Climate change presents serious threats to the economy, the environment, and national security. To address these threats, a growing number of influential businesses, scientists, NGOs, policymakers, and thought leaders are calling for a carbon tax, which would put a price on carbon dioxide (CO2) and other greenhouse gas (GHG) emissions. Economists point to a price on GHGs as a key part of a strategy to address climate risks cost-effectively.

Last week, three new carbon tax proposals were released in Congress: Rep. Rooney’s bill and Rep. Lipinski’s bill in the House of Representatives, and the Coons/Feinstein bill in the Senate. Given the unprecedented level of movement in Congress surrounding carbon tax legislation, the Center on Global Energy Policy’s Carbon Tax Research Initiative launched a new online resource that explains what you need to know about a federal carbon tax in the United States, including comparisons of the existing federal carbon tax legislation introduced thus far.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
