What Is The Percentage Of Greenhouse Gases Due To Agriculture?

As the world grapples with the challenge of climate change, understanding the contribution of various sectors to greenhouse gas (GHG) emissions is crucial. Agriculture, often overlooked in discussions about emissions, plays a significant role in global GHG emissions. In this article, we will explore the percentage of global GHG emissions attributed to agriculture, backed by relevant statistics and facts. Recognizing the impact of agriculture on climate change is essential for developing sustainable farming practices and mitigating environmental damage.

  • According to the Food and Agriculture Organization (FAO), agriculture accounts for approximately 13.5% of global greenhouse gas emissions. This includes both direct emissions from agricultural activities and indirect emissions resulting from land-use change.
  • Livestock production alone is responsible for nearly 14.5% of global GHG emissions, according to the FAO. Methane emissions from enteric fermentation and manure management, as well as nitrous oxide emissions from manure and fertilizers, contribute significantly to this figure.
  • Deforestation associated with agriculture contributes to approximately 10% of global GHG emissions, according to estimates from the Intergovernmental Panel on Climate Change (IPCC). Land-use change, primarily for agricultural purposes, releases stored carbon dioxide and reduces the planet's capacity to absorb CO2.

Understanding Agriculture's Role in Greenhouse Gas Emissions:

Livestock Production: Livestock farming, particularly the rearing of ruminants like cows, contributes to significant GHG emissions. Methane, a potent greenhouse gas, is produced during the digestive process of ruminant animals. Additionally, manure management and enteric fermentation contribute to nitrous oxide emissions.

Deforestation and Land Use Change: The expansion of agricultural land, often at the expense of forests and other natural habitats, is a significant driver of GHG emissions. Deforestation releases large amounts of stored carbon dioxide (CO2) into the atmosphere, contributing to global warming and harming native biodiversity.

Synthetic Fertilizers and Nitrogen Cycling: The use of synthetic fertilizers in agriculture contributes to nitrous oxide emissions. Nitrogen-based fertilizers undergo processes that release nitrous oxide, a potent greenhouse gas, into the atmosphere. Furthermore, poor management of fertilizers leads to nitrogen runoff, contributing to water pollution and further emissions.

Mitigating Agriculture's Impact on Greenhouse Gas Emissions:

Sustainable Land Management: Promoting sustainable land management practices, such as agroforestry, alternative power sources, and conservation agriculture, can help reduce deforestation and enhance carbon sequestration in soils, mitigating emissions.

Precision Farming: Implementing precision farming techniques, including optimized fertilizer application and improved livestock management practices, can reduce the use of synthetic fertilizers and mitigate nitrogen emissions.

Agroecology and Organic Farming: Shifting towards agroecological and organic farming methods can help reduce GHG emissions associated with synthetic inputs, promote biodiversity, and enhance carbon sequestration in soils.

Improved Livestock Management: Adopting practices that focus on efficient feed conversion, improved animal genetics, and better manure management can help reduce methane emissions from livestock production.


Agriculture's contribution to global greenhouse gas emissions cannot be ignored. Livestock production, deforestation, and the use of synthetic fertilizers all contribute to the sector's environmental impact. Acknowledging these statistics and facts is crucial for developing strategies to mitigate emissions and foster sustainable agricultural practices. By promoting sustainable land management, precision farming, agroecology, and improved livestock management, we can reduce the percentage of global greenhouse gas emissions attributed to agriculture, helping combat climate change and build a more sustainable future.
