Examples of how The Ex Ante Carbon-balance Tool has helped people assessing the impacts of low-emission development strategies in countries and regions:
The model's website includes information on applications, publications and results validation.
"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."
"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."
