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

Did you know that airplanes can run on waste cooking oil, municipal solid waste, forestry waste, and even algae in the form of Sustainable Aviation Fuels (SAFs)? Well, they can. 

Biomimicry, Sustainable Aviation Fuels (SAFs), and aircrafts inspired by GEESE? Learn about some of the innovations happening right now in the aviation industry and where it's headed in the coming decades. The industry has some ambitious goals of reaching net zero by 2050, running aircrafts on mainly SAFs, using newer lightweight materials to reduce fuel consumption, and even getting aircrafts to fly in the same v-pattern as flocks of geese to lower their carbon footprints.

Hosts, Cecilia & Nethra, took field trip to Toulouse, France and attended the Airbus Summit 2025. Learn about their insights from the summit and hear some lightning interviews from a few of the leading experts at Airbus such as:

  • Julie Kitcher, Chief Sustainability Officer
  • Jonathan Beck, Flight Operations R&T IPT Leader
  • Sue Partridge, Head of Wing of Tomorrow Programme
  • Antjie Bulmann, Direct Air Capture Expert
