsui & Co., Inc. (Mitsui) that will guide us in a joint exploration of the development of blue ammonia projects in the United States. The preliminary studies we are conducting with Mitsui cover areas such as blue ammonia supply and supply chain infrastructure, CO2 transportation and storage, expected environmental impacts, and blue ammonia economics and marketing opportunities in Japan and in other countries.

We have also announced steps to produce blue ammonia from our ammonia production network. In the fourth quarter of 2021, our Board of Directors authorized projects that will enable the annual production of up to 1.25 million tons of blue ammonia from our existing network starting in 2024. The projects will involve constructing units at our Donaldsonville and Yazoo City complexes that dehydrate and compress CO2, a process essential for CO2 transport via pipeline to sequestration sites. Management expects that, once the units are in service and sequestration is initiated, we could sequester up to 2.5 million tons of CO2 per year (2 million tons at Donaldsonville and 500,000 tons at Yazoo City). Under current regulations, the projects would be expected to qualify for tax credits under Section 45Q of the Internal Revenue Code, which provides a credit per tonne of CO2 sequestered.

Construction of the units at the Donaldsonville complex is expected to begin in 2022 and to be completed in 2024, with an estimated total cost of $200 million. The Yazoo City project will be timed to coincide with CO2 transport pipeline construction. Once started, the project is expected to be completed in three years with an estimated total cost of $85 million. In addition, we are currently in advanced discussions with several parties regarding transportation and sequestration of CO2 from Donaldsonville.

Company History

We were founded in 1946 as Central Farmers Fertilizer Company, and were owned by a group of regional agriculture cooperatives for the first 59 years of our existence. Central Farmers became CF Industries in 1970.

Originally established as a fertilizer brokerage company, we expanded owning and operating fertilizer manufacturing and distribution facilities in the early 1950s with a principal objective of assured supply for our owners. At various times in our history, we manufactured and/or distributed nitrogen, phosphate and potash fertilizers.

We operated as a traditional manufacturing and supply cooperative until 2002, when we adopted a new business model that established financial performance as our principal objective, rather than assured supply for our owners. A critical aspect of the new business model was to establish a more economically driven approach to the marketplace.

In August 2005, we completed our initial public offering (IPO) of common stock, which is listed on the New York Stock Exchange. In connection with the IPO, we consummated a reorganization transaction whereby we ceased to be a cooperative and our pre-IPO owners’ equity interests in CF Industries were canceled in exchange for all of the proceeds of the offering and shares of our common stock. At the time of the IPO, our assets consisted of one wholly owned nitrogen manufacturing facility

CF INDUSTRIES HOLDINGS, INC.

in Louisiana, United States; a joint venture nitrogen manufacturing facility in Alberta, Canada, of which we owned 66 percent; a phosphate mining and manufacturing operation in Florida, United States; and distribution facilities throughout North America.

In April 2010, we acquired Terra Industries Inc. (Terra), a leading North American producer and marketer of nitrogen fertilizer products for a purchase price of $4.6 billion, which was paid in cash and shares of our common stock. As a result of the Terra acquisition, we acquired five nitrogen fertilizer manufacturing facilities, an approximately 75.3% interest in Terra Nitrogen Company, L.P. (TNCLP) and certain joint venture interests.

In March 2014, we exited our phosphate mining and manufacturing business, which was located in Florida, through a sale to The Mosaic Company for approximately $1.4 billion in cash. As a result, our company became focused solely on nitrogen manufacturing and distribution.

In July 2015, we acquired the remaining 50% equity interest in CF Fertilisers UK Group Limited (formerly known as GrowHow UK Group Limited) (CF Fertilisers UK) not previously owned by us for total consideration of $570 million, and CF Fertilisers UK became wholly owned by us. This transaction added CF Fertilisers UK’s nitrogen manufacturing complexes in Ince, United Kingdom and Billingham, United Kingdom to our consolidated manufacturing capacity.

In February 2016, our strategic venture with CHS commenced, at which time CHS made a capital contribution of $2.8 billion to CFN in exchange for membership interests in CFN, which represented approximately 11% of the total membership interests of CFN.

In late 2015 and 2016, we completed certain capacity expansion projects at Donaldsonville, Louisiana and Port Neal, Iowa. These projects, originally announced in 2012, included the construction of new ammonia, urea, and UAN plants at our Donaldsonville, Louisiana complex and new ammonia and urea plants at our Port Neal, Iowa complex. These plants increased our overall production capacity by approximately 25%, improved our product mix flexibility at Donaldsonville, and improved our ability to serve upper-Midwest urea customers from our Port Neal location. The total capital cost of the capacity expansion projects was $5.2 billion.

Prior to April 2, 2018, Terra Nitrogen, Limited Partnership, which owns and operates our nitrogen manufacturing facility in Verdigris, Oklahoma, was a subsidiary of TNCLP. TNCLP was a publicly traded limited partnership of which we were the sole general partner and the majority limited partner, and in which we owned an approximate 75.3% interest.

In 2018, we announced that, in accordance with the terms of TNCLP’s First Amended and Restated Agreement of Limited Partnership (as amended by Amendment No. 1 to the First Amended and Restated Agreement of Limited Partnership, the TNCLP Agreement of Limited Partnership), Terra Nitrogen GP Inc. (TNGP), the sole general partner of TNCLP and an indirect wholly owned subsidiary of CF Holdings, elected to exercise its right to purchase all of the 4,612,562 publicly traded common units of TNCLP (the TNCLP Public Units). On April, 2, 2018, TNGP completed its purchase of the TNCLP Public Units (the Purchase) for an aggregate cash purchase price of $388 million. We funded the Purchase with cash on hand. Upon completion of the Purchase, CF Holdings owned, through its subsidiaries, 100 percent of the general and limited partnership interests of TNCLP.

Product Tons and Nutrient Tons

Unless otherwise stated, we measure our production and sales volume in this Annual Report on Form 10-K in product tons, which represents the weight of the product measured in short tons (one short ton is equal to 2,000 pounds). References to UAN product tons assume a 32% nitrogen content basis for production volume.

We also provide certain supplementary volume information measured in nutrient tons. Nutrient tons represent the weight of the product’s nitrogen content, which varies by product. Ammonia represents 82% nitrogen content, granular urea represents 46% nitrogen content, UAN represents between 28% and 32% nitrogen content and AN represents between 29% and 35% nitrogen content.

Reportable Segments

Our reportable segments consist of the following segments: ammonia, granular urea, UAN, AN and Other. These segments are differentiated by products. We use gross margin to evaluate segment performance and allocate resources. Total other operating costs and expenses (consisting primarily of selling, general and administrative expenses and other operating—net) and non-operating expenses (consisting primarily of interest and income taxes), are centrally managed and are not included in the measurement of segment profitability reviewed by management. See Note 22—Segment Disclosures for additional information.

Point Lisas, Trinidad

The Point Lisas Nitrogen facility in the Republic of Trinidad and Tobago is owned jointly through a 50/50 venture with Koch Fertilizer LLC. This facility has the capacity to produce 720,000 tons of ammonia annually from natural gas supplied under a contract with The National Gas Company of Trinidad and Tobago Limited (NGC).

Nitrogen Product Raw Materials

Natural gas is the principal raw material and primary fuel source used in the ammonia production process at our nitrogen manufacturing facilities. In 2021, natural gas accounted for approximately 40% of our total production costs for nitrogen products. Our nitrogen manufacturing facilities have access to abundant, competitively-priced natural gas through a reliable network of pipelines that are connected to major natural gas trading hubs. Our facilities utilize the following natural gas hubs: Henry Hub in Louisiana; SONAT and TETCO ELA in Louisiana; ONEOK in Oklahoma; AECO in Alberta; Ventura in Iowa; Demarcation in Kansas; Welcome in Minnesota; Dawn and Parkway in Ontario; and the National Balancing Point (NBP) in the United Kingdom.

In 2021, our nitrogen manufacturing facilities consumed, in the aggregate, approximately 335 million MMBtus of natural gas. We employ a combination of daily spot and term purchases from a variety of quality suppliers to maintain a reliable, competitively-priced supply of natural gas. We also use certain financial instruments to hedge natural gas prices. See Note 16—Derivative Financial Instruments for additional information about our natural gas hedging activities.

Nitrogen Product Distribution

The safe, efficient and economical distribution of nitrogen products is critical for successful operations. Our nitrogen production facilities have access to multiple transportation modes by which we ship products to terminals, warehouses and customers. Each of our production facilities has a unique distribution pattern based on its production capacity and location.

CF INDUSTRIES HOLDINGS, INC.

Our North American nitrogen production facilities can ship products via truck and rail to customers and to our storage facilities in the U.S. and Canada, with access to our leased railcar fleet of approximately 5,000 tank and hopper cars, as well as railcars provided by rail carriers. Our United Kingdom nitrogen production facilities mainly ship products via truck.

The North American waterway system is also used extensively to ship products from our Donaldsonville, Verdigris and Yazoo City facilities. To ship ammonia and UAN, we employ a fleet of ten tow boats and twenty-eight river barges, which are primarily leased. We also utilize contract marine services to move granular urea. We can also export nitrogen products via seagoing vessels from our Donaldsonville, Yazoo City, Billingham and Ince manufacturing facilities.

The Donaldsonville facility is connected to the 2,000-mile long Nustar pipeline through which we have the ability to transport ammonia to ten terminals and shipping points in the Midwestern U.S. corn belt.

Storage Facilities and Other Properties

As of December 31, 2021, we owned or leased space at 51 in-market storage terminals and warehouses located in a 21-state region of the United States, Canada and the United Kingdom. Including storage at our production facilities, we have an aggregate storage capacity for approximately 3.0 million tons of product. Our storage capabilities are summarized in the following table:

			Ammonia												Granular Urea												UAN**(1)**												AN
			Number of Facilities						Capacity (000 Tons)						Number of Facilities						Capacity (000 Tons)						Number of Facilities						Capacity (000 Tons)						Number of Facilities						Capacity (000 Tons)

(1)Capacity is expressed as the equivalent volume of UAN measured on a 32% nitrogen content basis.

(2)The owned facilities that store UAN also can store ammonia.

(3)Our lease agreements are typically for periods of one to five years.

Customers

The principal customers for our nitrogen products are cooperatives, independent fertilizer distributors, traders, wholesalers and industrial users. Sales are generated by our internal marketing and sales force. CHS was our largest customer in 2021 and accounted for approximately 14% of our consolidated net sales. We have a strategic venture with CHS under which CHS has a minority equity interest in CFN. See Note 18—Noncontrolling Interest for additional information on our strategic venture with CHS.

Competition

Our markets are global and intensely competitive, based primarily on delivered price and, to a lesser extent, on customer service and product quality. During the peak demand periods, product availability and delivery time also play a role in the buying decisions of customers.

Our primary North American-based competitors include Nutrien Ltd., Koch Fertilizer LLC and Iowa Fertilizer Company. There is also significant competition from products sourced from other regions of the world, including some with lower natural gas or other feedstock costs, which may include the benefit of government subsidies. Because ammonia, urea and UAN are widely-traded fertilizer products and there are limited barriers to entry, we experience competition from foreign-sourced products continuously. Producers of nitrogen-based fertilizers located in the Middle East, the Republic of Trinidad and Tobago, North Africa and Russia have been major exporters to North America in recent years.

Our primary United Kingdom competition comes from imported products supplied by companies including Yara International, Origin Fertilisers, Ameropa, CHS and Helm. Urea and UAN are not produced in the United Kingdom, but along with AN are widely-traded fertilizer products with limited barriers to entry.

CF INDUSTRIES HOLDINGS, INC.

Seasonality

The fertilizer business is seasonal. The degree of seasonality of our business can change significantly from year to year due to weather conditions in the agricultural industry and other factors. The strongest demand for our products in North America occurs during the spring planting season, with a second period of strong demand following the fall harvest. In contrast, we and other fertilizer producers generally manufacture and distribute products throughout the year. As a result, we and/or our customers generally build inventories during the low demand periods of the year to ensure timely product availability during the peak sales seasons. Seasonality is greatest for ammonia due to the short application season and the limited ability of our customers and their customers to store significant quantities of this product. The seasonality of fertilizer demand generally results in our sales volumes and net sales being the highest during the spring and our working capital requirements being the highest just prior to the start of the spring planting season. Our quarterly financial results can vary significantly from one year to the next due to weather-related shifts in planting schedules and purchasing patterns.

Environmental, Health and Safety

We are subject to numerous environmental, health and safety laws and regulations in the United States, Canada, the United Kingdom, the European Union and the Republic of Trinidad and Tobago, including laws and regulations relating to the generation and handling of hazardous substances and wastes; the introduction of new chemicals or substances into a market; the cleanup of hazardous substance releases; the discharge of regulated substances to air or water; and the demolition of existing plant sites upon permanent closure. In the United States, these laws include the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act (RCRA), the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the Toxic Substances Control Act (TSCA), the Occupational Safety and Health Act (OSHA) and various other federal, state and local statutes. Violations of environmental, health and safety laws can result in substantial penalties, court orders to install pollution-control equipment, civil and criminal sanctions, permit revocations and facility shutdowns. In addition, environmental, health and safety laws and regulations may impose joint and several liability, without regard to fault, for cleanup costs on potentially responsible parties who have released or disposed of hazardous substances into the environment. We may be subject to more stringent enforcement of existing or new environmental, health and safety laws in the future.

Environmental, Health and Safety Expenditures

Our environmental, health and safety capital expenditures in 2021 totaled approximately $31 million. We estimate that we will have approximately $63 million of capital expenditures for environmental, health and safety in 2022. In addition, to support safe and reliable operations at our continuous process manufacturing facilities, we conduct scheduled inspections, replacements and overhauls of our plant machinery and equipment, which are referred to as turnarounds. A further description of turnaround activities is included in Note 7—Property, Plant and Equipment—Net to our consolidated financial statements included in Item 8 of this report. Environmental, health and safety laws and regulations are complex, change frequently and have tended to become more stringent over time. We expect that continued government and public emphasis on environmental issues will result in increased future expenditures for environmental controls at our manufacturing and distribution facilities. Such expenditures could have a material adverse effect on our business, financial condition, results of operations and cash flows. Additionally, future environmental, health and safety laws and regulations or reinterpretation of current laws and regulations may require us to make substantial expenditures. Our costs to comply with, or any liabilities under, these laws and regulations could have a material adverse effect on our business, financial condition, results of operations and cash flows.

CERCLA/Remediation Matters

From time to time, we receive notices from governmental agencies or third parties alleging that we are a potentially responsible party at certain cleanup sites under CERCLA or other environmental cleanup laws. In 2011, we received a notice from the Idaho Department of Environmental Quality (IDEQ) that alleged that we were a potentially responsible party for the cleanup of a former phosphate mine site we owned in the late 1950s and early 1960s located in Georgetown Canyon, Idaho. The current owner of the property and a former mining contractor received similar notices for the site. Based on a Consent Order entered into with IDEQ and the U.S. Forest Service in 2014, we and the current property owner are currently conducting a remedial investigation and feasibility study of the site. In 2015, we and several other parties received a notice that the U.S. Department of the Interior and other trustees intend to undertake a natural resource damage assessment for 18 former phosphate mines and three former processing facilities in southeast Idaho, which includes the Georgetown Canyon former mine and processing facility. See Note 21—Contingencies for additional information.

Regulation of Greenhouse Gases

Our production facilities emit greenhouse gases (GHGs), such as carbon dioxide and nitrous oxide. Natural gas, a fossil fuel, is a primary raw material used in our nitrogen production process. We are subject to GHG regulations in the United Kingdom, Canada and the United States.

Our U.K. manufacturing plants are required to report GHG emissions annually to the United Kingdom Environment Agency pursuant to their site Environmental Permits and Climate Change Agreement, which specify energy efficiency targets. Failure to meet efficiency targets may require these plants to purchase CO2 emissions allowances. Our facilities were previously subject to the European Union Greenhouse Gas Emission Trading System (EU ETS), which generally required us to hold or obtain emission allowances to offset GHG emissions from those aspects of our operations that were subject to regulation under this program. Beginning on January 1, 2021, our U.K. manufacturing plants became subject to the UK Emissions Trading Scheme (UK ETS). The UK ETS is similar to the EU ETS, although the U.K. ETS regulations established a lower emission cap than was established under the EU ETS. No agreement has been reached as to whether the UK ETS will establish a linkage with the EU ETS or other national emission trading systems.

In Canada, we are required to conduct an annual review of our operations with respect to compliance with Environment Canada’s National Pollutant Release Inventory and Ontario’s Mandatory Monitoring and Reporting Regulation and the GHG Reporting Regulation. In 2018, the federal Greenhouse Gas Pollution Pricing Act came into effect, pursuant to which Environment and Climate Change Canada (ECCC) implemented the Output-Based Performance Standard (OBPS), which was intended to function as a backstop to provincial greenhouse gas emissions regulations. In June 2019, the ECCC finalized the emission limits for carbon dioxide equivalent (CO2e) emissions from nitrogen fertilizer products. These emission limits are based on 95% of the average emissions intensity for the production of such products from all Canadian nitrogen fertilizer plants, reflecting that such products are deemed to be energy-intensive and trade-exposed and thus subject to a less stringent emissions reduction requirement. In the provinces and territories where the OBPS applies, a facility whose carbon emissions exceed the applicable limits is required to offset emissions by obtaining and retiring surplus emission credits, obtaining qualifying emissions offsets, or paying a fee. The fee under the OBPS for calendar year 2021 was CAD $40 per tonne of excess carbon dioxide equivalent emissions, and will be CAD $50 per tonne in 2022. Under the current program, the excess emission fee will increase by CAD $15 per year after 2022, reaching CAD $170 per tonne by 2030. Ontario, Saskatchewan and Alberta filed suit challenging whether the federal government had jurisdiction to impose a federal carbon price on the provinces and territories, but in March 2021, the Supreme Court of Canada upheld the constitutionality of the Greenhouse Gas Pollution Pricing Act.

In July 2019, the Ontario government enacted a new GHG regulation, called the Emissions-Performance Standards program (EPS), that sets CO2e emissions limits for nitrogen products based on a production weighted sectoral average. For facilities whose carbon emissions exceed the applicable limit, compliance options include the purchase of excess emission units, for a fee of CAD $40 per unit purchased in 2022 (which can be used to offset excess emissions in the 2021 calendar period) and CAD $50 per unit purchased in 2023 (to offset excess emissions in calendar year 2022). In September 2020, ECCC announced that the Ontario EPS met the federal government’s minimum stringency benchmark requirements, and in September 2021, the ECCC announced that the federal OBPS would no longer apply in Ontario beginning in January 2022. Accordingly, the Ontario EPS became applicable on January 1, 2022.

In 2019, the Alberta government passed the Technology Innovation and Emission Reduction Implementation Act (TIER), which went into effect on January 1, 2020. The TIER requires large emitting facilities (other than electricity producers, which are subject to a different standard) to comply with the least stringent of a “facility-specific” benchmark of 90% of historical GHG emissions intensity from a three-year baseline, which intensity limit will be reduced by 1% a year beginning in 2021, or a benchmark reflecting the emissions intensity of the top 10% of facilities for a given sector. The compliance options under the TIER initially established the price for payments into its carbon fund at CAD $30 per excess tonne of emissions. In December 2019, the federal government determined that the TIER met the stringency requirements of the OBPS with respect to its regulation of large industrial emitters for 2020. The levy for excess emissions of CO2e in Alberta for 2021 was CAD $40 per tonne and it is anticipated that the Alberta government will increase the levy for excess emissions of CO2e for calendar year 2022 to CAD $50 per tonne, to match the price of carbon established in the OBPS.

In the United States, GHG regulation is evolving at state, regional and federal levels, although some of the more significant developments to date, including efforts of the United States Environmental Protection Agency (EPA) to regulate GHG emissions from fossil fuel-fired power plants, do not directly impose obligations on our facilities. The EPA issued a mandatory GHG reporting rule that required all of our U.S. manufacturing facilities, which are considered large emitters of GHGs, to commence monitoring GHG emissions beginning on January 1, 2010 and reporting the previous year’s emissions annually starting in 2011. In addition, if we seek to modify or expand any of our major facilities and as a result, are required to

CF INDUSTRIES HOLDINGS, INC.

obtain a Prevention of Significant Deterioration (PSD) construction permit applicable to such facilities, we could be subject to pollution control requirements applicable to GHGs in addition to requirements applicable to conventional air pollutants. Such requirements may result in increased costs or delays in completing such projects. Other than the states’ implementation of this permitting requirement, none of the states where our U.S. production facilities are located-Iowa, Louisiana, Mississippi and Oklahoma-has proposed control regulations limiting GHG emissions.

Increasing concern over the impacts of climate change is driving countries to establish ever more ambitious GHG reduction targets. Approximately 200 countries, including the United States, Canada, the United Kingdom and the European Union (EU) have joined the Paris Agreement, an international agreement intended to provide a framework pursuant to which the parties to the agreement will attempt to hold the increase in global average temperatures to below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels. Each signatory is required to develop its own national plan to attain this objective. In December 2020, the United Kingdom announced a target to reduce GHG emission 68% from 1990 levels by 2030. Canada has increased its emissions reduction target under the Paris Agreement to 40-45% below 2005 levels by 2030, up from 30%. In April 2021, the United States increased its goal to reduce GHG emissions to 50-52% below 2005 levels by 2030. Executive orders issued by the Biden administration, including in particular an executive order issued on January 27, 2021 focusing on climate change, evidence the administration’s intent to undertake numerous initiatives in an effort to reduce GHG emissions, including promoting renewable energy development, limiting or prohibiting new oil and gas leases on federal lands, and in general, making climate change considerations a critical component of federal policy.

Regulatory Permits and Approvals

We hold numerous environmental and other governmental permits and approvals authorizing operations at each of our facilities. A decision by a government agency to deny or delay issuing a new or renewed regulatory material permit or approval, or to revoke or substantially modify an existing material permit or approval, could have a material adverse effect on our ability to continue operations at the affected facility. Any future expansion of our existing operations is also predicated upon securing the necessary environmental or other permits or approvals. More stringent environmental standards may impact our ability to obtain such permits.

Human Capital Resources

Our long-term success depends on our people. We are dedicated to creating a workplace where employees are proud to work and grow and where everyone feels empowered to do their best work. We do this by investing in extensive recruitment, training and professional development opportunities for our employees and fostering diversity and inclusion in our culture.

Employee Population. We employed approximately 3,000 employees at December 31, 2021, of which 67% were located in the United States, 19% in the United Kingdom, and 14% in Canada. As of December 31, 2021, 14% of our employees have worked for the Company more than 20 years, 17% of our employees have worked for the Company between 11 and 20 years, 29% of our employees have worked for the Company between 6 and 10 years, and 40% of our employees have worked at the Company for less than 6 years. Full-time employees represented approximately 99% of our workforce as of December 31, 2021 and approximately 15% were covered by a collective bargaining agreement. We supplement our workforce with contractors with specialized skill sets during periods of peak activity, such as during turnarounds and maintenance events.

Culture, Inclusion and Diversity. Our core values and their underlying principles reflect our commitment to a diverse and inclusive culture, treating one another with respect. Across the Company, all employees completed training to learn to recognize and address the effects of unconscious bias by challenging assumptions; encouraging diversity of experience, opinion, and expression; and supporting a workplace culture that actively strives to be more inclusive. As of December 31, 2021, approximately 14% of our global workforce was female and 16% of the Company’s employees in frontline managerial roles were female. Minorities represented approximately 14% of the Company’s U.S. workforce and 13% of our U.S. employees in managerial roles. In order to continue to improve the inclusiveness and diversity of our company and culture, our comprehensive ESG goals announced in 2020 include goals to increase the representation of females and persons of color in senior leadership roles and to implement a program designed to increase the hiring and promotion of minority and female candidates. As of December 31, 2021, we had exceeded our representation goal with approximately 38% of senior leadership roles held by females and persons of color.

Workforce Health and Safety. Operating in a safe and responsible manner is a core value and an integral part of what sets the Company apart. We believe that focusing on leading indicators - such as the behavioral safety practices we have incorporated into our annual incentive plan - to drive and measure activities that prevent and control safety incidents, results in our industry-leading safety record. As of December 31, 2021, our employee 12-month rolling average recordable incident rate (RIR) was 0.32 incidents per 200,000 work hours, and our total recordable injury count was nine. For the year ended December

CF INDUSTRIES HOLDINGS, INC.

31, 2021, our days away, restricted or transferred (DART) incident rate was 0.21 injuries per 200,000 work hours, and our lost time incident rate was 0.11.

Response to COVID-19 Pandemic. During fiscal 2020 and 2021, in response to the COVID-19 pandemic, we instituted and have continued to enforce safety precautions to protect the health and well-being of all of our employees, including the manufacturing workforce who operate our nitrogen manufacturing complexes and distribution facilities. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview of CF Holdings—Market Conditions and Current Developments—COVID-19 Pandemic, for a further discussion of the pandemic.

Talent Development. A core aspect of our culture is our commitment to identifying and developing talent to help employees accelerate growth and achieve their career goals. We invest in extensive assessment, training and professional development opportunities for our employees through a robust set of formal and informal programs, including targeted job movements, key experiences, and training, with an emphasis on creating a culture of inclusion. Leadership is the quality that drives our values and sets us apart. To help foster leadership, we have developed a set of leadership competencies that provide a common language for how to demonstrate leadership at every level of the organization. We view training and development programs as being a key part of succession planning, allowing us to grow a stronger company today and in the future.
