This paper analyses the decision to invest to reduce the emissions of a stock pollutant under environmental uncertainty. It shows that this decision depends on the type and level of uncertainty. When uncertainty is small, there is no simple irreversibility effect because of the tension between environmental irreversibility (the stock of pollutant causes costly long-term social damages), and inv...
