We measure the gains from phasing out coal as the social cost of carbon times the quantity of avoided emissions. By comparing the present value of avoided carbon emissions to the present value of the costs of ending coal plus the costs of replacing it with renewable energy, our baseline estimate is that the world could realize a net total gain of 77.89 trillion US dollars. This represents around 1.2% of current world GDP every year until 2100. The net benefits from ending coal are so large that renewed efforts, carbon pricing, and other financing policies, should be pursued.
The main result of the paper can be explored in this page. Additionally, you can explore the climate financing needed to phase out coal by country or region, or as an annual timeseries. Feel free to pick your own parameters to generate the results (the parameters are set to the baseline settings of the paper by default).
