All rights reserved. ‘Decoupling of global emissions and economic growth confirmed’ ran the headline on the International Energy Agency (IEA) website in March 2016. “Coming just a few months after the landmark COP21 agreement in Paris, this is yet another boost to the global fight against climate change”, noted IEA Executive Director Fatih Birol. It’s a popular idea that the decoupling of economic growth and carbon emission represents ‘green growth’ or ‘sustainable growth’, and that this is a powerful tool in the fight against dangerous levels of climate change. The idea was further pushed in a 2014 report co-authored by prominent economist Lord Stern, and backed by the United Nations, the OECD, the International Monetary Fund and the World Bank.
Dr Samuel Alexander, Co-Director of the Simplicity Institute and a Research Fellow with the Melbourne Sustainable Society Institute, has written a number of articles critiquing the idea of decoupling. I interviewed him to find out why, and what solutions he proposes to the threat of climate change.
Ian Sinclair: What is the thinking of those who herald ‘decoupling’ as a promising tool in stopping dangerous levels of climate change? Why do you think it has proven such a popular idea?
Samuel Alexander: Decoupling (or dematerialization) refers to the idea of increasing our economic output without increasing or even decreasing energy and resource inputs. We should at once distinguish between ‘relative’ decoupling and ‘absolute’ decoupling. The former refers to a reduction of inputs (resources) per unit of output (GDP). The latter refers to an absolute or overall reduction of inputs. If an economy expands faster than the efficiency gains it may achieve, it is possible for there to be relative decoupling without absolute decoupling. With respect to climate change, the idea or hope of decoupling is that we can continue growing our economies while reducing total carbon emissions to a safe level.
Decoupling can be achieved by technological or design innovation that helps us produce our commodities more efficiently, or through market mechanisms that price fossil fuels in a way that disincentivises their consumption and incentivises the production of low-emission or no-emission alternatives.
This strategy for combating climate change is so popular because it suggests that we don’t really have to re-think the dominant economic paradigm of growth, or change our lifestyles much. That is, by way of decoupling, it is widely believed that we will be able to keep growing our economies without limit, and continue living high-consumption lifestyles, while absolutely decoupling that economic activity from fossil fuels.
It’s a nice idea, perhaps, but the theoretical possibility of absolute decoupling (which is required) doesn’t have much empirical support in reality. It’s a strategy that has been talked about for decades, all the while carbon emissions have continued to grow. There have been no long term reductions in emissions other than during times of recession or depression. But people continue to put so much faith in decoupling because it is non-confronting. It allows politicians to claim that they’re pursuing environmentally progressive policies, even though history suggests it is a strategy that doesn’t work. It allows consumers to go on consuming, trusting that soon our consumption practices will be decoupled from carbon emissions. This is a dangerous myth.
