BRUSSELS – The European Union is emerging as the world’s climate trailblazer. Just recently, lawmakers and European governments agreed on the European Climate Law, which anchors our climate-neutrality target in statute. With the Green Deal as our growth strategy and our 2030 emissions-reduction target of at least 55%, the EU is well on the way to achieving climate neutrality by 2050. But Europe is not alone: a critical mass is developing globally as more countries strengthen their decarbonization commitments.

Recent meetings with John Kerry, the US special presidential envoy for climate, confirmed that the EU and the United States are once again working closely to mobilize an international coalition around the goal of substantially raising climate ambitions for November’s United Nations climate summit (COP26) in Glasgow.

There is no time to lose. Unchecked climate change – with its devastating droughts, famines, floods, and mass dislocations – would fuel new migration waves and significantly increase the frequency and intensity of conflicts over water, arable land, and natural resources. To those who complain about the large investments needed to tackle climate change and biodiversity loss, we would simply point out that inaction would cost far more.

By tackling the climate and biodiversity crises, everyone will be better off, thanks to better jobs, cleaner air and water, fewer pandemics, and improved health and well-being. But, as with any broad transition, the coming changes will upset some and benefit others, creating tensions within and between countries. As we accelerate the transition from a hydrocarbon-based economy to a sustainable one based on renewable energy, we cannot be blind to these geopolitical effects.

In particular, the transition itself will drive power shifts away from those controlling and exporting fossil fuels, and toward those mastering the green technologies of the future. For example, phasing out fossil fuels will significantly improve the EU’s strategic position, not least by reducing its reliance on energy imports. In 2019, 87% of our oil and 74% of our gas came from abroad, requiring us to import more than €320 billion ($386 billion) worth of fossil-fuel products that year.

Moreover, with the green transition, the old strategic choke points – starting with the Strait of Hormuz – will become less relevant, and thus less dangerous. These seaborne passages have preoccupied military strategists for decades. But as the oil age passes, they will be less subject to competition for access and control by regional and global powers.

Phasing out energy imports will also help to reduce the income and geopolitical power of countries like Russia, which currently relies heavily on the EU market. Of course, the loss of this key source of Russian revenue could lead to instability in the near term, particularly if the Kremlin sees it as an invitation to adventurism. In the long term, though, a world run on clean energy could also be a world of cleaner government, because traditional fossil-fuel exporters will need to diversify their economies and free themselves from the “oil curse” and the corruption it so often fosters.

At the same time, however, the green transition itself will require scarce raw materials, some of which are concentrated in countries that have already shown a willingness to use natural resources as foreign-policy tools. This growing vulnerability will need to be addressed in two ways: by recycling more of these key resources, and by forging broader alliances with exporting countries.
