Overview

This analysis finds carbon taxation can improve global welfare and reduce inequality, highlighting effective redistribution strategies.

  • Integrated Assessment Models reveal how climate policy can balance emissions mitigation and social justice concerns.
  • Implementation of effective revenue recycling mechanisms is crucial for achieving both environmental and social goals.
