Global | Climate Policies Effectiveness: What Works Best?

Summary

Climate policies have reduced emissions and advanced low-carbon technologies but still fall short of meeting global goals. Achieving the transition toward decarbonization requires effective, context-specific policy mixes, with carbon pricing well-coordinated with subsidies and regulations playing a key role.

Key points

• Key points:
• Climate Policies' Impact: Climate policies over recent decades have successfully reduced greenhouse gas emissions and promoted advancements in low-carbon technologies. However, these policies still fall short of bridging the emissions gap needed to meet global climate goals.
• Effectiveness of Policy Mixes: Well-designed and context-specific combinations of policies, such as carbon pricing, subsidies, and regulations, are significantly more effective in reducing emissions than standalone measures.
• Regional and Sectoral Disparities: The effectiveness of policies varies across regions and sectors, with developed economies benefiting more from market-based instruments like carbon pricing, while developing regions face challenges due to limited data and resources.
• Need for Ambitious and Adaptive Policies: Urgent, adaptive, and inclusive policymaking is essential to address regional disparities, scale up best practices, and close the emissions gap. Improved monitoring and evaluation mechanisms are critical to enhancing policy effectiveness globally.
