“The average annual additional costs are ~0.62% of China’s GDP in 2020. It is a large but manageable value, especially recognizing that it does not account for the considerable external co-benefits of fossil fuel substitution, such as reduced health and agricultural damages from air pollution.” IMAGE@Cost increase in the electricity supply to achieve carbon neutrality …
