Carbon pricing policies are adopted in many countries around the world to mitigate climate change. This systematic review shows that significant emission reductions of between 5 and 21% are achieved by at least 17 out of 21 reviewed policy schemes.
Global public expectations for carbon removal governance are: engagement beyond acceptance research; regulating industry beyond incentivizing innovation; systemic coordination; and prioritizing underlying and interrelated causes of unsustainability.
The 15th Conference of the Parties (COP15) in Copenhagen marked an important step in global climate action with parties submitting 2020 mitigation targets. However, this retrospective study shows that many countries either have failed to meet their targets or have reduced their emissions through carbon leakage.
Development ramifications of global decarbonization efforts for fossil fuel-producing low and lower–middle income countries remain underexplored. This Perspective suggests three transition pathways for navigating these ramifications.
Technological feasibility and project-level economic costs are only two important considerations in previous estimations of climate mitigation costs. Now a study shows how political and institutional constraints matter too.
Recent policy progress in the United States shows how populism can help advance climate goals, but at a steep cost. Avoiding setbacks will require curbing protectionist reflexes and harnessing opportunities for global cooperation.
Policies and subsidies can help, and have helped, to establish the electric vehicle market. As subsidies are withdrawn and policies shift, the public will play a role in the future market infiltration.
