Coalbed methane is an underappreciated problem of global steel production. While cutting methane emissions in the steel supply chain will not produce green steel overnight, it could reduce the sector’s emissions by the equivalent of a billion tons of carbon annually, and at little cost.
If political conditions in the United States and elsewhere require a rebranding of technologies formerly known as “climate tech,” so be it. The larger economic, technological, and geopolitical forces propelling everyone toward cleaner energy remain as strong as ever.
Just as the broader European economy depends heavily on Germany, the continent's industrial powerhouse, Germany's own economy depends on access to affordable power. With geopolitical and climate conditions requiring an urgent transition to renewables, the task now is to develop a politically viable energy strategy.
Although US President-elect Donald Trump and his fellow Republicans give climate advocates plenty to worry about, all hope is not lost. Clean-energy technologies still have decisive physical advantages over the alternatives, and economic common sense will eventually win out.
On climate and especially environmental policy, the return of Donald Trump to the White House is clearly bad news. But the outlook is uncertain, because Trump has sent mixed signals about the kinds of policy changes he might pursue, and it remains to be seen what effect he can have on broader technological and market trends.
Economists have long insisted that the only way to cut emissions of carbon dioxide and other greenhouse gases rapidly and at scale is to put a price on them. But while that is true, the key to a successful, politically sustainable climate policy is to ensure that the benefits precede the costs.
Improving energy efficiency is not enough for advocates of degrowth, who espouse energy sufficiency as the best way to fight climate change. But their argument is absurd: using limited inputs more efficiently is the definition of economic productivity – which, in turn, boosts growth.

Even if Donald Trump defeats President Joe Biden and tries to take a wrecking ball to US climate and environmental policies, he ultimately would be powerless to derail the inevitable renewables revolution that is gaining momentum worldwide. His anti-climate agenda would be another wall that never gets built.
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.
