Japan has pledged not to start building any more unabated coal-fired power plants at home, adding to international efforts aimed at curbing the largest source of global emissions.

¡°In line with its pathway to net zero, Japan will end new construction of domestic unabated coal power plants, while securing a stable energy supply,¡± Prime Minister Fumio Kishida said Friday at the COP28 summit.

Decisions by other nations on the issue ¡°should be addressed by each country in the course of the respective pathways to net zero, reflecting national circumstances,¡± he said.
