USAID Carbon Calculator
From Open Energy Information
This tool allows users to systematically estimate the CO2 benefits and consequent climate impacts of agriculture, forestry and other land use (AFOLU) programs worldwide. Emission reductions and removals can be quantified at the sub-national and project level for: forest protection, forest management, afforestation/reforestation, agroforestry, crop management and grazing management. (The Carbon Calculator was not developed under LEAF, but is a key reporting tool used by LEAF to estimate emissions avoided or removed).
