Gearing up for a 10% reduction is an ambitious goal from the perspective of human convenience, but not when we consider the real threat of runaway climate change. The highest concentration of carbon dioxide in the atmosphere that most scientists consider safe is 350 parts per million. The concentration right now is around 380 and rising.
Global 10% reduction would bring us back from the brink.
Local 10% reduction shows that people care, and can organize to take meaningful action.
The 10% Challenge is an invitation to creative redesign of our lifestyles, work routines, and communities. The real transformation is in getting 10% of our people involved, developing energy-savvy local leadership for the future.
