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.

The price cap on Russian oil implemented today by the G7 countries plus Australia represents a novel approach to sanctions. The policy is designed to reduce Russian fossil fuel revenues while keeping Russian oil on the market. In this brief, Catherine Wolfram, Simon Johnson, and Łukasz Rachel explain the basic economic principles at work and discuss some of the critiques of the price cap. 

The price cap on Russian oil implemented today by the G7 countries plus Australia represents a novel approach to sanctions, according to a policy brief authored by Catherine Wolfram, Simon Johnson, and Łukasz Rachel and released today by Harvard Kennedy School’s Belfer Center for Science and International Affairs and the Mossavar-Rahmani Center for Business and Government. 

In this report, we propose a market reform pathway for Yunnan that is both feasible and applicable to address some of these challenges immediately, while aiming for a standard design based on well-documented international experience. Our proposal includes at its heart a pay-for-performance monthly capacity auction that can help cover revenue deficiencies in the energy market. Building on international experience with capacity markets, this approach provides incentives for availability when generation is needed most and is compatible with the adoption of a single energy market for all electricity resources. Out-of-market payments to cover stranded costs of certain firms can thus be minimized. Finally, engaging consumers in both these energy and capacity markets can create high-powered incentives to shift consumption to low-cost months and hours, benefitting the entire province.

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.

China announced it would launch a national carbon market in 2017, yet this policy is taking years to come into effect. What will it take for a carbon market to work in command-and-control China? This policy brief explores an understudied challenge—emissions accounting—and identifies potential opportunities that have arisen in the first phase of China’s national carbon market.

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.

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.

Environmental economists from Harvard, Yale, and other leading research institutions say an Environmental Protection Agency (EPA) proposal that would eventually allow more mercury pollution from power plants relies on a cost-benefit analysis that is fatally flawed. In a new report, the economists detail how the EPA’s calculations inappropriately fail to consider how reducing mercury pollution provides tens of billions of dollars in health benefits to the American people.
