EX-ACT (Ex Ante Appraisal Carbon-balance Tool) was jointly developed from three FAO divisions (Policy and Programme Development Support Division [TCS] formerly Policy Assistance and Resource Mobilization Division [TCA], Investment Centre Division [TCI] and Agricultural Development Economics Division [ESA]). It is aimed at providing ex-ante estimations of the impact of agriculture and forestry development projects on GHG emissions and carbon sequestration, indicating its effects on the carbon balance.

Main outputs

It computes the C balance with and without the project. The difference represents the benefits of the project and indicates the net amount of C sequestered (C sink) as a result of the project.

It shows if the project is able to supply environmental services in the form of C sequestration, thus contributing to climate change (CC) mitigation.

Outputs could be used in financial and economic analysis of the project, guiding the project design process and the decision-making on funding aspects.

EX-ACT could therefore help project designers to select the project activities which have higher benefits both in economic and CC mitigation terms (added value of the project).

The obtained results put forward the multiple benefit of carbon as public good: value to farmer, value to community, value to society.

Targets of EX-ACT

EX-ACT has been tested especially on agricultural development projects and investment programmes. Ongoing tests on forestry projects are in progress, as well as value chains analysis.

 

Main characteristics of the tool

 

Ex-ACT in few words

  • Set of linked Microsoft Excel sheets (19)
  • Based on land use and management practices
  • Using IPCC* default values (Tier 1) and/or ad hoc coefficients (Tier2)
  • Measuring the benefits of an investment project/programme
  • Comparison of a situation without project and with project
