Studying Eco-economic Decoupling

Looking Seriously at Macro Economics & Ecology

More Than Academic, a Generational Life & Death Question


Starting with Conventional Thought, Business-as-Usual

'Full-steam ahead, Capitalism, Classic Economics, Markets Rule'


Nafeez Ahmed: ‘Decoupling’ GDP growth from resource use

What conditions would enable reducing overall use of planet's resources, reduce climate change impacts *and* allow increasing, continued economic growth

Insurge / July 2020


NA / The conventional belief has been most recently articulated in a recent book, More From Less, by Andrew McAfee, principal research scientist the MIT Sloan School of Management. Financial and other data, McAfee argued, shows we can actually easily reduce our material footprint while continuing to grow our economies in a win-win scenario.


Drill down:

More From Less: The Surprising Story of How We Learned to Prosper Using Fewer Resources ― and What Happens Next

by Andrew McAfee


From critical reviews of More From Less:

This book uses falling US consumption of raw materials, energy and reducing US CO2 production to argue that resource use is decreasing despite ongoing economic growth since 1970.

Most of the consumption data referenced does not account for the fact that a large portion of US manufacturing has moved offshore in that period. Much of the data for raw material consumption is from the U.S. Geological Survey - National Minerals Information Center. I emailed them asking whether their consumption data includes imported finished goods - eg. automobiles and washing machines for steel consumption. They replied that this consumption data definitely would not. Energy consumption and CO2 production only include US based figures, ignoring the huge energy consumption and CO2 production in China which has been off shored with manufacturing our goods.

The core thesis of this book is therefore not backed up by data. I'm sure the author knows this and I think it is intellectually dishonest not to reference this in the book, especially when it is being used as a primary source of techno-optimism by Steven Pinker, Christine Lagarde, Eric Schmidt and Larry Summers.

Decoupling is a topic that has been studied extensively, with one recent overview finding over 1200 peer-reviewed research papers published between 1990 and 2015. As a result, there exists a voluminous body of research that has used better methods and covers far more ground, both theoretically and empirically, than this book. The conclusions of this research stream are fairly clear, as a recent, comprehensive and well-worth-the-read overview of decoupling research (Parrique et al. 2019) shows: while some decoupling is beyond doubt happening, there is no sturdy evidence that could permit us to believe that _necessary_ decoupling is going on.

If we wish to continue our present course and economic growth patterns, we would need to see decoupling that is 1) absolute, 2) deep enough, 3) fast enough, 4) permanent, and 5) global.

This is not what research shows, even though there is evidence that some countries have been able to slightly decrease the use of some resources (albeit even this finding diminishes once we account for the increasing financialization of the economy, as Kovacic et al. 2017 find for the EU-14).


The More From Less central message is basically demolished by a single open access article in PNAS (Wiedmann et al. 2015), not to mention other relevant research. Using far more sophisticated methods, informed by past research on the topic, and covering the value chains and countries far more extensively than this book, the Widemann et al. concluded that if the total materials footprint of industrialized countries, USA included, has decoupled at all, the amount of absolute decoupling is insignificant. I cannot find any reference to this rather fundamental piece of research in the book, nor can I find any references to any recent studies that are more critical about decoupling claims. In fact, I cannot find solid evidence, either in references or in the text, that the author is even aware that such research exists. As such, I do not believe that the book's thesis could ever be published in a reputable peer reviewed journal: existing research has already covered this ground repeatedly, with better methods.

In a positive note, the author is very clear that market fundamentalism - letting capitalism run amok - is emphatically NOT an answer to the environmental crises, and that we need a strong state to regulate and control the private interests, repair market failures and price the externalities. There is ample evidence that of all socio-economic systems we have tried so far, this approach - sometimes known as the Nordic model - has the best track record of creating and somewhat equitably distributing wealth. That said, I've already noticed that many proponents of this book haven't noticed these caveats, and instead claim that McAfee suggests unbridled capitalism is "the" answer.

However, despite rather serious flaws in the key argument, I have no doubt that the book will become a bestseller. We humans are so desperate to believe that nothing needs to change.

Nafeez Ahmed continues with his critique of those who, as with More From Less, believe that unbridled growth can be achieved alongside environmental sustainability. In other words, 'eco-economic decoupling' is possible. Ahmed's point of view is that the empirical research to date does not demonstrate viable, achievable ways to 'have it all', both environmental protection and unlimited growth.

NA / Decades of research on material flows confirm that there are “no realistic scenarios” for such decoupling going forward.

Combing through 179 of the best studies of this issue from 1990 to 2019 further reveals “no evidence” that any meaningful decoupling has ever taken place.

“The goal of decoupling rests partly on faith”, conclude the team from the BIOS Research Institute in Finland, an independent multidisciplinary scientific organisation studying the effects of environmental and resource factors on economy, politics, and culture. The BIOS team have previously advised the UN Global Sustainable Development Report on the risks of emerging biophysical limits to endless economic growth.

As the era of cheap energy comes to an end, capitalist thinking is struggling to solve the huge problems facing humanity. So how do we respond?

Raising the bar: on the type, size and timeline of a ‘successful’ decoupling

Currently the environmental impacts and resource use of many national economies is unsustainable. The only way the economy can grow or even remain at the present level is to ‘decouple’ it from these environmental impacts, thus staying within the planetary boundaries of resource use.

The problem is that many of the accounting measures used to conclude that decoupling is happening tend to systematically obscure or exclude critical data.

“The existence of decoupling in a bounded geographical area or economic sector does not, as such, mean that decoupling is happening in a wider context,” argue the UN BIOS team.

“Well-known and widely studied phenomena such as Jevons’ paradox, rebound, and outsourcing show that sectoral and local decoupling can co-exist with and even depend on increased environmental impact and increased resource use outside the analysed geographical or sectoral unit.”


Jevons Paradox

In economics, the Jevons paradox (/ˈdʒɛvənz/; sometimes Jevons effect) occurs when technological progress or government policy increases the efficiency with which a resource is used (reducing the amount necessary for any one use), but the rate of consumption of that resource rises due to increasing demand. The Jevons paradox is perhaps the most widely known paradox in environmental economics. However, governments and environmentalists generally assume that efficiency gains will lower resource consumption, ignoring the possibility of the paradox arising.

Eating the planet

The big, long picture is quite unequivocal. Global use of material resources has increased tenfold from 1900 to present, from less than 10 Gigatonnes (Gt) per year to roughly 88.6 Gt in 2017. In the decades since 1970, the rate of growth has actually accelerated, not slowed, as consumption has more than tripled.

Meanwhile, only 9–12 percent of materials are recycled, and about half of all resource use is used to provide energy in a broad sense. The other half is used for infrastructure such as buildings, transport, machines and consumer goods.

The BIOS authors find that there are certainly clear cases, limited to specific economic sectors or particular geographical regions, where we can find evidence of resource use seeming to diminish while GDP grows. But this is always linked to deepening of resource use elsewhere. The problem is that there is “no evidence of ongoing, global absolute resource decoupling.”

The situation is pretty serious. The scientists attempt to identify what genuine decoupling needs to look like, and then seek to discover whether there is any evidence that it is happening. They conclude that there is simply no viable scenario for decoupling:


“For absolute resource decoupling to make sense as a global goal, we would need a scenario where, in ca. 30 years (ca. indicates Circa – and signifies "approximately"), the economy produces 2.6 times more GDP out of every ton of material used, under conditions where material use diminishes ca. 40 percent globally. Currently, no trends corresponding to this scenario are observable and, to our knowledge, no concrete proposals with such a level of decoupling have been presented.”
