How to Assess the Outcome of COP28
Given that this year’s United Nations Climate Change Conference was hosted by a petrostate and led by a fossil-fuel CEO, climate campaigners understandably had low expectations. Yet the summit did deliver some new commitments, and there is good reason to think that they are more than just empty words.
What Steel Decarbonization Needs
It is both technically possible and economically feasible to eliminate almost all the carbon dioxide from iron and steel production by mid-century, thus cleaning up an industry that accounts for 10% of global emissions. But progress will not happen without a concerted policy push.

Taming Carbon
When the Price Is Right
The Green Growth Mindset
Heated academic debates between proponents and opponents of traditional economic growth under capitalism might make for good television, but they offer little in the way of solutions. Climate change demands that we achieve both growth and degrowth, depending on the activity and economic sector in question.
Carbon Capture and Delay
As long as coal plants are still operating, it is a good idea to require them capture their carbon dioxide emissions. But those designing policies to hasten such practices must tread carefully, lest they unwittingly extend the life of dirtier energy sources.
What the Climate Fight Is Really About
Hint: It's about minimizing risks and uncertainties.

How to Think About Climate-Tech Solutions
To think that technology will save us from climate change is to invite riskier behavior, or moral hazard. Whether a climate technology creates new problems has little to do with the solution, and everything to do with us.
Will the Banking Busts Hurt Clean Tech?
Rather than impeding the clean-energy race, the recent collapse of the US start-up community's go-to bank offers valuable lessons for managing the public-private minuet that the net-zero transition requires. The doomsayers are missing the bigger picture.
Europe Must Tax Brown and Subsidize Green
The US Inflation Reduction Act is a landmark legislative package that should be welcomed around the world, despite its putatively protectionist features. Owing to the positive learning-by-doing spillovers that follow from green subsidies, Europe and the rest of the world ultimately will benefit, too.

Realism About Techno-Optimism
Speeding up the adoption of already proven and scalable technologies, and exposing the many hidden costs associated with fossil fuels, is a necessary goal. Achieving it will require new policies to guide investments in the right direction, and techno-optimists ought to be the loudest advocates.
Davos produktiv für das Klima nutzen
In Davos treffen sich die Menschen, die das Geld und die Macht haben, wirklich etwas für das Klima zu bewegen: zum Beispiel, indem sie dringend nötige Investitionen in neue Technologien forcieren, oder indem sie die noch teure Technik als erste anwenden. Sie können es sich leisten.
The Case for Mandating Climate-Risk Disclosure
The US Securities and Exchange Commission is considering a proposal to require some companies to disclose information relating to the risks they face from climate change. But the agency is coming under pressure to scrap or water down the proposal because of a recent Supreme Court decision.
