Challenge

Transport for London needed to build public support for the introduction of the Ultra Low Emission Zone (ULEZ). The policy would improve air quality by charging the most polluting vehicles every time they entered central London, but the expected public backlash was enormous, with many drivers seeing it as little more than another tax on motorists.

Strategic Unlock

For most Londoners, air pollution had become the invisible price of living in a big city. Adults may be prepared to accept that trade-off for themselves, but very few are comfortable making it on behalf of their children. By reframing air pollution as a children's health issue rather than an environmental one, we turned an abstract policy debate into a deeply personal choice.

Creative Solution

We made the invisible visible by showing the hidden impact polluted air was having on London's youngest residents. Instead of talking about emissions, legislation or climate change, the campaign focused on the children breathing that air every day, reminding Londoners that the real cost of pollution wasn't measured in parts per million, but in young lungs. The campaign gave the Ultra Low Emission Zone a human reason to exist.
