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. 

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.

In May 2023, the Arctic Initiative hosted a workshop in partnership with the Science and Technology Directorate of the U.S. Department of Homeland Security (DHS). The focus was on the challenges posed by the impacts of rapid climate change in Alaska; how DHS and its components— including the Federal Emergency Management Agency (FEMA), the Cyber and Infrastructure Security Agency (CISA), and the U.S. Coast Guard (USCG)—are addressing them; and what possibilities may exist for DHS to do more and better.

Alaska is an important region for the Department of Homeland Security (DHS), given the
Department’s statutory authority and responsibilities. This reality applies with particular force to the U.S. Coast Guard (USCG), with its jurisdiction over fisheries enforcement, drug interdiction, marine safety, oil spill response, search and rescue, and more. This policy brief provides an overview of the challenges facing the USCG in its domains of operation around Alaska—the Arctic Ocean, the North Pacific Ocean, the Bering Sea, the
Chukchi Sea, and the adjacent communities.

This report summarizes a workshop co-hosted by the Arctic Initiative and the Science and Technology Directorate of the U.S. Department of Homeland Security (DHS), focused on the challenges posed by the impacts of rapid climate change in Alaska.

As climate change and economic activity in the region accelerate in the Bering Strait region, the United States and Russia have a common interest in mitigating these shared environmental risks. A November workshop hosted by Harvard Kennedy School’s Arctic Initiative, the Wilson Center’s Polar Institute, and the World Wildlife Fund (WWF) brought together seventeen experts to explore potential actions that the United States and Russia could pursue, jointly or independently, to protect the Bering Strait’s sensitive marine ecosystem and coastal communities. 

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.

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. 

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.

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.
