Greenpeace asked for a big, bold idea to get the UK marching alongside school climate strikers. We created #TICKTOCK to tell them the time for action was now. ​

A guerrilla project launched in September 2019, we projected our message across UK landmarks.

Activists, artists and celebrities joined the movement. Then on the day of the march, we staged a one-minutes noise, alarm clock protest. It was the biggest-ever environmental protest the UK had seen, with 300,000-350,000 taking part, including more than 100,000 people in London
