The EX-ACT tool is an appraisal system which provides estimates related to the impact of agriculture and forestry development projects, programmes and policies on the carbon-balance.
EX-Ante Carbon-balance Tool (EX-ACT) for value chainsPDF
Mainly used for simple value chains in developing countries, EX-ACT VC is a multi-agent based tool appraising input supply, production, transport, processing and using numerous indicators.
This tool gives users an overview of emissions and trends in the agriculture, forestry, and other land use (AFOLU) sector for user-specified countries. It also contextualizes emissions within respective region(s), continent(s) and the world. This information can support countries preparing...
Quality assurance/Quality control (QA/QC) and verificationWebsite
The Quality assurance/Quality control (QA/QC) and verification tool allows users to compare national greenhouse gas (GHG) inventory data for the agriculture, forestry, and other land use (AFOLU) sector as reported to the UNFCCC with data from the FAOSTAT emissions database. The tool can help...
Global Livestock Environmental Assessment Model (GLEAM)Website
The global livestock environmental assessment model (GLEAM) is a modelling framework that simulates the interaction of activities and processes involved in livestock production and the environment. It is designed to analyse multiple environmental dimensions, such as feed use, greenhouse gas...
