How Do You Degrow An Economy, Without Causing Chaos?

Jonathan Rutherford

‘Houston, we have a problem’. On the one hand, there is growing acceptance among environmentally conscious people that rich nations and affluent regions of the global economy must dramatically reduce overall resource and energy consumption levels – that is, undergo a process of ‘degrowth’ – if humanity is to bring about a sustainable world order. On the other hand, we have a growth economy that cannot go two steps in this direction without causing huge economic and social problems.

If you doubt the first part of this statement (i.e. the need for ‘degrowth’), consider just one metric – the material footprint (MF) indicator. This measures consumption of all natural resources (biomass, fossil fuels, metal ores and minerals) extracted from the environment. Humanity’s current MF is about 70 billion tonnes – a figure that has more than trebled since the 1970s. As we know, already this rate of consumption is generating waste, pollution and land-use change that are driving environmental problems such as global warming and species extinction. But now consider the fact that the per capita rich nation (i.e OECD) MF is about 30 tonnes. If the 9+ billion humans expected to be living on earth by 2050 rose to this level, we would need 270 billion tonnes per annum – that is, four times the present rate, which is unsustainable.
