Air pollution has far-reaching effects on our climate. And efforts to curb harmful emissions are difficult and require time. Greenpeace, along with Ogilvy Hong Kong and Ogilvy Shanghai, created a print campaign to show how pollution in one place can produce harm in other far away. The campaign urges people to join Greenpeace to demand clean air in the future. If we want 2030 to look different, we have to start now.
