Financing Building Decarbonization: The Roles of Government and Private Sector Investors

    Authors:
  • Marco Fornara
  • Rushabh Sanghvi
| 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.

| June 2021

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.

Multi-objective Optimization of Energy and Greenhouse Gas Emissions in Water Pumping and Treatment

| 2020

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.

What Does Success Look Like for a Climate Czar?

| Dec. 02, 2020

President-elect Joe Biden’s decision to create a new cabinet-level position for climate-related issues — and to choose so prominent a figure as former Secretary of State John Kerry to fill it — demonstrates Biden’s sincerity over putting climate at the very center of U.S. foreign policy. It is easy to understate the importance of this appointment, given the flurry of czars created by most new administrations.

From his perspective as Principal Advisor to the Directorate General for Climate Action in the European Commission (EC), Jacob Werksman is cautiously optimistic about the direction of international climate policy. Werksman was the expert guest in the Conversations on Climate Change and Energy Policy webinar discussion last Thursday (July 9). The webinar series is sponsored by the Harvard Project on Climate Agreements (HPCA), and the interviews are hosted by HPCA Director Robert Stavins, the A.J. Meyer Professor of Energy & Economic Development at Harvard Kennedy School.

Geopolitical and Market Implications of Renewable Hydrogen: New Dependencies in a Low-Carbon Energy World

| March 2020

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.
