From cars and ships to bridges and skyscrapers, steel forms the landscape of modern life. At the same time, steelmaking is one of the world’s biggest industrial sources of climate-warming carbon dioxide. Antoine Allanore, a professor of metallurgy at MIT, explains how CO2 became so entrenched in the chemistry of steelmaking—and the creative ways scientists and engineers are trying to get it out.

We gratefully acknowledge Katie Daehn, postdoctoral associate, and Matthew Michalek, Ph.D. student and research assistant, of the Allanore Group for additional assistance and participation in this episode.

Solutions to climate change, like building clean energy, come with a price tag. But unchecked warming also brings serious costs. As we make investments to rein in our climate pollution, how should we weigh costs and benefits? Dr. Jennifer Morris of MIT joins the show to explain how economists have tried to pin down the dollar costs of a warming planet, and why a clear answer has proved elusive. Together, we’ll ask how the tools of economics can help us plan for a better, more prosperous future, even in the face of uncertainty.

What exactly is a carbon price, and how does it work? To prepare for a new episode about climate economics, we’re re-airing this season one episode in which MIT professor Christopher Knittel explains economists’ favorite tool for addressing climate change. Professor Knittel also returns for a special update on big developments in the world of carbon pricing, from Canada, China, and the European Union.
