Environment & Climate Change

Today’s economic crisis leaves us with an unsettling and perplexing regret. Why weren’t financial portfolios already adjusted for risks that stem from health events such as pandemics? After all, financial portfolios are adjusted for liquidity risks, market risks, credit risks, and even operational and political risks.

Columbia University Professor Scott Barrett assessed the massive global efforts underway to address COVID-19 and the potential impacts of the pandemic on our lives in the future in a special episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program. Listen to the interview here.

In this paper, a quantitative Waste to Energy Recovery Assessment (WERA) framework is used to stochastically analyze the feasibility of waste-to-energy systems in selected cities in Asia.

Joseph Nye writes that while trade wars have set back economic globalization,  the environmental globalization represented by pandemics and climate change is unstoppable. Borders are becoming more porous to everything from drugs to infectious diseases to cyber terrorism, and the United States must use its soft power of attraction to develop networks and institutions that address these new threats.

In this edition of Columbia Energy Exchange, host Jason Bordoff and Professor Joseph Aldy explore the role of climate-change and broader environmental policy in the U.S. federal government’s emergency economic stimulus funding package.

This paper examines a recent, rapid, and ongoing transition of India's lighting market to light emitting diode (LED) technology, from a negligible market share to LEDs becoming the dominant lighting products within five years, despite the country's otherwise limited visibility in the global solid-state lighting industry.

Robert Stavins, director of the Harvard Environmental Economics Program, speaks with Joseph Aldy, professor of the practice of public policy at Harvard Kennedy School. The discussion covers Aldy's experience in government service, and the prospects for meaningful and effective climate change policy in the United States.

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.

Growing concern around climate change has ignited recent interest in carbon capture, utilization, and storage (CCUS) technologies and generated a series of studies on its global market potential.
