Reducing CH₄ and N₂O Emissions from Agriculture

Back to Agriculture

Agriculture accounts for approximately 10% of total global greenhouse gas emissions, including about 60% of global nitrous oxide (N2O) and 50% of methane emissions. The ineffective application and use of fertilizer is one major source of N2O emissions, where instead of being incorporated into crops the nitrogen fertilizer is broken down into N2O by soil bacteria; while methane emissions from rice cultivation is another major source of emissions. Together, these two emissions sources from farming account for 2.4% of global greenhouse emissions. Technology opportunities exist in precision agriculture for improved application of fertilizer and N2O production inhibitors, in addition to the development of advanced crop management techniques for rice production.
