Fossil fuels have had a significant impact on agriculture, with modern agricultural practices heavily reliant on fossil resources for crop management, fertilizers, pesticides, and machinery production. This dependence on fossil fuels has contributed to increased food production since the 1960s but has also led to challenges in optimizing energy inputs and reducing greenhouse gas (GHG) emissions. The costs of fossil fuels directly impact agricultural production, influencing the prices of tillage, fertilizers, and ultimately, the cost of food for consumers. With food systems contributing about 15% of all fossil fuel usage and a significant portion of GHG emissions, there is a growing need to transition to more sustainable and low-carbon agricultural practices. This includes promoting crops for biofuel, adopting renewable technologies, and shifting to agroecological production systems that reduce external inputs and prioritize environmental sustainability.

Fossil fuel prices directly impact farming costs and consumer food prices
The agriculture industry's dependence on fossil fuels is a critical issue. While agricultural demand for fossil energy is a relatively small share of the overall market, it is growing. As yields increase, so does the need for energy-intensive inputs, making agriculture increasingly dependent on fossil fuels. This dependence has a direct impact on farming costs. For example, a rise in diesel prices can significantly increase the cost of running machinery, which is then reflected in the price of the final product.
Policies aiming to reduce fossil fuel use in agriculture, such as the renewable transport fuels obligation (RTFO) and the renewables obligation (RO) in the UK, may help to mitigate the impact of fossil fuel prices on farming costs. Additionally, net soil carbon sequestration on agricultural lands has the potential to offset a portion of global GHG emissions and contribute to meeting the targets of the Paris Agreement. However, this should not be seen as a justification for the continued use of fossil fuels in agriculture.
The transition to sustainable agriculture and food production is a key focus of discussions at the United Nations Conference of the Parties on Climate Change (COP28). Philanthropies, donors, and policymakers all have roles to play in supporting and promoting healthy and sustainable food environments. By encouraging the phase-out of unnecessary fossil fuel inputs, such as single-use plastics and certain fertilizers, policymakers can help to reduce the impact of fossil fuel prices on consumer food prices.
Overall, the direct relationship between fossil fuel prices and farming costs highlights the importance of transitioning towards more sustainable and renewable energy sources in agriculture. By reducing the industry's reliance on fossil fuels, it may be possible to mitigate the impact of fuel price volatility on consumer food prices and contribute to global emissions reduction targets.

Fossil fuel use in agriculture contributes to climate change
Fossil fuel use in agriculture contributes significantly to climate change. Food systems account for at least 15% of all fossil fuel consumption, with industrial agriculture heavily reliant on fossil fuels for machinery, irrigation pumps, transportation, refrigeration, and the production and distribution of fertilizers and pesticides. This heavy dependence on fossil fuels has made agriculture a major contributor to greenhouse gas (GHG) emissions.
The combustion of fossil fuels in agriculture results in the emission of carbon dioxide (CO2) and other greenhouse gases. These emissions contribute to the warming of the planet, leading to climate change. While agriculture's share of the fossil energy supply market is relatively small and shrinking, the sector's growing demand for energy makes it increasingly dependent on fossil fuels. As a result, higher yields and the inputs required to support those yields have intensified this reliance.
The impact of fossil fuel use in agriculture extends beyond climate change. The production and use of fossil fuels contribute to soil degradation, water quality issues, and biodiversity loss. Additionally, the energy-intensive nature of industrial agriculture reduces the need for labor inputs, affecting employment in the agricultural sector.
To address these challenges, there is a growing emphasis on sustainable agriculture and food production. Policymakers and philanthropists are exploring ways to incentivize consumers to make better choices and support policies that phase out unnecessary fossil fuel inputs, such as single-use plastics and certain fertilizers. Net soil carbon sequestration on agricultural lands, for instance, has the potential to offset a portion of annual global human-induced GHG emissions and contribute to the goals of the Paris Agreement.
However, transitioning away from fossil fuel-dependent agriculture is complex. Powerful firms within the agri-food sector have vested interests in maintaining the status quo, investing significantly to influence policies and markets in their favor. Nonetheless, with collaborative efforts between the energy and food sectors, along with support from philanthropists and donors, there is an opportunity to optimize energy inputs, reduce GHG emissions, and promote sustainable practices in the agriculture industry.

Fossil fuel industry expansion impacts food systems
Fossil fuel expansion has a significant impact on food systems, with food production contributing heavily to the use of fossil fuels and, in turn, affecting climate change. The current global food system is heavily dependent on fossil fuels, which directly affect the costs of tillage and fertilizers and, indirectly, the prices of food for the end consumer. This relationship between energy inputs and yields is complex, with low-energy inputs sometimes leading to higher energy demands and increasing energy inputs resulting in smaller yield gains.
The fossil fuel industry's expansion plans threaten to further entrench this system. In the United States, the industry was projected to spend over USD 164 billion from 2016 to 2023 on new facilities and expanding petrochemical projects. Similarly, in the UAE, major producers have announced USD 150 billion in investments to accelerate oil and gas production. This expansion of fossil fuel use in food systems calls for an urgent shift to agroecological production systems that are less reliant on external inputs and more focused on environmentally friendly alternatives.
Agriculture and food systems are responsible for a significant portion of global emissions, contributing to around one-third of all emissions driving the climate crisis. This includes not only the direct energy use for crop management but also the indirect energy used for machinery and fertilizer production, as well as the degradation of soils, water quality, and biodiversity. With the growing global population, there is an urgent need to improve yields while also reducing greenhouse gas emissions.
To address these challenges, policies to reduce emissions from the fossil energy sector can impact agriculture in two ways. Firstly, by promoting crops for biofuel or bioenergy, and secondly, by influencing farming practices through GHG emission reporting requirements. Additionally, net soil carbon sequestration on agricultural lands could help offset global GHG emissions and contribute to meeting the targets of the Paris Agreement. However, this does not mean that agriculture should become an offset for fossil fuel producers, but rather a part of the solution, alongside the necessary phase-out of fossil fuels.

Fossil fuel use in agriculture degrades soil, water quality, and biodiversity
Fossil fuels are the dominant source of energy for agriculture, and their use in this sector has a detrimental impact on soil, water quality, and biodiversity.
The burning of fossil fuels releases nitrogen oxides into the atmosphere, which contribute to smog and acid rain. This excess nitrogen is deposited back onto the land and eventually finds its way into nearby water bodies. The result is pollution, harmful algal blooms, and oxygen-deprived aquatic zones. These issues are detrimental to aquatic life, with excess ammonia and low pH levels proving toxic to organisms. This is a particular concern as sources of nitrogen from human activities, including agriculture, can upset the natural balance of nitrogen in the environment.
The use of fossil fuel-based fertilizers in agriculture is a significant contributor to this issue. Nitrogen fertilizer is manufactured using fossil gas, and its overuse, along with climate change, degrades soils. Fields become more prone to erosion, and the living organisms in healthy soils are damaged, leading to a vicious cycle where farmers feel they need to use even more fertilizer. This is a global issue, with 20 excess nitrogen fertilizer "hot spots" across the US contributing to 63% of the nation's excess nitrogen.
The exploration and extraction of fossil fuels also have a direct impact on biodiversity. The conversion, degradation, and disturbance of habitats at extraction sites, as well as the increased accessibility they provide, all contribute to biodiversity loss. This is a concern as human society depends on the goods and services provided by biodiversity, such as food, fibre, and medicines.
To address these issues, there is a growing emphasis on adopting soil-protecting, pollution-reducing, and climate-friendly practices in agriculture. This includes sustainable farming practices that do not harm the environment, such as agroecology, which views farms as ecosystems rather than factories.

Policies to reduce fossil fuel emissions may impact farming practices
Fossil fuels have long been a dominant source of energy for agriculture, with direct energy uses in crop management and indirect uses in fertilizers, pesticides, and machinery production contributing to increased food production since the 1960s. However, recognizing the impact of the food system's contribution to climate change, policies to reduce fossil fuel emissions may have a significant impact on farming practices.
Firstly, policies may promote crops that can be used as feedstocks for biofuel or bioenergy, leading to the adoption of different growing regimes and more efficient energy inputs. This shift could be incentivized by reviewing existing electricity subsidies for biogas production and providing tax credits, subsidies, and loans for biofuel feedstock production. Additionally, with the recognition that food systems are a crucial part of the solution to the climate crisis, policies may aim to reduce greenhouse gas (GHG) emissions by implementing reporting requirements for biofuels, which could trickle down to affect farming practices and improve emissions across the supply chain.
Secondly, the availability and pricing of oil, natural gas, and coal will influence farming practices as the world transitions to more sustainable energy sources. The mix of fuels used in agriculture may change, as different crops have varying fertilization and cultivation requirements. For example, nitrogen fertilizer production is a significant user of natural gas and coal, accounting for over 50% of total energy use in commercial agriculture. As such, policies targeting carbon emissions and sustainability will impact the energy inputs and costs of agricultural production.
Furthermore, policies promoting renewable and low-carbon technologies in agriculture can bring multiple benefits. Implementing renewables-based technologies for cooling, heating, and drying agricultural products can lead to co-benefits with minimal resource requirements in a short timeframe. Additionally, net soil carbon sequestration on agricultural lands has the potential to offset a significant portion of annual global GHG emissions, contributing to the targets of agreements like the Paris Agreement.
While agriculture is part of the solution to reducing emissions, it cannot become an offset for the fossil fuel industry. The transition to sustainable agriculture and food production requires a collaborative approach by the energy and food sectors, as well as a shift in consumer choices. Moving away from fossil fuel-dependent agriculture involves recognizing the need to revolutionize how we produce and consume food, reducing our reliance on cheap and versatile fossil fuels.
