Environment & Climate Change

HPCA and Director Robert Stavins played an active role at COP 28 in Dubai, which concluded on December 12 with an historic agreement calling for “transitioning away” from fossil fuels. Aside from moderating an official HPCA Side Event on reducing global methane emissions, Stavins also participated in several other panel discussions and forums on issues relating to the climate change negotiations as well as meetings with participants and journalists.

Amy Harder, the founding Executive Editor of the climate policy publication Cipher News, expressed her surprise with several positive outcomes from the recent 28th Conference of the Parties of the United Nations Framework Convention on Climate Change (COP 28) in Dubai during a special episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.”

The Harvard Project on Climate Agreements (HPCA) assembled a panel of leading academics and government officials to discuss strategies for achieving significant methane emissions reductions at relatively low costs at an official COP 28 Side Event last Wednesday (Dec. 6). The event, titled “Reducing Global Methane Emissions: Imperatives, Opportunities, and Challenges,” was moderated by HPCA Director Robert Stavins.

With 28th Conference of the Parties (COP 28) of the United Nations Framework Convention on Climate Change well underway, Jonathan Banks, the global director of the Methane Pollution Prevention Program at the Clean Air Task Force (CATF), is the guest in a special mid-COP episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” The podcast is produced by the Harvard Environmental Economics Program.

With the start of the 28th Conference of the Parties (COP 28) of the United Nations Framework Convention on Climate Change just days away, environmental economist Nat Keohane is expressing optimism that the new global stocktake will incentivize participating nations to step up their collective efforts to slow the rise of global temperatures. Keohane is the guest in a special pre-COP episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” The podcast is produced by the Harvard Environmental Economics Program.

Efforts around and impacts of global methane-emissions abatement will be the focus at an official side event on December 6 co-sponsored by the Harvard Project on Climate Agreements at the 28th Conference of the Parties (COP-28) of the United Nations Framework Convention on Climate Change (UNFCCC) in Dubai. Harvard Project Director Robert Stavins will also participate in a number of other events at COP-28.

Plastic pollution in the Arctic marine system is sparsely quantified, and few enforceable policies are in place to ameliorate the issue. In this paper, Dewey and Mackie estimate the flux of plastic through rivers, sea ice, and ocean, and quantify marine plastic pollution from Arctic shipping and fishing. They also examine how a suite of proposed policy interventions would quantitatively change those concentrations.

Direct air capture (DAC) is a type of technology that captures carbon dioxide directly from the air. As the negative impacts of climate change become ever more apparent, governments and private industries have funneled increasing support toward DAC as a critical pathway toward achieving a net-zero future. Although a promising technology, wide-scale deployment of DAC faces several significant challenges.

Legal scholar Andrey Todorov, Postdoctoral Research Fellow with the Arctic Initiative, reflects on the recent agreement reached by United Nations delegates to protect biodiversity in international waters and its implications for the Arctic. 

Divestment is a prominent strategy championed by activists to induce positive social change. For example, the current fossil fuel divestment movement includes over 1,500 institutions that control $40 trillion in assets. A primary pathway through which divestment is theorized to be effective is by influencing public beliefs and policy preferences, thus pressuring policymakers to take action. However, prior research only tests this argument via qualitative case studies. The authors assess the impact of exposure to information about fossil fuel divestment on public opinion through the use of national survey experiments in three major greenhouse gas emitters: the U.S., India, and South Africa.
