Technical guidelines
 

Objectives

The objective of the technical guidelines is to describe the structure of the Ex Ante Carbon-balance Tool (EX-ACT); to provide a detailed scientific background in order to fully understand the logic of the model. The guidelines also provide a few examples, demonstrating and explaining the calculations made in EX-ACT.

Summary

EX-ACT is a land-based accounting system, measuring carbon stocks, stock changes per unit of land, and CH4 and N2O emissions expressed in ton equivalent-CO2 per hectare and year.

The main output of the tool is an estimation of the carbon balance associated with the adoption of alternative land management options, compared with a 'business as usual' scenario.

The IPCC 2006 guidelines for National Greenhouse Gas Inventories, as well as other existing methodologies and reviews of default coefficients, underpins the development of the EX-ACT tool. Default values for mitigation options in the agricultural sector are mainly from the 4th assessment Report.
