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.

技术效率提高对温室气体排放的作用：对巴西甘蔗生产的分析

本文旨在研究技术效率提高对减少巴西甘蔗生产中温室气体排放的贡献，并估计生产者应获得的货币补偿以减少污染。利用产出距离函数及其与收入函数的对偶性，我们估计了巴西各城市甘蔗生产的技术效率以及减少这种作物生产中二氧化碳排放的影子价格。主要结果是总体技术效率平均为81%，这表明如果生产者采取更好的管理措施，甘蔗产量可以扩大19%，二氧化碳排放量也可以减少相同幅度。我们还估计，每吨二氧化碳的影子价格平均为9.18雷亚尔，其中南马托格罗索州、帕拉巴州、马托格罗索州和巴伊亚州的影子价格最高。然而，在最具代表性的全国二氧化碳生产商圣保罗州，影子价格估计为每吨6.34雷亚尔。在这个意义上，公共政策，特别是通过公共筹资和公共技术援助，可能在短期内减轻生产者的损失，因为减少污染通常需要更多的机械化。

期刊介绍： Agribusiness: An International Journal publishes research that improves our understanding of how food systems work, how they are evolving, and how public and/or private actions affect the performance of the global agro-industrial complex. The journal focuses on the application of economic analysis to the organization and performance of firms and markets in industrial food systems. Subject matter areas include supply and demand analysis, industrial organization analysis, price and trade analysis, marketing, finance, and public policy analysis. International, cross-country comparative, and within-country studies are welcome. To facilitate research the journal’s Forum section, on an intermittent basis, offers commentary and reports on business policy issues.
