Environment & Climate Change

This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

Environmental policy experts discussed China’s energy policies during an event at the Harvard Kennedy School Belfer Center for Science and International Affairs on April 10, 2023. The event featured Weila Gong, a Belfer Center postdoctoral research fellow, and Georgetown University professor Joanna I. Lewis, who discussed their joint research exploring China’s coal consumption, its pledge to achieve carbon neutrality by 2060, and the political and economic factors hindering the country’s transition away from coal.

If the world is serious about addressing climate change, we should welcome forward momentum on this critical technology. Getting on track for net zero emissions by 2050 will require swiftly and massively ramping up carbon capture deployment.

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?

If you were wondering whether Europe is running out of options to deal with its continuing energy crisis, one of Britain’s largest energy suppliers just offered an answer.

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.

At one point in human history, water’s importance in war went beyond bearing convoys, hiding submarines, and slaking soldiers’ thirst. Water was often itself a weapon. In areas where it was scarce, armies took action to make it scarcer to force besieged enemy cities to capitulate, and in areas where it was abundant, combatants destroyed dams and watched the resulting floods carry their adversaries away. Today, however, most combatants recoil at the use of water as a weapon, and only the most depraved deploy it.

Since the end of World War II, nation-states in international conflict have made concerted efforts to restrain the weaponization of water. Distinct from realist and rationalist explanations, the historical record reveals the rise of an international normative inhibition—a “water taboo”—on using water as a weapon.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

By investing in the public and private sector research and development in this space, and by fostering a community of researchers, entrepreneurs, and investors literate in CO2 capture opportunities, the United States can be the leader of this new economic sector. It is essential for the Nation to build a vibrant and sustained research and development community spanning the public sector, academic and research domains, and for-profit companies, ensuring world leadership in this new technological domain.
