Hugh King Energy Efficiency · © THORN Lighting2 A few quotes by way of introduction... The discussion on climate change and CO2 are dominating public debate “The climate crisis is not a political issue, it is a moral and spiritual challenge to all of humanity.” Al Gore, Nobel Peace Prize Laureate 2007 (Source: Tagesschau, ) “We do not need more words, we need action, action, action!" Appeal by Klaus Töpfer, former executive director UN Habitat, for more concrete action in the area of sustainable development
