The EX-Ante Carbon-balance Tool (EX-ACT)

The EX-Ante Carbon-balance Tool (EX-ACT) is based on the Intergovernmental Panel on Climate Change (IPCC) methodology for greenhouse gas (GHG) emissions inventories. EX-ACT provides its users a consistent way of estimating and tracking the outcomes of agricultural interventions on GHG emissions. EX-ACT is the only GHG accounting tool to cover the entire agricultural sector including Agriculture, Forestry and Other Land Use (AFOLU,) inland and coastal wetlands, fisheries and aquaculture, agricultural inputs and infrastructure.

EX-ACT aims at i) identifying the climate mitigation outcomes of agricultural interventions (projects, policies and investments) at any stage of their implementation (ex ante, during and ex post) and at any level (local, regional and national); ii) supporting countries (public and private sectors) in accessing funds from international financial institutions; iii) strengthening the capacities of national and international stakeholders in estimating, monitoring and evaluating progress on emissions reduction goals; and iv) support policy makers in integrating climate change mitigation objectives into national strategies and international commitments, such as Nationally Determined Contributions or National Adaptation Plans.

  • Proposes IPCC default values (Tier 1) and allows for including location-specific coefficients (Tier 2).
  • Allows to evaluate the additionality of the intervention.
  • Adapted to any scale (local, regional and national).
  • Applicable to any stage of implementation (ex ante, during and ex post).
