Episodes typically run thirty-five to sixty minutes — most land between 50 min and 1h 6m — and the run-time is fairly consistent across the catalogue. None of the episodes are flagged explicit by the publisher. It is catalogued as a EN-language Education show.
The show is actively publishing — the most recent episode landed 6 days ago, with 9 episodes already out so far this year. The busiest year was 2025, with 15 episodes published. Published by Nethra Rajendran & Cecilia Rios.
From the publisher
Sustainability Defined is the podcast that defines sustainability, one concept (and bad joke) at a time. Hosts Scott Breen and Jay Siegel explore a new topic each episode with the help of an expert in the field. Each concept falls into one of seven sectors -- Energy, Cities, Natural Environment, Transportation, Business, Policy, and Social -- and is visually represented in a Sustainability Tree found at www.sustainabilitydefined.com.
