Prospects for Direct Air Carbon Capture and Storage: Costs, Scale, and Funding

| Nov. 30, 2023

Al-Juaied and Whitmore examine the costs and prospects for direct air carbon capture and storage (DACCS), and identify types of funding needed for early deployment for DACCS and building momentum for later widespread deployment. The challenges of implementing DACCS at very large scale further emphasize the need for urgent and widespread action to reduce emissions, which should continue to be the main priority for meeting climate goals.

COP26 Takeaways: Statement from Laura Diaz Anadon

| Nov. 18, 2021

What was accomplished? COP26 created pressure for some countries to produce revised  Nationally Determined Contributions, helped catalyze new pledges to reduce emissions (including from India), led to the approval of the rules to govern international cooperation and carbon markets (the Paris Rulebook) addressing the issue of double counting, and served as the Launchpad for some novel initiatives that could play a useful role. Among the announcements that were made, was one that recognizes the importance of strategic investment and government action to lower the cost of technologies to reach carbon neutrality.

There is an urgent need to incorporate the latest science on carbon emissions from permafrost thaw and northern wildfires into international consideration of how much more aggressively societal emissions must be reduced to address the global climate crisis.

The Geopolitics of Renewable Hydrogen

| May 2021

Renewables are widely perceived as an opportunity to shatter the hegemony of fossil fuel-rich states and democratize the energy landscape. Virtually all countries have access to some renewable energy resources (especially solar and wind power) and could thus substitute foreign supply with local resources. Our research shows, however, that the role countries are likely to assume in decarbonized energy systems will be based not only on their resource endowment but also on their policy choices.

Settled Enough: Climate Science, Skepticism and Prudence

| May 24, 2021

John P. Holdren writes that because of the huge potential importance of the evidence of global climate change for policy and for human well-being on the largest scale, moreover, its details and its conclusions have been scrutinized and re-scrutinized to a staggering degree. It was the conclusions based on this evidence, made even more robust by the continuing growth of climate-related damages in the ensuing years, that motivated 195 countries  to sign the Paris Agreement in December 2015. The science was rightly considered "settled enough."
