Is it possible to address the environmental crises we face while continuing to pursue economic growth? I draw on several pieces referenced by Spencer Bokat-Lindell in his excellent article for The New York Times reviewing the green growth vs. degrowth debate as well as some other sources.
Economic growth—as measured by the indicator Gross Domestic Product (GDP)— has led to exceptional material prosperity, remarkable technologies, and great advancements in health. To take one example, in a Vox article, Kelsey Piper notes that there is a strong correlation between low child mortality and high GDP per capita. But the effects of the growth-focused economic system are not all positive. The growth model has steamrolled alternative economic, and often political, systems, reshaping the whole world in the image of the Global North. There is massive economic inequality, both within and between countries, and many people are unable to meet their basic needs. And most relevant to the question of whether growth can be environmentally sustainable, the growth-focused model has led to environmental crises, including climate change and biodiversity loss, which threaten the planet’s life support systems.
The prevailing approach to addressing environmental crises is known as green growth. Proponents of green growth argue that it is possible to continue growing GDP while also reducing material and energy use and quickly reaching net zero carbon emissions. However, some environmentalists have championed an alternative approach known as degrowth. In a journal article, degrowth proponent Jason Hickel writes, “Degrowth is a planned reduction of aggregate resource and energy use in high-income nations designed to bring the economy back into balance with the living world in a safe, just and equitable way.” Indeed, advocates argue that degrowth is necessary to bring the economy and the planet into balance. Hickel and Giorgos Kallis write in a review of empirical studies of green growth:
“extant empirical evidence does not support the theory of green growth. This is clear in two key registers. (1) Green growth requires that we achieve permanent absolute decoupling of resource use from GDP. Empirical projections show no absolute decoupling at a global scale, even under highly optimistic conditions. While some models show that absolute decoupling may be achieved in high-income nations under highly optimistic conditions, they indicate that it is not possible to sustain this trajectory in the long term. (2) Green growth also requires that we achieve permanent absolute decoupling of carbon emissions from GDP, and at a rate rapid enough to prevent us from exceeding the carbon budget for 1.5°C or 2°C. While absolute decoupling is possible at both national and global scales (and indeed has already been achieved in some regions), and while it is technically possible to decouple in line with the carbon budget for 1.5°C or 2°C, empirical projections show that this is unlikely to be achieved, even under highly optimistic conditions.”
In other words, Hickel and Kallis argue that evidence shows that a growing economy will, first, use more natural resources than is sustainable and, second, likely fail to make the transition away from carbon emissions quickly enough to meet the Paris Agreement targets. For these authors, green growth is an illusion.
(On climate change, a key issue is whether it is appropriate to employ bioenergy with carbon capture and storage (BECCS). Hickel and Kallis write that BECCS “entails growing large tree plantations to sequester CO2 from the atmosphere, harvesting the biomass, burning it for energy, capturing the CO2 emissions at source and storing it underground.” The authors make the case that BECCS is unproven and potentially damaging for people and the planet.)
The social dimension of degrowth is crucial. While high-income countries would switch from a growth-based economic model, low- and medium-income countries would continue to grow their economies until a greater level of wealth is reached. And within high-income countries, degrowth advocates support policies such as job and income guarantees, decommodification of public goods, and democratization of the economy. The premise is that policies like these would prevent a drop in GDP from causing the economic pain and decreased wellbeing that occurs when growth-based economies enter recessions.
As the degrowth argument has gained traction, advocates of green growth have pushed back. Here, I will highlight two critiques of degrowth.
One argument is that degrowth is not politically feasible. Either degrowth will always be a losing battle in high-income countries or, while it may eventually attract enough support to be politically possible, this consensus will not be built in the vanishingly short amount of time we have left to address climate change. Spencer Bokat-Lindell quotes Eric Levitz of New York magazine:
“’Americans might well find themselves happier and more secure in an ultra-low-carbon communal economy in which individual car ownership is heavily restricted, and housing, health care, and myriad low-carbon leisure activities are social rights.’ But, he adds, ‘nothing short of an absolute dictatorship could affect such a transformation at the necessary speed. And the specter of eco-Bolshevism does not haunt the Global North. Humanity is going to find a way to get rich sustainably, or die trying.'”
A second argument is that due to the interconnectedness of the global economy, economic contraction in high-income countries would hamper economic growth in low- and middle-income countries. In the Vox article mentioned earlier, Kelsey Piper writes:
“the pandemic offered a taste of how a sudden drop in rich-world consumption would actually affect the developing world. Covid-19 dramatically curtailed Western imports and tourism for a time. The consequences in poor countries were devastating. Hunger rose, and child mortality followed….
Hickel’s perspective is that most trade between rich and poor countries is extractive, not mutually beneficial — and that maybe when that dynamic ceases, poor countries will have the chance for the catch-up growth they merit. That’s one take. But it means that degrowth’s case for not crushing the poor world is predicated on a speculative take on how those countries can grow — one that democratically elected leaders in those countries largely don’t share.”
If it is true that a decrease in imports by high-income countries would inevitably harm low- and middle-income countries, this undermines degrowth’s commitment to just social outcomes.
As the green growth/degrowth debate rages on, there have been attempts to “reach a truce…” In an article for openDemocracy, Beth Stratford argues that both sides should reach a consensus “on a basic set of demands that can stop us hurtling toward ecological collapse.”
Additionally, degrowth is not the only framework that challenges the growth-based model. Another framework, called doughnut economics, was developed by Kate Raworth. The principle of doughnut economics is that economies’ resource use should be sufficient to meet everyone’s needs without destroying the Earth’s life support systems. Right now, the problem is that “millions or billions of people worldwide still fall short on their most basic of needs” while “we’ve already overshot at least four… planetary boundaries…” For Raworth, it’s necessary to “overcome this structural dependency on growth, so that we can instead focus on thriving and balance within the social and the ecological boundaries of the doughnut.”
The question of whether it is possible to create a just, sustainable world through green growth or whether it is necessary to move to something like degrowth or doughnut economics is complicated and deserves careful consideration. But I think this is precisely the conversation we need to have. And right now, both supporters and opponents of green growth should find where they agree and push for meaningful changes in social and environmental policy.
