Nice project from China: »The China Environmental Protection Foundation developed an outdoor campaign, displayed on the street, to creatively promote this message. They decided to leverage a busy pedestrian crossing; a place where both pedestrians and drivers meet.
The campaign involved laying a canvas 12.6 metres long by 7 metres wide on the ground, thus covering the pedestrian crossing with a large leafless tree. On either side of the road, beneath the traffic lights, were placed sponge cushions soaked in green, environmentally friendly, washable paint. As pedestrians walked towards the crossing, they stepped on the green sponge, thus leaving green foot imprints on the canvas of the tree. Each „green“ footprint on the canvas looked like leaves growing on a bare tree, which made people feel that by walking they could create a greener environment.«
