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.

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.

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.

This study group will explore the role of the private sector in evolving energy systems, and how corporations might change in a climate constrained world. 

Civil society has played a very important role in nuclear security over the years, and its role could be strengthened in the future. Some nuclear organizations react against the very idea of civil society involvement, thinking of only one societal role—protesting. In fact, however, civil society has played quite a number of critical roles in nuclear security over the years, including highlighting the dangers of nuclear terrorism; providing research and ideas; nudging governments to act; tracking progress and holding governments and operators accountable; educating the public and other stakeholders; promoting dialogue and partnerships; helping with nuclear security implementation; funding initial steps; and more. Funding organizations (both government and non-government) should consider ways to support civil society work and expertise focused on nuclear security in additional countries. Rather than simply protesting and opposing, civil society organizations can help build more effective nuclear security practices around the world.

Realistic, creative vulnerability assessment and testing are critical to finding and fixing nuclear security weaknesses and avoiding over-confidence. Both vulnerability assessment and realistic testing are needed to ensure that nuclear security systems are providing the level of protection required. Systems must be challenged by experts thinking like adversaries, trying to find ways to overcome them. Effective vulnerability assessment and realistic testing are more difficult in the case of insider threats, and special attention is needed. Organizations need to find ways to give people the mission and the incentives to find nuclear security weaknesses and suggest ways they might be fixed. With the right approaches and incentives in place, effective vulnerability assessment and testing can be a key part of achieving and sustaining high levels of nuclear security.
