India aims to become a leading producer of green hydrogen by the next decade as part of its broader industrial and decarbonization strategies. This brief provides an overview of India's current hydrogen strategy, as well as the challenges - land and water scarcity, infrastructure gaps, and financing gaps - that must be addressed in order for India to achieve its ambitious goals.

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.

Mariana Budjeryn writes: War never stops at the border, especially on a continent like Europe. The European Union absorbed millions of Ukrainian war refugees and poured billions of euros into Ukraine's defenses and economic survival. The war permanently reshaped Europe: its demographics, political economy, and energy architecture are shifting in ways that will have irreversible long-term consequences. All of this is because in a very real sense Ukraine already is inextricably woven into the fabric of Europe: Ukraine’s pain is Europe’s pain and Ukraine’s gain will inevitably be Europe's gain, too.

David W. Kearn argues that deployment of nuclear weapons cannot rectify a perceived imbalance in conventional forces in the western Pacific.

Nuclear waste epitomizes the Anthropocene. Scientific discovery of nuclear fission in the 1930s ushered in the atomic age. The onset of nuclear weapons and nuclear energy production in the 1940s and 1950s then created a uniquely human problem with planetary implications. Today, 33 countries operate 442 nuclear power reactors, and nine countries possess nearly 13,000 nuclear arms. The result is high-level waste that is dangerously radioactive for millennia to come. Yet, there has never been a permanent waste solution in place. Technically feasible long-term nuclear waste storage options exist, but nearly all governments prefer riskier interim plans hidden from public view and debate. This chapter considers the likelihood of societies addressing the contentious environmental and economic politics of deep geological repositories; and it asks, how long will obfuscation of the risks of this unique Anthropocene challenge continue?

This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

Bruce Schneier, Kennedy School Adjunct Lecturer and an affiliate of the Belfer Center's Science, Technology, and Public Policy Program, appeared on GBH News to discuss the legal questions surrounding Montana's TikTok ban.

If the world is serious about addressing climate change, we should welcome forward momentum on this critical technology. Getting on track for net zero emissions by 2050 will require swiftly and massively ramping up carbon capture deployment.

Low-carbon energy technology (LCET) startups could play a key role in accelerating India’s decarbonization. Yet, understanding of the LCET startup landscape and what shapes it remains low. This paper provides an analysis of the Indian LCET startup landscape to fill this gap.

The Belfer Center Communications Team reached out to policy experts John P. Holdren and Matthew Bunn to reflect on the recent achievement of fusion ignition at the Lawrence Livermore National Laboratory.
