How do you create a film, which needs to showcase Hitachi as a company that can help governments reverse climate change when the very process of making the film would be helping to destroy the planet? Well, we filmed the world’s first Carbon Zero Ad (not net zero, so we didn't need to offset) to make our point.

This film was narrated by Sir Sam Mendes and shown to world leaders at COP 26 (Hitachi was the principle sponsor) and beyond.
