Environment & Climate Change

Decarbonizing existing buildings is a key component of greenhouse gas emission reduction strategies, but private investors have been slow to finance residential decarbonization projects because of a range of barriers. Authors Chang, Fornara, and Sanghvi argue that green banks could play a major role in unlocking public and private financing for projects that are currently financially unviable. 

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.

Joshua Schwartz and Sabrina Arias write that although Congress seems unable to act, enough states, cities and counties are mobilizing to make a dent in U.S. carbon emissions. The states, cities, counties, and towns that have committed themselves to upholding the Paris agreement currently release a majority of U.S. carbon emissions. If they do manage to meet their targets, they can make a meaningful difference.

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?

The Danish Minister of Climate, Energy, and Utilities expressed his hope that the tragic war in Ukraine will help accelerate the clean energy transformation by weaning Europe off Russian gas during a Virtual Forum (view recording here) last Friday (April 8). The event was hosted by the Harvard Project on Climate Agreements (HPCA) and moderated by Robert Stavins, HPCA Director and A.J. Meyer Professor of Energy and Economic Development. 

Russian military action in Ukraine could trigger an energy crisis even more serious than the one already hitting Europe. As has been pointed out, should the West hit Russia with severe new sanctions, President Vladimir Putin could cut off natural gas exports, leaving the continent shivering through midwinter. Yet there is another potential weapon of Russia’s that’s been less discussed and might be very effective: An ability to disrupt global oil markets, which would directly hit U.S. consumers.

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.
