Sectoral Policies


Climate policies are multi-faceted: along with carbon pricing, multiple targeted sectoral policies are being launched. Carbon pricing is developing worldwide, notably via the implementation of markets for emission permits (Europe, California-Québec, China). These markets do not cover all emissions and the implementation of an economy-wide carbon price has proved difficult. Complementary policies include R&D subsidies, production subsidies (for renewable energies, electric vehicles, etc.), technical standards (e.g. the CAFE standards in the US transportation sector), among others. These policies aim at facilitating the transition towards a low carbon economy. Yet, whether they enhance or hinder the efficiency of climate policy is debatable. Critics say they constitute inefficient additions, if not substitutes, to carbon pricing; proponents, on the other hand, argue that they are necessary to make climate policy effective in the long-run. This research area will combine both approaches at the theoretical and applied levels.
