Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Decarbonizing existing buildings is a key component of greenhouse gas emission reduction strategies, but private investors have been slow to finance residential decarbonization projects because of a range of barriers. Authors Chang, Fornara, and Sanghvi argue that green banks could play a major role in unlocking public and private financing for projects that are currently financially unviable. 

This discussion paper explores key areas of disagreement on Article 6 and explores possible outcomes from the upcoming Conference of the Parties to the United Nations Framework Convention on Climate Change (COP-26) in November 2021 in Glasgow.

Guangdong Province ranks first in economic output among China’s provinces and will play a major role in achieving China’s national climate-change goals. This paper examines the progress of Guangdong Province’s carbon dioxide emissions trading system (ETS) in reducing emissions; design features of the system; challenges it faces with regard to further development; and its relationship to China’s new national ETS.

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.

The United States government must require private industry and research institutions to take this threat seriously and develop cybersecurity policy and practices that will result in multiple layers of cybersecurity protections. This layered approach will require combined efforts from both the government and private industry to create an overlapping protection scheme.

On December 5, 1994, leaders of the United States, the United Kingdom, and the Russian Federation met in Budapest, Hungary, to pledge security assurances to Ukraine in connection with its accession to the Treaty on the Nonproliferation of Nuclear Weapons (NPT) as a non-nuclear-weapons state. The signature of the so-called Budapest Memorandum concluded arduous negotiations that resulted in Ukraine’s agreement to relinquish the world’s third-largest nuclear arsenal, which the country inherited from the collapsed Soviet Union, and transfer all nuclear warheads to Russia for dismantlement. The signatories of the memorandum pledged to respect Ukraine’s territorial integrity and inviolability of its borders, and to refrain from the use or threat of military force. Russia breached these commitments with its annexation of Crimea in 2014 and aggression in eastern Ukraine, bringing the meaning and value of security assurance pledged in the Memorandum under renewed scrutiny.

On the occasion of the 25th anniversary of the memorandum’s signature, the Project on Managing the Atom at the Belfer Center for Science & International Affairs at the Harvard Kennedy School, with the support of the Center for U.S.-Ukrainian Relations and the Harvard Ukrainian Research Institute, hosted a conference to revisit the history of the Budapest Memorandum, consider the repercussions of its violation for international security and the broader nonproliferation regime, and draw lessons for the future. The conference brought together academics, practitioners, and experts who have contributed to developing U.S. policy toward post-Soviet nuclear disarmament, participated in the negotiations of the Budapest Memorandum, and dealt with the repercussions of its breach in 2014. The conference highlighted five key lessons learned from the experience of Ukraine’s disarmament, highlighted at the conference.

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.

In this report, the authors conduct a benchmarking analysis for energy and CO2 emissions intensity of the steel industry among the largest steel-producing countries.

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.
