Abstract

Este texto resenha as estimativas de curvas de custos marginais de abatimento - marginal abatement cost curves (MACC) - de gases de efeito estufa (GEE) para a economia brasileira, em particular para o setor industrial. Estudos sobre MACC de base tecnológica têm chamado a atenção de pesquisadores, uma vez que têm demonstrado uma quantidade significativa de possibilidades de mitigação com custo negativo de abatimento, o que implicaria oportunidades de mitigação sem custos diretos. Tal possibilidade motiva o debate sobre economia verde uma vez que a sua adoção poderia, inclusive, aumentar o crescimento. Então, inicialmente, apresenta-se a análise das curvas estimadas para o Brasil e, a partir delas, faz-se uma análise de sensibilidade para estimar parâmetros para discutir as opções de custo negativo. Finalmente concluímos que, apesar da existência de vieses de estimação, a mitigação de GEE no Brasil pode tirar grande proveito dessas opções de custos negativos. Palavras-chave: custos de abatimento de GEE; economia brasileira; setor industrial. This text review the current studies marginal abatement cost curves (MACC) of greenhouse gases (GHG) for the Brazilian economy, in particular for the industrial sector. Studies on technology-based curves has drawn attention of researchers since they have shown a significant amount of negative-cost abatement potential that would motivated the debate on green economy since growth could then increase if they were applied. So we first present the review of the estimated curves for Brazil and, based on them, we make a sensitivity analysis of estimating parameters to discuss the negative cost options. Finally we conclude that, despite the existence of estimation biases, GHG mitigation in Brazil can take advantage of low and negative cost options. Keywords: GHG abatement costs; brazilian economy; industrial sector.
