Increasing climate ambition through 2030 will be crucial to limiting global peak temperature changes this century. Countries need to ratchet their 2030 pledges made in Glasgow to reduce temperature overshoot and consequently reduce the risks of irreversible and adverse consequences to natural and human systems.
Reforms are required to maintain a healthy and robust flood insurance market under future climate conditions for the United States. Therefore, policymakers should implement premiums that reflect flood risk and incentivize household-level risk reduction, complemented with regional flood adaptation investments.
Many companies purchase renewable energy certificates to report reduced emissions, but this may not lead to actual emission reductions. We need emission accounting that is both accurate and that incentivizes companies to make impactful contributions to decarbonizing electricity grids.
We find limited evidence that individual or household rebates (also called dividends) have increased public support for carbon taxes in Canada and Switzerland. In the presence of partisan and interest group conflict over climate policy, policymakers should not assume that voter support for carbon pricing will automatically increase with the inclusion of rebates.
