Addressing climate change with meaningful policy action will be neither cheap nor easy, but presently the greatest barrier to action in the United States is not technological, nor perhaps even economic, but fundamentally political.  This becomes a theme in my latest podcast, where I engage in a wide-ranging conversation about economics, politics, and climate change with Gernot Wagner, Clinical Associate Professor at New York University, and former staff economist at the Environmental Defense Fund.

You can hear our complete conversation in the podcast here.

In these podcasts – “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program – I converse with very well-informed people from academia, government, industry, and NGOs.  Gernot Wagner fits well in this group, with experience in academia, industry, and the NGO world.

Wagner, whose career also includes time spent as a consultant at the Boston Consulting Group and a journalist at the Financial Times, brings to his thinking about the economics of climate change policy a rich and varied set of perspectives gained through his years of multi-sectoral experience.  

He is a graduate of Harvard College, where he took my environmental economics course as a freshman (and then proceeded to receive the highest grade in the class).  In addition, I had the privilege of serving as chair of Gernot’s dissertation committee when he received his Ph.D. in Political Economy and Government from Harvard in 2007.

Gernot Wagner is author of two books, “But will the Planet Notice: How Smart Economics Can Save the World?,”and “Climate Shock: The Economic Consequences of a Hotter Planet,” which he co-wrote with the late Harvard Professor Martin Weitzman, whom he had met his first week on the Harvard campus as a freshman in 1998.

“I went to meet Marty on a Thursday that week,” Wagner recalls in our podcast conversation. “I remember Marty sitting me down and first of all, taking me seriously…much like you did. You did try to dissuade me from taking your class, but then I ended up taking it later that year. But Marty sat me down and guided me through, maybe in an attempt at dissuading me frankly of wanting to become an environmental economist or academic.”

In my podcast conversation with Gernot, we turn to the topic of current-day climate policy, and Wagner sounds cautiously optimistic about the chances that the United States will meet the Biden Administration’s recently announced commitment to reduce CO₂ emissions by 50-to-52 percent below 2005 levels by the year 2030, saying that it would be technically and economically feasible, although politically difficult.

“I’d like to think I can make a cogent argument for why it will happen, and this administration is uniquely positioned to make it happen. And the approach it is taking seems to be on the right path,” Wagner says, while also admitting that it will be a challenge for the administration to get any meaningful climate policy through a divided Congress.

Wagner also expresses his hope for establishing a carbon price of between 60 and 300 dollars per ton to provide incentives for companies and industries to reduce CO₂ emissions. Exxon, he notes, has recently come out in support of a carbon price of 50 dollars per ton, but Democrats in Washington are not satisfied with that proposal.

“The progressives in the House wants something that has a higher price equivalent. The Biden Administration might be slightly less ambitious on that front,” he says. “All of it is still much more ambitious than the…simple 50 dollar per ton of CO₂ carbon tax.”

At the end of our conversation, I ask Wagner for his thoughts on the youth climate movements that became prominent in 2019.

“What we do see is amazing action in the right direction, on a whole lot of different dimensions,” Gernot remarks. “Now we are back to – what should this movement push for? And frankly, now we are back to the raw politics of it all. It’s very, very difficult to see – the one simple approach that will just solve it all. That basically doesn’t exist. It exists in theory, maybe. Not in practice.”
