RT Journal Article SR 00 ID 10.1146/annurev-economics-051520-015113 A1 Blanchard, Olivier A1 Gollier, Christian A1 Tirole, Jean T1 The Portfolio of Economic Policies Needed to Fight Climate Change JF Annual Review of Economics YR 2023 FD 2023-09 VO vol.15 SP 689 OP 722 K1 climate change K1 carbon price K1 green R&D K1 carbon border adjustment K1 climate finance AB 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.
