This proposal aim to estimative the greenhouse gas emissions (CO2, CH4 and N2O) and ammonia volatilization in broiler production and to compare the environmental charges of conventional and organic farming systems. The GHG sources that will be evaluated include nitrogen fertilization related to feed grain production, poultry litter, and other gases from fossil fuel consume and use of electricity. Using such information will be able to evaluate the greenhouse gas net used to produce one kilogram of chicken meat in conventional and organic systems, considering the same carcase weight. In order to obtain mentioned information, measurements for each component will be taken under field conditions in poultry sheds located at São Paulo State. Such measurements include the use of incubation chambers and gas analysis by gas chromatography which will be analyzed at CENA-USP. The results will be statistically treated by mean tests (Tuckey), variance (ANOVA) and correlation (Pearson Correlation). These results may help decision makers developing public policies aimed at reducing GHG emissions towards sustainability in beef production in Brazil. We believe that the products of this research are likely to collaborate with the newly created program "Low Carbon Agriculture (ABC)". This is important for the Brazilian poultry industry that, to remain competitive in the global marketplace must prove sustainable environmental performance.
