Climate Confident

Climate Confident is the podcast for business leaders, policy-makers, and climate tech professionals who want real, practical strategies for slashing emissions, fast.

Every Wednesday at 7am CET, I sit down with the people doing the work, executives, engineers, scientists, innovators, to unpack how they’re driving measurable climate action across industries, from energy and transport to supply chains, agriculture, and beyond.

This isn’t about vague pledges or greenwashing. It’s about what’s working, and what isn’t, so you can make smarter decisions, faster.

We cover:

Scalable solutions in energy, mobility, food, and finance
The politics and policies shaping the energy transition
Tools and tech transforming climate accountability and risk
Hard truths, bold ideas, and real-world success stories

👉 Climate Confident+ subscribers get full access to the complete archive, 230+ episodes of deep, data-driven insights.
