David Keith

Expert in Energy and Environmental Technology

David Keith studies our climate and the many ideas we’ve come up with to fix it. A wildly original thinker, he challenges us to look at climate solutions that may seem daring, sometimes even shocking. Currently a professor at Harvard University, David was listed as one of Time magazine’s “Heroes of the Environment” in 2009, and advises on a number of high-profile advisory panels around the world.

David has worked near the interface between climate science, energy technology and public policy for twenty years. He took first prize in Canada’s national physics prize exam and won MIT’s prize for excellence in experimental physics. David’s academic appointments are at Harvard where he serves as the Gordon McKay professor of applied physics in the School of Engineering and Applied Sciences, and as a professor of public policy at the Harvard Kennedy School. David also serves as president of Carbon Engineering, a start-up company developing industrial scale technologies for capture of CO2 from ambient air.

David has addressed technical audiences with articles in Science and Nature; has consulted for national governments, global industry leaders, and international environmental groups; and has reached the public through media outlets such as the BBC, NPR, CNN, and the editorial page of The New York Times.

A Case for Climate Engineering

David Keith argues that after decades during which very little progress has been made in reducing carbon emissions we must put this technology on the table and consider it responsibly. That doesn’t mean we will deploy it, and it doesn’t mean that we can abandon efforts to reduce greenhouse gas emissions. But we must understand fully what research needs to be done and how the technology might be designed and used. David provides a clear and accessible overview of what the costs and risks might be, and how climate engineering might fit into a larger program for managing climate change.
