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.

The International Energy Agency predicted last month that demand for global oil for transport will peak around 2026, plateau for all uses by 2028, and possibly hit a zenith by the end of the decade. Harvard experts say the forecasts track with what’s going on in the developed world, but the energy needs of less-wealthy nations pressing to develop their economies could foil expectations for years to come.

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.

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.

Joel Clement describes the influence of U.S. Senators Lisa Murkowski and Joe Manchin over the Department of the Interior and advises that a forward-looking legislator in a fossil-fuel state would be wise to fight aggressively for financial commitments to make the people in their state part of the vanguard of the new clean energy economy, rather than set back the U.S. economy by fighting the inevitable energy transition itself.

Joel Clement describes some immediate opportunities—and emphasize specific recommendations—to establish the Interior Department as a purposeful catalyst for a fair and just transition to clean energy, healthy ecosystems, and thriving communities.

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.

Corporations, organizations, and even governments are purchasing offsets to reduce their carbon footprint. This policy brief provides an overview of the offset process – who buys them, who produces them, and who certifies them; describes the emerging challenges facing this market; and makes recommendations for the future.

Arctic Innovator Samuel Gant writes that by adopting world-class environmental and safety standards and creating a sovereign wealth fund, Greenland can ensure mining serves its best interests.
