Given the urgency and the magnitude of emission cuts required to arrest the global temperature rise at an acceptable level (like 2 degrees Celsius), it is imperative that action to mitigate climate change is taken at the lowest cost. This can be done if a cost effective set of policy tools with a focus on carbon pricing is applied as broadly as possible across all emission sources. In view of the emerging consensus on the temperature target like 2 degrees Celsius, it is imperative that climate scheme caps global emissions rather than allowing governments to arbitrarily pledge their intended cuts. Global emissions must be contained within the limit of carbon budget that achieves temperature objectives. Emission allowances must be issued in accordance with such limit and be sold to the global demand of emitters. Such sales of carbon budget give rise to both the most accurate carbon pricing as well as new revenue that can be used for much needed climate financing for developing countries. A new climate regime along those lines would stop global warming at an acceptable level, provide a new large climate funding that would integrate developing countries to a global low-carbon growth and transformation and keep all economies thriving, whether they are developing, emerging or developed. The post-2020 climate regime must be nimble and effective, not unwieldy and least burdensome. It must also be durable and fully congruent to the economic realities of the coming decades.
