In this episode of the Sustainable Ambassador Podcast, I sit down with Ralph Thurm, founder of a|head Ahead and co-founder of r3.0, to explore a pressing question:

Has the sustainability movement lost its way?

Drawing on decades of experience—from Siemens and Deloitte to his leadership role at GRI—Ralph delivers an unflinching critique of the current state of sustainability.

Through our conversation, he questions whether sustainability, as it's practiced today, even exists, and together we unpack what went wrong—from flawed assumptions and missed opportunities to the industry's failure to deliver systemic transformation—and what needs to happen now to reclaim the original purpose of the movement.

She discusses the growing complexity of data, the emergence of uninsurable risks, the role of regulation, and the pendulum swing between generalists and specialists.

The conversation offers a candid look at the current environment, the risks of dilution and defensiveness, and thoughtful advice for those working—or entering—the sustainability field today.
