DeepSummary
The episode is a re-aired interview with Cameron Hepburn, a Professor of Environmental Economics at the University of Oxford. They discuss the economics of the clean energy transition, the impacts of geopolitical events like Russia's invasion of Ukraine, and policy levers to accelerate the transition to net-zero emissions. Cameron highlights the importance of pricing carbon emissions correctly and embracing competition to drive innovation and cost reductions in clean energy technologies.
Hepburn acknowledges the challenges of the transition, such as potential mineral supply bottlenecks and the need for grid infrastructure upgrades. However, he argues that the long-term cost curve for clean energy is deflationary, making it economically advantageous over fossil fuels. He also emphasizes the role of academic research in monitoring progress, verifying commitments, and educating the public on effective climate policies.
The conversation touches on topics like the impact of the Inflation Reduction Act, carbon border adjustments, and the balance between cooperation and competition in driving the energy transition. Hepburn advocates for policies that align with self-interest and competition while encouraging international collaboration to address the global challenge of climate change.
Key Episodes Takeaways
- The clean energy transition is being accelerated by cost reductions in technologies like wind, solar, and electrolysis, making it economically advantageous compared to fossil fuels in the long run.
- Appropriate carbon pricing and market-based policies are crucial for incentivizing decarbonization across various sectors and aligning economic incentives with environmental goals.
- Geopolitical events like Russia's invasion of Ukraine and policy measures like the Inflation Reduction Act can both accelerate and hinder the clean energy transition in different regions and sectors.
- Academic research plays a vital role in monitoring progress, verifying commitments, educating the public on effective climate policies, and advancing solutions like carbon removal technologies.
- While international cooperation is essential, competition between countries and companies can also drive innovation and cost reductions in clean energy technologies.
- Challenges remain, such as potential mineral supply bottlenecks, grid infrastructure upgrades, and public acceptability of climate policies, requiring continued research and policy interventions.
- Carbon border adjustments and other trade-related measures could incentivize the adoption of carbon pricing and climate policies globally while addressing concerns of competitive disadvantages.
- A balanced approach that harnesses both market forces and government interventions is necessary to navigate the complexities of the clean energy transition effectively.

- “If we did have a lovely global carbon price that was shared across countries and so on, then you wouldn't have to worry so much about this because every part of the value chain would be incentivized to sort itself out. But we don't. And as you say, even if we did, some companies would want to go faster than others.“ by Speaker A
- “The reality is that there are some really amazing, wonderful, useful additional projects out there where offsets are doing a ton of good, and there is a chunk of greenwashing out there as well.“ by Speaker A
- “I think academic work remains very important. So I wouldn't disagree with you that we know that we've got a big problem on a scientific level. It's not to say we know all of the impacts, not to say we know where all the tipping points are, etcetera. There's still work to be done there, but we know we've got a big problem.“ by Speaker A

Getting the global energy system to net-zero – a state in which it emits no more greenhouse gasses than it absorbs – means deploying clean energy infrastructure at a pace without historical precedent. The ripple effects of this transition are already apparent in business, geopolitics, and in people’s daily lives.
Increasing public concern over climate change and breakthroughs in clean energy technology have rendered this challenge more achievable. But turning this momentum into tangible progress will require careful policymaking and implementation, across all levels of government.
How might the clean energy transition reconfigure the global economy? What levers can policymakers pull to accelerate it? And what emerging solutions are already changing the outlook for net zero?
Today we’re re-running host Jason Bordoff’s interview with Cameron Hepburn about the economics of the climate crisis.
Cameron is a Professor of Environmental Economics at the University of Oxford and Director of the Smith School of Enterprise and the Environment. He also serves as the Director of the Economics of Sustainability Programme, based at the Institute for New Economic Thinking at the Oxford Martin School. Cameron has over 30 peer-reviewed publications spanning economics, public policy, law, engineering, philosophy, and biology.
In a summer of both heightened climate ambition and heightened alarm over climate change, this conversation was held in the aftermath of the COP27 climate summit. Jason and Cameron discussed how technology developments are accelerating the energy transition and how to scale their impact.
