EX-ACT: EX-Ante Carbon balance Tool


Summary report, presentations and exercises from SIANI/FAO Workshop: …

Summary report, presentations and exercises from SIANI/FAO Workshop:
“Discover new Opportunities with the Ex-Ante Carbon Balance Tool”

7-8 December 2011, Stockholm
Main workshop objectives:

Presenting the tool and spreading its usage
Assessing the needs/demand related to CC mitigation for further development of the tool
Building partnerships

The Ex-Act tool:

The tool is a multi-functional software. Ex-Act has the capability to perform, amongst others, Carbon Footprint Analysis, illustrating which agricultural and forestry activities are CO2 emitters or Carbon sinks.
The results can be used to measure and manage environmental impact and for communication purposes.

  • 1. EX-Ante Carbon-balance ToolBy Louis Bockel, Madeleine Jönsson, Ophélie Touchemoulin, FAO (TCSP)3-4 October 2011

  • 3. Why the development of EX-ACT?
  • 4. A partnershipPartnershipFAOInvestment Centre TCIPolicy support service TCSEconomic division ESAIRD (French DevelopmentResearch Institute)WBGIZ, IFAD, AFD (France), ADB, SEI(Sweden), ADEME (France) EX-ACT is a FAO tool to estimate the mitigation impact ofagricultural and forestry projectsExternal partnership and helps decision-making within agriculture and forestryplanning policies and investment projects
  • 5. The need of a new simple toolLack of tools that would help project designers to integrate significant climateresponse activities in AFOLU* sectors.Lack of operational toolsTools under UNFCCC/KPTool=Flowchart+Equations+Default values*AFOLU: agriculture, forestry and land use
  • 6. The need of a new simple toolLack of tools screening the whole agricultural sector
  • 7. The need of a new simple toolNeed for an acceptable method which:measures C-balance impact within ex-ante appraisal,complements usual economic analysis,and fits within the time constraints of formulation process.SimplePracticalCost effectiveUpgradableovertimeInformation that :-scientists can quantify/use,-farmers/project developerscan understand/useUp-scaling(Able to extrapolate to region,watershed and communitybasis)

  • 10. The Role of EX-ACTTakes into account activitiesthat impact GHG fluxes (emissions and sinks)Deforestation, A-Re/forestation, forest degradation, Restoration of grasslands, livestock, cultivation of annualcrops, cultivation of perennial crops, fertilization of crops, installation of building, installation of irrigation systems...CO2, CH4, N2Ofrom and to different poolsabove-ground biomass, below-ground biomass, soil, litter and dead woodEMISSIONS  STOCKS Positive result : There are more emissions Negative result: There are less emissions MITIGATION !Carbon balance in t of eq-CO2
  • 11. The carbon balance, for a specific project (or scenario of action) in comparison witha reference, should be considered as the net balance of all GHG emissionsexpressed in CO2 equivalent (sources and sinks) with the atmosphere interface andthe net change in C stocks (biomass, soil…).Future without project100 ha flooded rice100 ha degraded pastures100 animalsFuture with project100 ha improved irrig. rice100 ha restored pastures100 High productivity animals?more or lessGHG released?The Role of EX-ACT

  • 16. • It computes the C balance with and without the project. The differencerepresents the benefits of the project and indicates the net amount ofC sequestered (C sink) as a result of the project.• It illustrates weather the project is able to supply environmentalservices in the form of C sequestration, thus contributing to climatechange (CC) mitigation.• Outputs could be used in financial and economic analysis of theproject, guiding the project design process and the decision making onfunding aspects• EX-ACT could therefore help project designers to select the projectactivities which have higher benefits both in economic and CCmitigation terms (added value of the project)• Put forward the multiple benefit of carbon as public good :Value to farmer, Value to community, Value to societyOutputs of the tool
