This is a pivotal moment in the fight against climate change. There is a need to act now and there are a lot of open questions on how to do that.

Net zero emissions by 2050 has emerged as the target that the world must hit in order to avoid the worst impacts of climate change. Policymakers and activists in the U.S. are working to put the net zero goal into law, and multiple major companies have already pledged to achieve carbon neutrality. But what will it really take to reach zero?

That’s what Political Climate will explore in the coming months in a new podcast series called “Path to Zero,” presented in partnership with Third Way. This series will look at how people are being affected by the transition to cleaner energy resources, and the economic challenges and opportunities created in the process. It will examine the technologies and policies we need to drive down carbon emissions, and the politics influencing this activity.

In this first episode of the series — introduced by Josh Freed, senior vice president of the climate and energy program at Third Way — we discuss why we’re talking about net zero emissions by 2050 to begin with. What is the climate science underpinning this goal? What does “net zero” mean? And what will the future look like if this goal isn’t met? We get the answers from scientist and climate strategist Dr. Jane Long, former associate director for energy and environment at the Lawrence Livermore National Laboratory.

“Path to Zero” episodes will air monthly on the Political Climate podcast feed, after the first two episodes air in January. Listen and subscribe on Apple Podcasts, Spotify, Stitcher, Google Play or wherever you get podcasts!
