Agribusiness encompasses activities of extreme importance to society, such as food pro- duction. However, such activities generate risks and uncertainties due to the great impacts caused on the environment. Thus, the objective of this research is to measure the economic and environmental importance of agribusiness for Brazilian states. For this, the impor- tance for each state is measured; income is quantified; the most important aggregate is identified and the consumption of energy from renewable and non-renewable sources and electricity and the emissions of CO2 are determined. In order to capture the magnitude of agribusiness effects in each Brazilian state, it was used the input-output methodology with the inter-regional matrix for the year 2013. It was found that the agribusiness GDP corresponded to 19.4% of the national total, with Mato Grosso being the state that most depends on agribusiness (54.7%) for its economy. The agro-services aggregate proved to be the most important in agribusiness with 46.7% of Brazilian agribusiness GDP. The energy incorporated by agribusiness was 19.2 million toe of non-renewable energy, 42.5 million toe of renewable energy and 8.8 million toe of electricity. Emissions of CO2 reached 198, 154.7 Gg, with emphasis on the state of Amazonas, which was the least efficient, both in energy consumption and in CO2 emissions by agribusiness.
