How can China make good on its pledge to reach carbon neutrality by 2060? In Foundations for a Low-Carbon Energy System in China, a team of experts from China and the United States explains how China's near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for a smoother and less costly national energy transformation.

What types of foreign policy cues are most likely to turn public opinion against a popular emerging norm? Since 2017, the U.S. government has sought to discredit the Treaty on the Prohibition of Nuclear Weapons and its nuclear nonpossession norm among the largely prodisarmament American public. The authors fielded a national U.S. survey experiment (N=1,219) to evaluate the effects of these elite cues as well as social group cues on public opinion. Their study thus offers one of the first experimental assessments of public attitudes toward nuclear disarmament.
