    Abstract This paper evaluates the concept of intergenerational equity in the environmental evaluation of projects with long term impacts in relation to the determination of the discount rate. The concepts of intergenerational equity in the Economy and the ways found to include this aspect in the definition of the discount rate used in the economic measurement of the environmental costs with long term impacts are analyzed. The proposals presented by Padilla (2002) and the application of the Ramsey Formula with equivalent safety are adopted in the analysis. The analyzes conducted showed that there is a significant difference in the adoption of the discount rate, which is said to be sustainable compared to the market rate in the Brazilian case. Some suggestions in terms of decision making are presented at the end.

    Resumo 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.
