Abstract The paper examines the issue of international pollution control under a dynamic framework involving heterogeneous countries and a critical threshold. We propose an appealing specification for this type of problem, and its novelty is illustrated by the fact that countries use linear strategies in equilibrium, although their utility and damage functions are highly convex. The stock of pollution under cooperation is always lower. Surprisingly, emissions are always higher in distant periods under the cooperative scenario; and we show through examples that this is a significant finding rather than some marginal effect. It is also shown that the efficient allocation of pollution abatement is driven only by the respective technologies of the countries. Finally, a dynamic transfer scheme allowing to implement the cooperative solution is proposed.
