    If we want to apply the ACB methodology to the problem of global warming we find serious difficulties as how to obtain the correct data, how to use the Gross Domestic product (GDP) , the use of the discount rate and the uncertainty. One of those uncertainties is that the scientists do not know exactly which are the key factors that produce the climate change. This point makes many experts think that it is necessary to implement immediate actions that mitigate global warming. The problem is that ACB cannot deal with this argument. This paper discusses what are the difficulties of ACB methodology in order to be applied to climate change. A la hora de aplicar la metodología del análisis coste-beneficio (ACB) al fenómeno del calentamiento global nos encontramos ante una serie de complicaciones tales como la obtención correcta de los datos, la utilización del producto nacional bruto (PNB), el uso de la tasa de descuento y la incertidumbre. Una de las incertidumbres es que, todavía los científicos no entienden algunos de los mecanismos claves que determinan el cambio climático, por lo que la opinión de muchos expertos es la de poner en marcha acciones inmediatas encaminadas a mitigar el calentamiento global. El problema es que este argumento es difícil de incorporar en el ACB. En este artículo se exponen las dificultades que existen para aplicar la metodología ACB al problema del cambio climático.
