The CCAFS Mitigation Options Tool (CCAFS-MOT) estimates greenhouse gas emissions from various crops (e.g. barley, maize, sugarcane), crop groups (e.g. vegetables, legumes), and livestock production in different regions. CCAFS-MOT is distinct because it: (1)Ranks the most effective mitigation options for 34 different crops according to their mitigation potential, and in relation to current management practices and climate and soil characteristics; (2) Has low input data requirements, it only takes approximately 5 minutes to input data; (3) Runs in Excel; and (4) Is freely downloadable from the CCAFS website.
