Abstract

Este trabalho avalia o conceito de equidade intergeracional na avaliação ambiental de projetos com impactos no longo prazo no que tange à determinação da taxa de desconto. São analisados os conceitos de equidade intergeracional na Economia e as formas encontradas para incluir esse aspecto na definição da taxa de desconto utilizada na mensuração econômica dos custos ambientais com impactos no longo prazo. As propostas apresentadas por Padilla (2002) e a aplicação da Fórmula de Ramsey com segurança equivalente são adotadas na análise. As análises conduzidas apontaram que há uma diferença significativa na adoção da taxa de desconto dita sustentável em comparação com a de mercado no caso brasileiro. Algumas sugestões em termos de tomada de decisão são apresentadas no final.
