Sustainability Defined

Sustainability Defined is the podcast that defines sustainability, one concept (and one bad joke) at a time. Hosted by Nethra Rajendran and Cecilia Rios. Each episode focuses on a single topic that pushes sustainability forward. We explain each topic with the help of an experienced pro, place it within our organizational tree, and help our listeners define what exactly sustainability is, episode by episode. We have divided our organizational tree into the following seven sectors: Energy Cities Natural Environment Transportation Business Policy Social Each episode is categorized under one of our sectors and visually depicted within our organizational tree. The more episodes we complete, the more the tree will visually define what exactly sustainability means. www.sustainabilitydefined.com Created by Scott Breen and Jay Siegel

In the hot seat this week - Nick Valenzia, Co-Founder of Leafr. We sat down with Nick to understand the "Green Skills Gap" and what that means in an economy where getting a job in sustainability feels so difficult. How is AI influencing the green jobs market? How is the lack of specialized sustainability professionals holding back global climate goals? What do professionals need to be aware of in order to succeed? What is this gap? 

Nethra and Cecilia also explore how Leafr is building the world’s largest network of independent sustainability specialists and curating the only rated database of sustainability tools and resources. Nick shares insights on what companies really need to make progress, how Leafr is changing the game for overburdened sustainability teams, and why accessibility and quality assurance are key to scaling impact.

This episode is brought to you by Leafr. As a thank you to our Definers, they are offering free consultations until November 30th, 2025. Book time here: https://calendly.com/nick-leafr/leafr-user-interview

Matcha, it’s everywhere, from your morning latte to the latest wellness trend. But what does it really take to bring this vibrant green powder from farm to cup, and what can its journey teach us about sustainability?

In this week’s episode, Nethra and Cecilia peel back the layers of matcha’s story tracing its production, supply chain, and booming global consumption. They explore how centuries-old traditions are colliding with modern demand, and why the way we grow and source matcha matters for people, planet, and the future of tea.

This episode also features a special interview with Michael Ham, Co-Founder and President of Wild Orchard Tea. Michael shares how Wild Orchard is reimagining the tea industry through regenerative farming building soil health, restoring ecosystems, and proving that sustainability and flavor can go hand in hand. His work offers a powerful glimpse into how a single crop, grown differently, can reshape the future of agriculture.
