Path to Zero is a podcast focused on clean energy and the journey toward a low-carbon future. Zero emissions is a goal we can all get behind, but how do we meet the growing energy demands of the world AND reduce carbon in the atmosphere?

That’s the question Path to Zero guests and its host, Tucker Perkins, CEO of the Propane Education & Research Council, will be exploring. Topics include the clean energy continuum, “new urbanist” perspectives on clean energy, the challenge of a 2 centigrade change in the earth’s temperature poses, the science of warnings, and cities of tomorrow, just to name a few.
