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. 

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. 

Harvard Kennedy School’s Belfer Center for Science and International Affairs today announced the appointment of Lori Garver and Beth Sanner as non-resident Senior Fellows. Garver is a former Deputy Administrator of the National Aeronautics and Space Agency (NASA) and current CEO of Earthrise Alliance. Sanner was Deputy Director of National Intelligence for Mission Integration and is now Professor of Practice at the University of Maryland's Applied Research Lab for Intelligence Security. They will both share their experience and expertise with students and faculty of Harvard Kennedy School and the greater Harvard community.      

Guangdong Province ranks first in economic output among China’s provinces and will play a major role in achieving China’s national climate-change goals. This paper examines the progress of Guangdong Province’s carbon dioxide emissions trading system (ETS) in reducing emissions; design features of the system; challenges it faces with regard to further development; and its relationship to China’s new national ETS.

To mark Earth Day 2021, a number of Belfer Center climate, security, and intelligence experts took part in two conferences that identified and discussed the impacts of climate change not only on the environment and well-being of the world’s people, but also on international security and political stability throughout the world.

This report is derived from a half-day conference in April 2021 co-sponsored by the Intelligence Project and the Environment and Natural Resources Program at Harvard Kennedy School’s Belfer Center for Science and International Affairs, along with the Center for Climate and Security and The Cipher Brief. It explores the requirements of the U.S. Intelligence Community (IC) to fulfill the mission prescribed by President Biden, DNI Haines, and Secretary Kerry. The IC must rise to challenge, unshackled from the past, to re-imagine its role in combatting climate change. The IC has talked the talk about climate change, and now it needs to walk the walk. The stakes are too high not to do so.

On Friday, April 23, the Belfer Center’s Intelligence Project and Environment and Natural Resources Program, along with the Center for Climate and Security, co-hosted a half-day conference on Climate Change, Intelligence, and Global Security. The conference featured a keynote address from Secretary John Kerry, Special Presidential Envoy for Climate, and came directly after President Joe Biden’s Earth Day Leaders Climate Summit.

A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

Professor Joseph Aldy says the incoming U.S. administration can breathe new life into global efforts against climate change, but faces daunting political and economic obstacles.
