Methods for estimating Greenhouse gas emissions

Mitigation potential

By generating and sharing greenhouse gas data, the MICCA Programme contributes to an improved understanding of the potential for greenhouse gas emissions and removals from the agriculture, forestry and other land use changes (AFOLU) sector.

 MICCA’s work in this area:

  • helps to identify emission hotspots in AFOLU, as well as economically viable and sustainable practices and methods to mitigate climate change, while increasing the resilience of agricultural systems
  • facilitates the integration of climate change mitigation into agricultural, forestry and land management policies and practices
  • guides the way to rational investments in improved technologies and agricultural practices.

Tools to assess mitigation potential

  • Life cycle assessments (LCAs)
    The quantification of greenhouse gas emissions arising from the entire agricultural production chain. MICCA team members have developed a methodology to quantify GHG emissions arising from animal food chains. This methodology makes it possible to calculate how much GHG is emitted, along the entire production chain, for products such as milk, meat and eggs. The work continues on five crops.  

  • Marginal Abatement Cost Curves.
    Practices for enhancing soil carbon stocks were assessed using DayCent, a biophysical model that simulates fluxes of carbon and nitrogen in the atmosphere, vegetation and soil. This modelling work was conducted in collaboration with Colorado State University. The outputs from this biophysical model were combined with economic information to develop a global set of Marginal Abatement Cost Curves (MACCs) for agriculture. 

  • EX ACT tool for Ex-ante carbon-balance analysis. The tool is an appraisal system developed by FAO providing ex-ante estimates of the impact of agriculture and forestry development projects, programmes and policies on the carbon-balance. MICCA has contributed to the development of this tool.
