Since 2001, 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.
guardian.co.uk has put together a photo gallery featuring 27 of the best ads. This Greenpeace ad featuring George W. Bush (remember him?), has the tagline "Everyone's entitled to an opinion. Voice yours at forum.greenpeace.org".
