ABSTRACT
This research presented a mathematical model to calculate the consumption of diesel oil and the
respective emissions of CO2 from 41 agricultural crops (38 permanent
and 3 temporary) in Brazil. It contains data obtained between 2000 and 2012,
from accredited bibliographic 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 growing species; (2) forest protection projects, with enrichment plantations; (3) implementation of agroforestry systems (1st cycle); and (4) urban afforestation projects (streets and parks). Such alternatives
are in line with the proposals of the “sectorial plan for mitigation and adaptation to climate change for the
consolidation of a low C emission in agriculture”, of the Brazilian Agricultural Research Corporation (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 products studied in this research. Therefore, in order to contribute to the reduction of the
release of CO2 into the atmosphere, perennial crops and
ecologically rational extractivism should be more encouraged and more supported
by the public authorities.
