Résumé
Climate change poses an existential threat. Theoretical and empirical research suggest that carbon pricing and green R&D support are the right tools, but their implementation can be improved. Other policies, such as standards, bans, and targeted subsidies, also all have a role to play, but they have often been incoherent, and their implementation is delicate.
