Harvard Kennedy School hosted Leon Clarke, Director of Decarbonization Pathways at Bezos Earth Fund, for an Energy Policy Seminar to discuss the economic challenges that are slowing the pace of the energy transition.

The International Energy Agency predicted last month that demand for global oil for transport will peak around 2026, plateau for all uses by 2028, and possibly hit a zenith by the end of the decade. Harvard experts say the forecasts track with what’s going on in the developed world, but the energy needs of less-wealthy nations pressing to develop their economies could foil expectations for years to come.

Joel Clement describes the influence of U.S. Senators Lisa Murkowski and Joe Manchin over the Department of the Interior and advises that a forward-looking legislator in a fossil-fuel state would be wise to fight aggressively for financial commitments to make the people in their state part of the vanguard of the new clean energy economy, rather than set back the U.S. economy by fighting the inevitable energy transition itself.

Joel Clement describes some immediate opportunities—and emphasize specific recommendations—to establish the Interior Department as a purposeful catalyst for a fair and just transition to clean energy, healthy ecosystems, and thriving communities.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

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.

Climate@HKSis a new online resource for navigating the full range of climate-related activity across Harvard Kennedy School's research centers, degree programs, and administrative departments.

Arctic Innovator Samuel Gant writes that by adopting world-class environmental and safety standards and creating a sovereign wealth fund, Greenland can ensure mining serves its best interests.

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.

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.
