According to Kia, each brick “[emphasizes] the striking and inspiring design of the EV6, while also conveying the notion that the future of sustainable mobility is to be built ‘brick by brick.'”
It’s corny PR, but the point is sound. Not even the Lego bricks used are made of sustainable or even recyclable materials, and the core materials used to build EVs are far from sustainable. Lego has set a course to be sustainable by 2030 and has even prototyped recycled bricks, but EVs are the big concern.
The point that gets missed by people pointing at things like lithium mining is that no technology and its production come fully formed out of the box. It’s going to be a long process, but the quickest summation is that EVs give us emissions-free transport, and automakers are working backward from there.
