Climate Change Requires New Approaches to Disaster Planning and Response

    Author:
  • David J. Hayes
| June 2023

To date, most of the climate policy attention has been focused on the need to reduce the greenhouse gases that are causing climate change and, as a corollary, to accelerate the U.S. economy’s transition from fossil fuels to clean energy. Yet climate change also is straining our nation’s emergency response capabilities as traditional climate-infused disasters such as hurricanes and floods become more frequent and destructive. At the same time, the emergency response community faces new challenges as slower-to-develop climate impacts like drought, heat, and wildfire increasingly are hitting an acute tipping points and becoming life- and livelihood-threatening disasters.

Enabling a Significant Nuclear Role in China’s Decarbonization

| Dec. 02, 2021

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

The Future of Carbon Offset Markets

| Oct. 22, 2020

Corporations, organizations, and even governments are purchasing offsets to reduce their carbon footprint. This policy brief provides an overview of the offset process – who buys them, who produces them, and who certifies them; describes the emerging challenges facing this market; and makes recommendations for the future.

Is China's Hydrogen Economy Coming?

| July 28, 2020

This paper focuses on China and the potential role of renewable hydrogen in accelerating its transition to a low-carbon economy. Our research goal is to provide policymakers and other stakeholders the means to make informed decisions on technology innovation, policy instruments, and long-term investments in enabling infrastructure.

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.
