Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

Sustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.
