Fossil fuels are used to produce fertilizers and pesticides, contributing to the climate crisis. The production of fertilizers and pesticides requires a significant amount of energy, which is often derived from burning fossil fuels. This process emits carbon dioxide (CO2) and other heat-trapping gases, such as nitrous oxide and methane, leading to an increase in greenhouse gas emissions. Additionally, the use of fertilizers and pesticides in agriculture has negative environmental impacts, including soil damage, water pollution, and biodiversity loss. The close connection between the agrochemical and fossil fuel industries further reinforces their role in driving climate change.

Fossil fuels are used to produce ammonia, a critical input in fertilizers
Fossil fuels are essential in the production of synthetic fertilizers and pesticides, and their use in agriculture has significantly increased food production and supported global population growth. However, this heavy reliance on fossil fuels has also led to adverse environmental and sustainability concerns, including increased greenhouse gas emissions, resource depletion, and harmful impacts on water sources and biodiversity.
Nitrogen, phosphorus, and potassium are the primary nutrients required by plants, and synthetic fertilizers are produced to provide these essential elements. The production of nitrogen-based fertilizers, the largest product group, involves combining nitrogen from the air with hydrogen derived from natural gas at high temperatures and under pressure to create ammonia. This ammonia is then used to make nitric acid, which is mixed to produce nitrate fertilizers. The Haber-Bosch process, used in nitrogen fertilizer production, is energy-intensive, requiring significant amounts of fossil fuels as an energy source.
Fossil gas-based ammonia, or "blue" ammonia, is a critical input in fertilizers. Oil, gas, and agrochemical companies are partnering on projects that aim to produce this "blue" ammonia using carbon capture and storage (CCS) technology. While these companies promote this approach as a solution to the climate crisis, it also serves their interests in securing additional revenue streams and improving their public image.
The production of ammonia for fertilizer using fossil fuels generates significant carbon dioxide (CO2) emissions, contributing more CO2 than any other industrial chemical reaction. Additionally, the release of other potent heat-trapping gases, such as nitrous oxide (N2O) and methane (CH4), further exacerbates the environmental impact of fertilizer production. The fertilizer industry is responsible for an estimated 5% of global heat-trapping emissions.
The close ties between the fossil fuel and agrochemical industries have resulted in a fossil-fueled system that has detrimental effects on the planet and human rights. The dependence of synthetic fertilizers on fossil fuels highlights the urgent need for alternative farming practices, regenerative models, and sustainable agricultural technologies.

Nitrogen fertilizers are made using fossil fuels
Nitrogen is one of the most important mineral nutrients that plants need. In natural ecosystems like forests and grasslands, plants get nitrogen from the excretion of nitrogen in the manure and urine of animals. This, along with the breakdown of dead and decomposing plants, incorporates nitrogen into the soil for the next growing season.
However, in modern agricultural practices, the vast majority of agricultural production in the United States is fuelled by synthetic fertilizers. Nitrogen fertilizers are manufactured using fossil fuels, specifically fossil gas, based on a century-old method that originally produced nitrogen for explosives. The production of nitrogen-based fertilizers involves the Haber-Bosch process, which combines nitrogen gas (N2) from the atmosphere with hydrogen gas (H2), usually obtained from fossil fuels. This process requires high temperatures and pressures, which necessitate the use of significant amounts of fossil fuels as an energy source.
The energy-intensive nature of nitrogen fertilizer production makes it heavily reliant on fossil fuels. It is estimated that about 1-2% of the world's energy supply is dedicated to the Haber-Bosch process, highlighting its significant environmental footprint. While this process has increased food production and supported global population growth, it has also led to increased emissions of carbon dioxide and other greenhouse gases, contributing to climate change.
The use of fossil fuels in nitrogen fertilizer production has raised several environmental and sustainability concerns. Firstly, it contributes to greenhouse gas emissions, which are a primary driver of climate change. Secondly, the reliance on non-renewable fossil fuels raises concerns about resource depletion and long-term sustainability. Lastly, the use of nitrogen fertilizers can lead to runoff and leaching of chemicals into water sources, causing eutrophication and other harmful environmental effects, such as soil degradation and loss of biodiversity.
The close ties between nitrogen fertilizers and fossil fuels also have economic implications. The industrial food production system is vulnerable to the volatility of oil and gas markets, as illustrated by the 2022 market shocks in food, fuel, and fertilizer prices. As the world moves away from oil and gas as fuels, the fossil fuel industry has been seeking new avenues for profit by partnering with the fertilizer industry to produce fossil gas-based products, such as "blue" ammonia, to be used as a critical fertilizer input.

Fossil fuel companies are partnering with agrochemical companies to produce fossil fuel-based fertilizers
The production of synthetic fertilizers and pesticides requires a significant amount of energy, which is mainly derived from fossil fuels such as coal, oil, and natural gas. This energy-intensive process, known as the Haber-Bosch process, combines nitrogen gas (N2) from the atmosphere with hydrogen gas (H2), typically sourced from natural gas. The high temperatures and pressures involved make fossil fuels an essential energy source. Consequently, the production of synthetic fertilizers and pesticides is heavily reliant on fossil fuels, giving rise to concerns about greenhouse gas emissions, resource depletion, and environmental degradation.
In light of these concerns, fossil fuel companies are joining forces with agrochemical companies to produce fossil fuel-based fertilizers. This alliance is driven by a mutual interest in sustaining their businesses in the face of a transitioning energy landscape. As the world moves away from oil and gas as primary fuels, fossil fuel companies are seeking new avenues for profit, such as petrochemicals and partnerships with the agrochemical industry. By collaborating with agrochemical companies, fossil fuel companies can maintain their relevance and tap into new markets.
Agrochemical companies, on the other hand, rely on fossil fuels as feedstock for their products, particularly nitrogen-based fertilizers. This interdependence between the industries has led to deep connections and shared interests, with some agrochemical companies even directly engaging in fossil fuel production. Together, they are pursuing initiatives that purportedly address climate challenges while also ensuring their continued profitability. One such initiative involves the use of carbon capture and storage (CCS) technology to produce fossil gas-based "blue" ammonia and its blue" hydrogen precursor.
By promoting "blue" ammonia as a clean energy source and critical fertilizer input, both industries stand to benefit from substantial government subsidies and access to new markets as "clean energy companies." However, critics argue that these initiatives are merely greenwashing, as they fail to address the underlying environmental and social impacts of their industries. The continued reliance on fossil fuels and industrial agriculture contributes to climate change, biodiversity loss, toxic pollution, and the violation of human rights.
To summarize, fossil fuel companies are partnering with agrochemical companies to produce fossil fuel-based fertilizers by leveraging shared interests and technologies. While they promote these collaborations as solutions to climate challenges, they simultaneously perpetuate a fossil fuel-dependent system that poses significant risks to the planet and its inhabitants.

Fossil fuel-based pesticides are linked to greenhouse gas emissions
Fossil fuels are used in the production and transportation of pesticides, contributing to greenhouse gas emissions. The production of pesticides requires a significant amount of energy, which often comes from fossil fuels such as coal, oil, and natural gas. The synthesis of the necessary chemicals and the extraction, transportation, and processing of raw materials like petroleum contribute to their carbon footprint.
The use of fossil fuels in the production of pesticides is linked to greenhouse gas emissions, which are a primary driver of climate change. Researchers have calculated the energy use associated with pesticide production, which can be used to estimate carbon dioxide emissions. For example, the manufacture of glyphosate, a widely used herbicide, produces 31.29 kilograms of carbon dioxide equivalent (CO2e) per kilogram of product. Several pesticides produce greater amounts, exceeding 40 kilograms of CO2e per kilogram.
Additionally, many pesticides are coated in microplastics, which are derived from fossil fuels and help control the release of the product. The active ingredients in pesticides, synthesized from hydrocarbons derived from petroleum, are combined with other elements to create chemical intermediates, and this process is responsible for greenhouse gas emissions. The energy-intensive nature of pesticide production relies on fossil fuels for both the hydrogen source and the heat and pressure needed for the reaction.
Furthermore, the use of fossil fuel-based pesticides supports unsustainable food and farming systems and affects the soil's ability to sequester carbon. Pesticides also contribute to emissions through their effects on soils, although these impacts are not yet fully understood. For instance, soil fumigants like chloropicrin can significantly increase soil N2O emissions, and their effects can outlast fertiliser-induced emissions.
The Intergovernmental Panel on Climate Change (IPCC) warns that without significant reductions in carbon dioxide and other greenhouse gas emissions, global warming will exceed 2°C, requiring a rapid transition. Fossil fuel-based pesticides contribute to climate change through direct emissions from their production and by enabling the damaging practices of industrial agriculture.

For nitrogen-based fertilizers, the most common type, the production process involves combining nitrogen from the air with hydrogen derived from natural gas at high temperatures and pressures to create ammonia. This ammonia is then used to make nitric acid, which is mixed to produce nitrate fertilizers. The energy requirements for this process are substantial, often relying on fossil fuels. Similarly, phosphorus- and potassium-based fertilizers are produced from mined ores, further contributing to the environmental impact of their production.
The production of synthetic pesticides also demands energy for the synthesis of various chemical compounds, including herbicides, insecticides, and fungicides. The extraction, transportation, and processing of raw materials, such as petroleum, contribute to the carbon footprint of these pesticides. The heavy reliance on fossil fuels in their production underscores the interconnectedness of the fossil fuel and agrochemical industries.
The advertising and business strategies employed by fossil fuel corporations in the pesticide market have contributed to the pervasive use of these chemicals in agriculture. This widespread adoption has led to significant environmental and social consequences, including biodiversity loss, toxic pollution, and negative impacts on human health. The close ties between the industries have also made industrial food production vulnerable to the volatility of oil and gas markets, as seen in the 2022 market shocks.
