World Offset is the work of American eco-visualisation artist Tiffany Holmes, and presents itself much like a campaigning website where people pledge different actions to reduce their carbon footprint. As more pledges are made the graphic above changes, so that at certain thresholds appliances are replaced by trees. Holmes is trying to present both the futility and necessity of our small actions, and the work is itself a statement against offsetting – preferring action to purchasing emissions reductions elsewhere.
