Fossil fuels are severely damaging our environment and are the biggest driver of climate change. They cause local pollution where they are produced and used, and their ongoing use is causing lasting harm to the planet's climate. Food systems account for at least 15% of all fossil fuels, and the energy intensity of this stage is increasing as supply chains get longer, requiring increased packaging and stricter processing requirements. In industrial agriculture, crops are dependent on large amounts of nitrogen fertilizers, petroleum-based agricultural chemicals, pumps that run irrigation, diesel for machinery, and oil for food distribution across the world. The future for farming and agriculture holds many challenges, including the continued efforts to optimize energy inputs and reduce greenhouse gas emissions.

Fossil fuels are used to produce nitrogen fertilisers, agricultural chemicals, and run irrigation pumps
Fossil fuels are used extensively in commodity farming, and this heavy reliance has detrimental effects on the environment. Fossil fuels are used to produce nitrogen fertilisers, agricultural chemicals, and run irrigation pumps.
Nitrogen fertilisers are a key example of how fossil fuels are used in commodity farming. Nitrogen is one of the essential mineral nutrients that plants need, along with phosphorus and potassium. While in natural ecosystems, plants obtain nitrogen from animal manure and urine, decomposing plants, and other natural sources, the rise of industrial agriculture has led to a shift towards synthetic fertilisers. Nitrogen fertiliser is manufactured using fossil gas, and its production and use have increased significantly since World War II. The overapplication of synthetic fertilisers has led to environmental concerns, as excess nitrogen pollutes the air, water, and climate, contributing to biodiversity loss and ecosystem disruption.
Agricultural chemicals, such as pesticides, are also derived from fossil fuels. The use of these chemicals in industrial food production has led to toxic pollution and biodiversity collapse. Additionally, the close ties between agrochemicals and fossil fuels make food production vulnerable to fluctuations in the oil and gas markets.
Irrigation systems also contribute to fossil fuel usage in commodity farming. Since World War II, farmers on the High Plains have utilised centrifugal pumps, internal combustion engines, and advanced irrigation systems. These technologies require substantial fossil fuel energy to lift and distribute water, contributing to the depletion of non-renewable resources.
The use of fossil fuels in these aspects of commodity farming has led to increased greenhouse gas emissions, soil and water contamination, and negative impacts on biodiversity. There is a growing recognition of the need to transition towards sustainable farming practices, such as organic farming, agroforestry, and geothermal greenhouses, to reduce the environmental footprint of agriculture and move towards a cleaner and more sustainable future.
Overall, the production of nitrogen fertilisers, agricultural chemicals, and the operation of irrigation pumps are significant contributors to the use of fossil fuels in commodity farming, highlighting the urgent need for a transition to more sustainable practices.

The price of fossil fuels directly impacts the costs of tillage, fertilisers, and food prices
Fossil fuels are everywhere, and they are one of the main reasons humanity is in ecological overshoot. In industrial agriculture, crops are dependent on fossil fuels for large amounts of nitrogen fertilizers, petroleum-based agricultural chemicals, pumps that run irrigation, diesel for machinery, and oil for food distribution across the world. Food systems account for at least 15% of all fossil fuels. The price of fossil fuels directly impacts the costs of tillage and fertilisers, and food prices.
The availability and price of fossil fuels, such as oil, natural gas, and coal, influence the costs of agricultural production. The production costs of some agricultural commodities are more sensitive to changing fossil fuel prices than others. For example, in Slovenia, it takes 7 calories of fossil fuel to provide every 1 calorie of meat consumed. The number of fossil fuel calories varies by food group and country. The link between food and fossil fuel prices is complex due to the interaction between conventional agricultural feedstocks for food and energy markets.
If bioenergy becomes cheaper than fossil fuel inputs into agriculture, a rapid switch to on-farm bioenergy is likely to occur. This switch would depend on the strength of the linkage between energy and food prices, the demand for bioenergy feedstocks, and the impact of increased investment in bioenergy yields. Fossil fuel prices also influence the costs of agricultural production through the use of fossil fuel-based agrochemicals. A shift to agroecological production systems that use bio-fertilizers and on-farm pest management practices can help reduce the reliance on fossil fuels.
The future of farming and agriculture faces challenges in optimising energy inputs and reducing greenhouse gas emissions. Incentivising farmers to minimise agricultural GHG emissions may lead to greater integration of forestry and woody biomass cultivation on farms. The cultivation of perennial biomass crops can help balance GHG-intensive activities with carbon credits from enhanced carbon storage in soils. The transition to an all-renewable energy system is not simple, but it is necessary to address climate change and move towards net-zero emissions.

Fossil fuel companies have a vested interest in maintaining the status quo of fossil fuel-dependent agriculture
The highly mechanised farming practices associated with intensive food systems are dependent on fossil fuels, meaning that agribusiness and the petrochemical industry are profoundly linked. Food-related plastics and fertiliser account for 74% of petrochemical production, and the IEA predicts that by 2050, petrochemical usage will account for half the growth of the oil industry. This means oil businesses have a vested interest in perpetuating dependency on these products. The fossil fuel industry has been accused of perpetuating the climate crisis, with some companies accelerating their extraction of coal, oil and gas, despite the devastating impact on the planet and humanity.
The fossil fuel industry has used its lobbying group, the Global Climate Coalition, to stress the uncertainties of climate science. Fossil fuel companies have a responsibility for knowingly perpetuating the carbon era and accelerating the climate crisis. Fossil fuel use is the biggest driver of climate change, and it is clear that reducing emissions is necessary to avoid catastrophic breakdown. However, reducing emissions represents a direct threat to the profits of fossil fuel companies, and they are working on industry responses to the climate crisis, rather than reducing their extraction.
The link between fossil fuel companies and agriculture is clear, with fossil fuel-based fertilisers and pesticides integral to modern farming. Fossil fuel prices directly affect the costs of tillage and fertilisers and almost all aspects of agricultural production. Fossil fuel companies have a vested interest in maintaining this status quo, as do the agri-food sectors, which are dominated by a few firms with a vested interest in maintaining the current system. These companies make significant political contributions to ensure their influence.
The future of agriculture and farming holds many challenges, including reducing greenhouse gas emissions and improving yields to feed a growing global population. These challenges will be influenced by the availability and price of fossil fuels, as well as policies to meet carbon emissions targets. Fossil fuel-dependent agriculture is heavily subsidised by cheap and versatile fossil fuel, and it will be difficult to move away from this.

Fossil fuels are used for the transportation of food from the farm to the store
Fossil fuels are integral to the modern food system, from production on the farm to the point of purchase by the final consumer. The use of fossil fuels in the transportation of food from the farm to the store is a significant component of this.
The distance that food travels has increased by a quarter over the last two decades, escalating emissions. This transportation of food relies on fossil fuels, with oil being used for food distribution across the world. The energy intensity of this stage is increasing as supply chains get longer, requiring increased use of packaging and stricter processing requirements.
The use of fossil fuels in food transportation is further exacerbated by the use of energy-intensive equipment, refrigeration systems, and packaging to ensure the preservation of food. In high-income countries, retail is particularly energy-intensive due to higher consumption of processed foods and refrigeration requirements.
The transition to renewable energy sources for food transportation is a key aspect of mitigating the environmental impact of the food system. However, this transition is complex and influenced by various factors, including the availability and price of fossil fuels, policies aimed at reducing carbon emissions, and the adoption of renewable alternatives.
Overall, the transportation of food from the farm to the store is a significant contributor to the use of fossil fuels in the food system, and efforts to reduce this reliance are crucial in addressing the environmental and sustainability challenges faced by the agricultural sector.

The transition to renewable energy in agriculture is challenging due to the concentrated energy provided by fossil fuels
Fossil fuels are heavily used in agriculture, and this dependence on cheap and versatile fossil fuels has led to a high level of embedded energy in our food. In some cases, there are more "fossil fuel calories" than nutritional calories in the food we eat. For example, in Slovenia, it takes 7 calories of fossil fuel to provide every 1 calorie of meat consumed. Fossil fuels are used in industrial agriculture for nitrogen fertilizers, petroleum-based agricultural chemicals, pumps for irrigation, diesel for machinery, and oil for food distribution.
Secondly, the complexity of the interactions between conventional agricultural feedstocks for food and their use for energy makes this transition challenging. The price threshold for switching to bioenergy production is difficult to estimate due to the global oil market's influence. Additionally, the strength of the linkage between energy and food prices, the demand for bioenergy feedstocks, and the impact of increased investment in bioenergy yields can affect whether the switch to bioenergy production is competitive or synergistic with food production.
Thirdly, the current food and energy policies are not aligned with the goal of reducing fossil fuel use. Fossil fuel industries have a strong lobby, and countries that rely heavily on fossil fuel production are often reluctant to implement the necessary policies. There is also a lack of incentive-based policies to encourage the transition to renewable energy in agriculture, especially in lower-income countries.
Finally, the challenges of implementing renewable energy in agriculture vary between developed and developing countries. Renewable energy technologies well-suited to developed countries may not be suitable for developing countries due to technical and economic challenges. Therefore, the transition to renewable energy in agriculture is a complex process that requires addressing technical, economic, and policy barriers, as well as considering the specific contexts of different countries.
