Abstract

Suele darse por sentado que la valoración de los impactos que recaen sobre las generaciones presentes no comporta dificultad alguna. Sin embargo esto no es cierto. Es más, no se dispone de una metodología ampliamente aceptada para contabilizar dichos impactos. Algunos de los aspectos más controvertidos son: la elección del valor apropiado para la tasa de descuento, las unidades -físicas o monetarias- en que deben expresarse los flujos y la valoración de los bienes tangibles e intangibles. Cuando existen impactos a muy largo plazo surge el problema de valorar los costes y beneficios que afectan a las generaciones futuras mediante, por ejemplo, una tasa de descuento intergeneracional. Incluso en este último caso estaría dominando la perspectiva de las generaciones presentes, que actuarían como si poseyeran la totalidad de los derechos de propiedad sobre todos los recursos. Por lo tanto es necesario incorporar el requisito de sostenibilidad en el análisis. En este trabajo se examinan algunos de estos aspectos y se proponen vías de solución.
