Turning plastic waste into a ballot
As world leaders negotiate a global plastics treaty, WWF calls on everyone to act. The crisis is massive, but we can all demand that those responsible for the pollution are held accountable.Ahead of the negotiations for a global plastics treaty, WWF needed to raise awareness of a problem that is steadily increasing, and direct attention toward those who can make a real and meaningful difference. The issue has become so large and complex that people may feel powerless to act. But one concrete thing everyone can do is to demand that those who can stop the pollution take greater responsibility.
As part of the campaign, we placed interactive trash bins at Norway’s busiest location, allowing people to physically sort their waste to the parties they believe hold the greatest responsibility.
