Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Among the many issues surrounding China’s ongoing military modernization, perhaps none has been more dramatic than its nuclear weapons program. For decades, the Chinese government was content to maintain a comparatively small nuclear force. As recently as 2020, China’s arsenal was little changed from previous decades and amounted to some 220 weapons, around five to six percent of either the U.S. or Russian stockpiles of deployed and reserve warheads.

“This is not a decision or set of steps that are happening in haste by any means, and this is a practice that is common and consistent around the world and with the nuclear energy industry,” said Marina Lorenzini of the Belfer Center for Science and International Affairs at the Harvard Kennedy School of Government.

According to data posted online by the Japanese Ministry of Economy, Trade and Industry, water with much higher levels of tritium has been discharged by nuclear facilities in countries including China, South Korea, Canada and France in line with local regulations.

Lorenzini said that the IAEA’s active engagement in the Fukushima process “makes me feel a lot more comfortable and confident with the events we see playing out today.”

The IAEA said this week that it would maintain an onsite presence at the Fukushima plant, where it opened an office last month, and publish real-time and near real-time monitoring data.

“I think we have good reason to believe that this will be a well-monitored and well-maintained operation,” Lorenzini said.

The Harvard Initiative to Reduce Global Methane Emissions released its first publication in May 2023: a research brief titled “Updating Estimates of Methane Emissions: The Case of China.” The Initiative is one of five interdisciplinary research clusters funded by the Salata Institute for Climate and Sustainability at Harvard University. The Harvard Project on Climate Agreements collaborates in the implementation of the Initiative.

Following the COP27 climate conference in Egypt, Robert Stavins said in an interview with the Harvard Gazette that the talks were both frustrating and hopeful: frustrating because they did little to accelerate the slow pace of action to reduce carbon emissions, and hopeful because of a reawakened dialogue between the world’s biggest emitters—the U.S. and China—and movement to address climate-related damage to the world’s most vulnerable nations.

China and the United States are back on a productive track to adopt more cooperative approaches on global climate change. Those were the sentiments expressed by Harvard Project Director Robert Stavins on Wednesday (November 16) during a side event focusing on the China National Climate Change Assessment Report at COP27 in Sharm El Sheikh, Egypt.

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?

Juliette Kayyem writes that deliberately accepting some risks, and then being prepared when disaster strikes, will serve human societies better than pretending that perfect safety is achievable. We cannot prevent an earthquake or a tsunami, but we have control over how much death and destruction it causes.

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

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.
