Given the media spotlight on global warming and El Nino, Koutstaal (Netherlands Energy Research Foundation ECN) presents a timely, data-based model of the economic impact of climate change. He advocates an international strategy of employing economic leverage to limit the 25% increase in CO2, the main greenhouse gas, since the mid-18th century. While research on the economic instrument of tradable emission permits (TCPs) is presented here, the salient focus is on designing a viable system of TCPs, and comparing the environmental/economic consequences of such a system simulation with other options (e.g. taxes).
