In this episode of CleanTalk, we sit down with Thaddeus Anim-Somuah, a corporate sustainability professional, chemical engineer, World Energy Council contributor, and advisor on impact and energy-transition investments, to explore how energy, materials, finance, and human behaviour are deeply interconnected, and why sustainability only works when it creates real value for people.

Drawing on his upbringing in Ghana, his engineering background, and his work across industry, finance, and policy, Thaddeus unpacks the circular economy, material efficiency, behavioural change, sustainable finance, and the limits of “moralised” renewable energy narratives. We discuss why optimisation often matters more than abundance, how regulation like CSRD is reshaping corporate behaviour, and why finance, more than technology alone — will determine the pace of the energy transition.

This episode is for sustainability professionals, engineers, investors, policymakers, founders, and anyone trying to understand how the energy transition actually works beyond slogans, marketing, and moral posturing.

Enjoy!
