Four years on from nef's Growth isn’t Working, this new report goes one step further and tests that thesis in detail in the context of climate change and energy. It argues that indefinite global economic growth is unsustainable. Just as the laws of thermodynamics constrain the maximum efficiency of a heat engine, economic growth is constrained by the finite nature of our planet’s natural resources (biocapacity).

and a little video to go with it....
