Energy darwinism II: why a low carbon future doesn't have to cost the earth

Up to $44 trillion could be going up in smoke if the world does not act on climate change, according to the latest piece of research from U.S. banking giant Citigroup. The report – Energy Darwinism II: Why a Low Carbon Future Doesn't Have to Cost the Earth -- has forecast that spending on energy will hit around $200 trillion in the next 25 years. The study then examines two scenarios: one that Citi describe as an "'inaction' on climate change scenario", and another that looks at what could happen if a low carbon, "different energy mix" is pursued.
