| Jan. 22, 2024

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.

Americans Agree with Their State and Local Officials on Climate Action

| July 26, 2022

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.

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.

Avoiding a Plastic Pandemic: The Future of Sustainability in a Post COVID-19 World

| January 2021

The ongoing COVID-19 pandemic is upending our lives and the global economy in ways unimaginable until recently. While the overall impacts are still difficult to quantify, ramifications are sure to be felt for decades to come. Providing secure, reliable, and affordable resources for all without causing devastating environmental consequences is perhaps the greatest challenge of the 21st century. But the pandemic has significantly altered dynamics and changed priorities. How is this impacting the quest for sustainability?

In this paper we analyze these challenges by focusing on the plastic industry. There is no doubt that plastic has molded society in many ways that make our lives easier and safer, but it has also created a global environmental and sustainability crisis. In order to curb our addiction to plastic, the world had been waging a war against virgin plastic, but the pandemic has turned an enemy into a much-needed ally. How can we leverage the advantages of plastic without contributing to the world’s environmental crisis? This dilemma poses a significant challenge, but also opens an opportunity to address sustainability at a systemic level through circularity and the transition to low-carbon alternatives to petroleum-based plastics.

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.
