Abstract

This article aimed to investigate the contribution of technical efficiency gains to reducing the emission of greenhouse gases in Brazilian sugarcane production and to estimate the monetary compensation that producers should receive to reduce pollution. Using an output distance function and its duality with the revenue function, we estimated the technical efficiency of sugarcane production in Brazilian municipalities and the shadow price of reducing carbon dioxide (CO2) emissions from the production of this crop. The main result was an overall technical efficiency average of 81%, which indicates that if producers adopt better management practices, the sugarcane production could be expanded by 19% with a contraction by the same magnitude in CO2 emissions. We also estimated a mean shadow price of R$9.18 per ton of carbon dioxide, with the highest estimated values in the states of Mato Grosso do Sul, Paraná, Mato Grosso, and Bahia. However, in the state of São Paulo, the most representative national producer, the estimated shadow price is R$6.34 per ton of carbon dioxide. In this sense, public policies, especially through public financing and public technical assistance, could potentially mitigate the producers' losses in the short run since pollution decline usually requires more mechanization.
