Why Growth Can't Be Green.

By Jason Hickel, Jason, Foreign Policy, Fall 2018

WARNINGS ABOUT ECOLOGICAL BREAKDOWN have become ubiquitous. Over the 
past few years, major newspapers, including the Guardian and the New 
York Times, have carried alarming stories on soil depletion, 
deforestation, and the collapse of fish stocks and insect populations. 
These crises are being driven by global economic growth, and its 
accompanying consumption, which is destroying the Earth's biosphere and 
blowing past key planetary boundaries that scientists say must be 
respected to avoid triggering collapse.

Many policymakers have responded by pushing for what has come to be 
called "green growth." All we need to do, they argue, is invest in more 
efficient technology and introduce the right incentives, and we'll be 
able to keep growing while simultaneously reducing our impact on the 
natural world, which is already at an unsustainable level. In technical 
terms, the goal is to achieve "absolute decoupling" of GDP from the 
total use of natural resources, according to the U.N. definition.

It sounds like an elegant solution to an otherwise catastrophic problem. 
There's just one hitch: New evidence suggests that green growth isn't 
the panacea everyone has been hoping for. In fact, it isn't even possible.

Green growth first became a buzz phrase in 2012 at the United Nations 
Conference on Sustainable Development in Rio de Janeiro. In the run-up 
to the conference, the World Bank, the Organization for Economic 
Cooperation and Development, and the U.N. Environment Program all 
produced reports promoting green growth. Today, it is a core plank of 
the U.N. Sustainable Development Goals.

But the promise of green growth turns out to have been based more on 
wishful thinking than on evidence. In the years since the Rio 
conference, three major empirical studies have arrived at the same 
rather troubling conclusion: Even under the best conditions, absolute 
decoupling of GDP from resource use is not possible on a global scale.

A team of scientists led by the German researcher Monika Dittrich first 
raised doubts in 2012. The group ran a sophisticated computer model that 
predicted what would happen to global resource use if economic growth 
continued on its current trajectory, increasing at about 2 to 3 percent 
per year. It found that human consumption of natural resources 
(including fish, livestock, forests, metals, minerals, and fossil fuels) 
would rise from 70 billion metric tons per year in 2012 to 180 billion 
metric tons per year by 2050. For reference, a sustainable level of 
resource use is about 50 billion metric tons per year—a boundary we 
breached back in 2000.

The team then reran the model to see what would happen if every nation 
on Earth immediately adopted best practice in efficient resource use (an 
extremely optimistic assumption). The results improved; resource 
consumption would hit only 93 billion metric tons by 2050. But that is 
still a lot more than we're consuming today. Burning through all those 
resources could hardly be described as absolute decoupling or green growth.

In 2016, a second team of scientists tested a different premise: one in 
which the world's nations all agreed to go above and beyond existing 
best practice. In their best-case scenario, the researchers assumed a 
tax that would raise the global price of carbon from $50 to $236 per 
metric ton and imagined technological innovations that would double the 
efficiency with which we use resources. The results were almost exactly 
the same as in Dittrich's study. Under these conditions, if the global 
economy kept growing by 3 percent each year, we'd still hit about 95 
billion metric tons of resource use by 2050. Bottom line: no absolute 

Finally, last year the U.N. Environment Program—once one of the main 
cheerleaders of green growth theory—weighed in on the debate. It tested 
a scenario with carbon priced at a whopping $573 per metric ton, slapped 
on a resource extraction tax, and assumed rapid technological innovation 
spurred by strong government support. The result? We hit 132 billion 
metric tons by 2050. This finding is worse than those of the two 
previous studies because the researchers accounted for the "rebound 
effect," whereby improvements in resource efficiency drive down prices 
and cause demand to rise—thus canceling out some of the gains.

Study after study shows the same thing. Scientists are beginning to 
realize that there are physical limits to how efficiently we can use 
resources. Sure, we might be able to produce cars and iPhones and 
skyscrapers more efficiently, but we can't produce them out of thin air. 
We might shift the economy to services such as education and yoga, but 
even universities and workout studios require material inputs. Once we 
reach the limits of efficiency, pursuing any degree of economic growth 
drives resource use back up.

These problems throw the entire concept of green growth into doubt and 
necessitate some radical rethinking. Remember that each of the three 
studies used highly optimistic assumptions. We are nowhere near imposing 
a global carbon tax today, much less one of nearly $600 per metric ton, 
and resource efficiency is currently getting worse, not better. Yet the 
studies suggest that even if we do everything right, decoupling economic 
growth with resource use will remain elusive and our environmental 
problems will continue to worsen.

Preventing that outcome will require a whole new paradigm. High taxes 
and technological innovation will help, but they're not going to be 
enough. The only realistic shot humanity has at averting ecological 
collapse is to impose hard caps on resource use, as the economist Daniel 
O'Neill recently proposed. Such caps, enforced by national governments 
or by international treaties, could ensure that we do not extract more 
from the land and the seas than the Earth can safely regenerate. We 
could also ditch GDP as an indicator of economic success and adopt a 
more balanced measure like the genuine progress indicator (GPI), which 
accounts for pollution and natural asset depletion. Using GPI would help 
us maximize socially good outcomes while minimizing ecologically bad ones.

But there's no escaping the obvious conclusion. Ultimately, bringing our 
civilization back within planetary boundaries is going to require that 
we liberate ourselves from our dependence on economic growth—starting 
with rich nations. This might sound scarier than it really is. Ending 
growth doesn't mean shutting down economic activity—it simply means that 
next year we can't produce and consume more than we are doing this year. 
It might also mean shrinking certain sectors that are particularly 
damaging to our ecology and that are unnecessary for human flourishing, 
such as advertising, commuting, and single-use products.

But ending growth doesn't mean that living standards need to take a hit. 
Our planet provides more than enough for all of us; the problem is that 
its resources are not equally distributed. We can improve people's lives 
right now simply by sharing what we already have more fairly, rather 
than plundering the Earth for more. Maybe this means better public 
services. Maybe it means basic income. Maybe it means a shorter working 
week that allows us to scale down production while still delivering full 
employment. Policies such as these—and countless others—will be crucial 
to not only surviving the 21st century but also flourishing in it.
