London, U.K.

Since 2001, the Swiss-based not-for-profit organisation ACT Responsible (Advertising Community Together), has been collecting global advertising that “promotes responsible communication on sustainability, equitable development and social responsibility” in a bid to highlight how the creativity of advertising professionals can be used to address the world’s problems.

Among its 2,500 ads from more than 40 countries and 140 award-winning agencies is a striking collection of adverts that focus on environmental and social issues: from deforestation to recycling and conserving water to climate change.

Ads, from the top: Killing trees is killing people. for Friends of the Earth, France; Travelling fruits cause pollution. (Think global. Eat local.)  for Bund/Friends of the Earth, Germany; A single tin of paint can pollute millions of liters of water. for WWF Spain; Forests for Life. for WWF Thailand; Save. for WWF Hungary.
