Al-Juaied and Whitmore examine the costs and prospects for direct air carbon capture and storage (DACCS), and identify types of funding needed for early deployment for DACCS and building momentum for later widespread deployment. The challenges of implementing DACCS at very large scale further emphasize the need for urgent and widespread action to reduce emissions, which should continue to be the main priority for meeting climate goals.

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.

 The Future of Coal Regions Study Group, co-sponsored by the Belfer Center's Environment and Natural Resources Program and the Wiener Center's Reimagining the Economy Project, will travel to coalfield regions in West Virginia on a trek led by Harvard Kennedy School’s Institute of Politics Resident Fellow 2022 and former West Virginia Secretary of State Natalie Tennant.

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.

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

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.

This paper analyzes clean hydrogen’s potential for driving emissions reductions in the mobility sector, focusing on road transportation, shipping, rail, and aviation. Overall, transportation is the second-largest producer of global CO2 emissions, after electricity and heat generation, and one of the hardest sectors to decarbonize due to its distributed nature and the advantages provided by fossil fuels in terms of high energy densities, ease of transportation and storage. 

Renewables are widely perceived as an opportunity to shatter the hegemony of fossil fuel-rich states and democratize the energy landscape. Virtually all countries have access to some renewable energy resources (especially solar and wind power) and could thus substitute foreign supply with local resources. Our research shows, however, that the role countries are likely to assume in decarbonized energy systems will be based not only on their resource endowment but also on their policy choices.
