In this episode of the Climate Confident Podcast, I sit down with Dr. Gary Yohe, one of the world’s leading climate economists and a long-time IPCC author who shared in the 2007 Nobel Peace Prize.
Gary has spent more than 40 years reframing how we think about climate change, not as a distant environmental issue, but as a risk management challenge with urgent economic, social, and financial consequences.
We explore his simple but powerful framework: abate, adapt, or suffer. These are the only three climate choices we have left, and some level of suffering is now inevitable. From the collapse of insurance markets in California to the risks of sea-level rise in San Francisco, Gary shows how climate change is already disrupting finance, housing, and community resilience.
But this isn’t all doom. Gary draws inspiration from Václav Havel’s words that hope is not optimism but the conviction that action makes sense, regardless of the outcome. It’s a message of courage for policymakers, businesses, and citizens alike.
👉 If you want to understand why climate economics, risk, and resilience are at the heart of the crisis, and what we can do to respond—this conversation is essential.

![How Rotor Sails Are Cutting Shipping Emissions by 50% | Norsepower CEO Heikki Pöntynen
Can shipping cut fuel use by 50%—today?
Norsepower’s modern rotor sails are already slashing fuel burn and CO₂ emissions on real-world voyages. In this episode of Climate Confident, CEO Heikki Pöntynen reveals how this century-old idea, re-engineered with modern tech, is transforming maritime decarbonisation—with up to 50% savings on some routes.
Watch to discover the Magnus effect in action, why IMO regulations have supercharged adoption, and how wind power is working alongside biofuels and electric ships to help hit net zero by 2050.
Can the shipping industry slash fuel use by up to 50% without waiting decades for new fuels?
In this episode of Climate Confident, I speak with Heikki Pöntynen, CEO of Finnish cleantech leader Norsepower, about how modern rotor sails are transforming maritime decarbonisation.
We unpack how Norsepower has revived the Flettner rotor – a century-old wind propulsion technology – and turned it into a scalable solution already cutting CO₂ emissions by 5–25% on most routes, with some transatlantic crossings aiming for 50% savings.
Heikki explains:
The Magnus effect that powers rotor sails
How AI-driven automation maximises efficiency
Why stricter IMO regulations have cut payback times to as little as one year
The booming market for retrofit solutions and “rotor sail ready” ships
How wind propulsion complements biofuels and electric vessels
With 26,000 tonnes of CO₂ saved to date, this isn’t a concept – it’s a proven, operational technology reshaping the future of sustainable shipping.
If you care about net zero shipping by 2050, maritime innovation, or practical climate solutions that work today, this conversation is essential listening.
