Across carbon pricing schemes, we find that on average the policy has reduced emissions by –10.4% [95% CI = (–11.9%, –8.9%)].
Contexto
What changed: Implementation of explicit carbon pricing policies, encompassing cap-and-trade systems and carbon taxes. Comparison: Counterfactual emissions pathways without carbon pricing, estimated using quasi-experimental methods. Limits: Carbon price levels were low in most evaluated jurisdictions, and about 46% of primary studies had a medium or high risk of bias.
