Saving and greening European steel mills is now a key part of the EU’s defense strategy.

BRUSSELS — The EU needs to build more tanks — and there’s no reason why those tanks can’t be green.

In a bid to save its decaying steel and metal industries, the EU has formulated a plan to protect the sector against unfair competition from abroad, high energy prices and a looming trade war with the U.S. — all while helping it go green.

With this strategy — which is largely based on leveraging the EU’s arsenal of trade measures against cheaper foreign products and subsidizing the sector’s decarbonization — Brussels is hoping that saving metals manufacturing will also boost the defense industry and ultimately, keep Europe safe.

“A main battle tank contains 50 to 60 tonnes of high-quality steel, a self-propelled artillery system, up to 100 tonnes, a fighter aircraft 3 tonnes of aluminium,” the Commission writes in the plan, adding that “a stable and resilient supply chain for these materials is critical to strengthening the European Defence Technological and Industrial Base, ensuring the EU’s preparedness and internal security.”
