Conversations on Sustainability


Jay Siegel is an Acquisitions and Development professional out of Denver. A&D by day. Podcaster, urban planner, and environmentalist 24/7.

Jay and podcasting partner Scott Breen started Sustainability Defined in 2016 with an episode about electric bikes. Now they’ve got an “acclaimed podcast that’s downloaded in over 100 countries, included on course curricula at universities across the US, and regularly listed as one of GreenBiz’s top sustainability podcasts.” They collect a lot of heavy hitters as guests: from Google to Allbirds, to thinkers from the Sierra Club, the US Green Building Council, Penn State, and tons more. Sounds good to us.

Jay says: “On the podcast we break down all kinds of nebulous concepts, so it’s a thrill to work where our community impacts are so tangible. I feel fortunate to be able to exercise all sides of my brain to promote sustainability wherever possible.

Thanks, Jay. Keep spreading the good word on sustainability in all its forms. You can listen to Sustainability Defined at sustainabilitydefined.com or wherever you get your podcasts.
