For the New York Times Opinion podcast Sway, I produced this conversation between Kara Swisher and Bill Gates. Gates’s latest book is How to Avoid a Climate Disaster, and in it he details the engineering breakthroughs that will be necessary if we’re ever going to achieve net zero greenhouse gas emissions. For all the attention paid to electric vehicles, the more pressing question might be: how are you going to make cement? You can listen to the episode on the Times website here, or on your podcast app of choice.
