When it comes to energy transition solutions, wind and solar and big battery projects regularly make headlines, but we don’t often hear much about the hard-to-decarbonize sectors, like aviation, shipping, trucking, cement manufacturing, and steelmaking. Reducing emissions from these sectors is challenging for a number of reasons, but we must find ways to do it, because they account for about a third of global carbon emissions. And fortunately, there is a great deal of effort now being focused on these sectors, through an array of partnerships between governments, non-governmental organizations, and private industry. In this episode, we speak with the CEO of the Rocky Mountain Institute, a clean energy “think and do tank” founded by energy luminary Amory Lovins which has been working on energy transition for the better part of four decades, about some of the ways that we can decarbonize these sectors.
