The present research was developed with the objective of determining the consumption of the diesel oil in the production of cereals and fruits; assess the consequent amount of CO 2 emitted into the atmosphere; and, in addition, list forest projects that, through photosynthesis, during tree growth cycles, can contribute to the total or partial sequestration of these emissions.41 crops were selected: 38 perennials and 03 temporary, for which were rescued production data from 13 consecutive years, from 2000 to 2012.Thus, with the resulting mathematical model, it was possible to obtain CO 2 emissions from all crops -individual or grouped -, as well as to compare the results of perennial and temporary plantations.The selected study case show, for example, a comparation the diesel consumption and the respective CO 2 emissions of the crops: BANANA (Musa sp.) and SOYBEAN (Glycine max), based on the Brazilian production.About regarding the sequestration of carbon (C) four forest mitigation alternatives were elaborated: i) FOREST PROTECTION PROJECT; ii) REFORESTATION with fast growing species; iii) AGROFLORESTAIS SYSTEMS (1st cycle); and (iv) URBAN ARBORIZATION PROJECT.For each option, there is the indication of the numbers of trees to be planted or hectares to be protected/ enriched for a purpose of the total or partial reduction of the quantity of CO 2 issued for atmosphere.
