Did firms accelerate decarbonization as a result of the 2015 Paris Agreement, particularly in industries where low-carbon options were technologically feasible? This paper challenges optimistic accounts of the Paris Agreement's influence and call for continued efforts to understand the limits of international agreements in driving firm behavior to address climate change.

The variety of topics studied in the field of International Relations contrasts sharply with the relatively anemic theoretical framework that IR scholars use to study those topics. This essay proposes three ordering principles as a framework for teaching and guide for intellectual inquiry: Anarchy, Nature, and Innovation.

The second Trump administration has disrupted global climate politics, turning the United States away from the clean energy and environmental policies of the Biden administration. Consequently, analytical attention is turning to a family of concepts referred to as “Climate Realism” (CR), which favors long-run investments in technology and adaptation over near-term climate mitigation efforts.

Kathryn Chelminski's recently published book examines how the clean energy regime complex – the fragmented, complex sphere of governance in the clean energy issue area characterized by proliferating and overlapping international institutions – can be effective in fostering energy transitions at the domestic level in emerging markets and developing economies.

As the U.S. grapples with the urgent need to speed clean energy deployment to meet net zero targets, interconnection delays are a major obstacle to achieving an energy transition. Why do some states manage to overcome political barriers to adapt interconnection regimes to be relatively more effective?

Green banks are an essential tool for the green energy transition. Though well-established in countries such as Germany, India, Australia, and the UK, green banks have gone mostly missing in action in the United States until recently. This white paper explains a vital new source of financing that has rapidly grown in the US over the last decade.

Community opposition to wind power can drive up costs for developers and stymie policymakers’ efforts to reduce greenhouse gases. In developing countries, how often do communities oppose wind power, why does the opposition happen, and to what extent will it become a barrier to clean energy expansion?

Climate Solutions Lab Postdoctoral Fellow Alexander S. Gard-Murray and co-author Watson Institute National Defense Fellow Lt Col Theodore J. Shanks created a map of U.S. military dependence on Russian fossil fuels.

Jan Stockbruegger recently wrote, "22 Countries Agreed To Establish Green Shipping Routes. That’s Big News," which explains why a new initiative may not only help build clean maritime industries, but also build support for more ambitious climate policies in shipping.

Jeff Colgan and co-author Alexander Gard-Murray recently published a Climate Solutions White Paper focusing on how the summary findings directed at policymakers and technical audiences might be improved, and how a new publicfacing "Summary for American Families" could help the NCA communicate its results more broadly.

Jonas Nahm, Assistant Professor of Energy, Resources, and Environment at the Johns Hopkins School of Advanced International Studies, recently wrote this white paper for the Climate Solutions Lab on clean tech manufacturing.
