Furthermore, Western economists (since Adam Smith) have invented a unique liberal economic model with “perfect” market functioning and natural market driven solutions to societal issues that are supposed to satisfy needs through the introduction of technologies and products. More recent thinking, from Von Hayek to Friedman, advocates as little government intervention as possible. However, when considering climate mitigation and adaptation, we are faced with a classical “market failure” when no solution is yet “naturally” coming from the “invisible hand” of the market. For states and governments, it seems almost impossible to intervene and regulate at a planetary level while a large number of citizens and companies do not trust them to efficiently achieve a real reduction of climate change enhancing activities. A lot of bold leadership is needed here.
