China is the world’s largest emitter of heat-trapping gasses by far. The Chinese government has ambitious policies to fight climate change, including a pledge to achieve carbon neutrality by 2060. China leads the world in deployment of renewable energy and electric vehicles, but also in coal consumption and the construction of coal-fired power plants. Last summer, China suffered a heat wave that several meteorologists described as the worst in recorded history, anywhere.
CGEP Inaugural Fellow David Sandalow and a team of co-authors have comprehensively updated his Guide to Chinese Climate Policy, exploring these issues and more. David Sandalow, Michal Meidan, Sally Qiu, and Edmund Downie discussed their new book, which includes eight new chapters on topics including the manufacturing sector, clean energy R&D, and the food system. The discussion is especially timely, with major international meetings on these topics in November including COP27 in Egypt and the G20 Summit (where Chinese President Xi Jinping will meet with US President Joe Biden and other world leaders) in Indonesia.
