Great way to relax after a day of selling solar.

Best Podcast Yet

I listen to a lot of podcasts. I love using them to feel like I’m being productive when I don’t actually feel like being productive. As a result, all the podcasts I listen to are about sustainability/urban planning. Sustainability Defined is my absolute favorite and my go to recommendation for anyone interested in sustainability podcasts. Jay and Scott, keep up the good work!

Just finished binging EVERY episode

I’m a college student wanting to go into the sustainability industry however I’m unsure of what sector. I downloaded every environmental podcast I could find, and this one is by far the best. The hosts are so relatable. They pick great topics and break down complex ideas with entertaining analogies. I now have a better idea of how to help make the world more sustainable on a professional and personal level. Thanks Jay and Scott, keep it up!
