摘要

This research presented a mathematical model to calculate the consumption of diesel oil and the respective emissions of CO2from 41 agricultural crops （38 permanent and 3 temporary） in Brazil. It contains data obtained between 2000 and 2012, from accreditedbibliographic sources. In addition to spreadsheets containing diesel consumption, resulting from the analysis of the productive processes,this research presents data on energy conversion and forest development used to subsidize CO2 emissions and mitigation options.Specifically for C sequestration of the atmosphere, four options of forest projects were systematized： （1） reforestation with fast growingspecies; （2） forest protection projects, with enrichment plantations; （3） implementation of agroforestry systems （1 st cycle）; and （4） urbanafforestation projects （streets and parks）. Such alternatives are in line with the proposals of the ＂sectorial plan for mitigation andadaptation to climate change for the consolidation of a low C emission in agriculture＂, of the Brazilian Agricultural ResearchCorporation （EMBRAPA）. The results show that three temporary products （soybean, sugarcane and cotton） are responsible, for at least,85% of all CO2 emissions, comparatively the low consumption of diesel oil verified in the management of the 38 permanent productsstudied in this research. Therefore, in order to contribute to the reduction of the release of CO2 into the atmosphere, perennial crops andecologically rational extractivism should be more encouraged and more supported by the public authorities.
