Our Food System Is the Bullseye for Solving the World’s Climate Challenges
While transportation and electricity production are often in the spotlight when considering greenhouse gas emissions, the industrialized food system is also a major source of emissions, making it a critical topic to address.
According to the Environmental Protection Agency (EPA), the agriculture sector accounts for 10 percent of total U.S. greenhouse gas emissions, ranking second after transportation. However, the EPA estimate underestimates the true impact as it fails to consider important sources of emissions such as soil carbon, lost sequestration, input footprints, difficult measurements, and potent gases like methane and nitrous oxide.
Methane and nitrous oxide, emitted in large amounts by agriculture, have even greater warming potential than carbon dioxide. Methane, released by ruminant animals like cows, has up to 86 times more global warming potential over a 20-year period than carbon dioxide. Nitrous oxide, a byproduct of fertilizer runoff, is 300 times more potent. Other studies, including those by the United Nations, suggest that agriculture's contribution to global greenhouse gas emissions is closer to 15 or 20 percent.
At COP27, the 2022 UN Climate Change Conference, governments intensified efforts to reduce greenhouse gas emissions and enhance adaptive measures in the agriculture sector. An important milestone was achieved with the establishment of a comprehensive four-year plan addressing agriculture and food security. This plan aims to mobilize increased financial resources to drive transformative changes in the agricultural sector by 2030. Additionally, the Food and Agriculture for Sustainable Transformation (FAST) initiative was launched, led by over 20 agriculture ministers and the Egyptian COP27 presidency.
Shifting to plant-based agriculture offers a more sustainable and efficient approach, as animal farming is known for its inefficiencies and waste. Transitioning to plant-based diets not only reduces emissions but also helps prevent food shortages and hunger exacerbated by climate change. Climate-related events, such as heatwaves and droughts, disproportionately impact food-insecure populations. The United Nations Environment Program emphasizes the need to reduce cattle-based food consumption and food waste while promoting plant-rich diets.
Addressing the broken global food system is crucial to combatting the climate crisis. Transitioning to sustainable practices, reducing meat consumption, and prioritizing food security are essential steps toward building a resilient future. By embracing change at all levels, individuals, communities, and governments can contribute to a more sustainable and climate-resilient food system.
