Lego has opened a $1 billion factory in Vietnam that it says will make toys without adding planet-warming gas to the atmosphere by relying entirely on clean energy.

With solar panels, battery storage, and sustainable packaging, Lego’s new Vietnam factory is a bold step toward a net-zero future.

Toymaker Lego has opened a new factory in southern Vietnam, it said on Wednesday, as the company aims for long-term growth in the Asia Pacific region and to move production closer to its consumers.
