Capitalism’s Environmental Impact: Understanding the Treadmill of Production

Every economy on Earth runs on a simple promise: grow more, produce more, consume more. But what happens when this relentless drive for expansion collides with a planet that has finite resources? The relationship between capitalism and environmental degradation isn’t just a philosophical debate – it’s a measurable, observable crisis shaping our climate, our ecosystems, and our future. To understand why environmental problems persist despite decades of awareness and policy efforts, we need to examine the structural forces at play.

The treadmill of production theory 🔗

In 1980, sociologist Allan Schnaiberg introduced a concept that has since become one of the most influential frameworks in environmental sociology: the treadmill of production. The core idea is straightforward. Capitalist economies are locked into a self-reinforcing cycle of ever-increasing production and consumption, and this cycle inevitably leads to greater environmental harm.

Schnaiberg argued that the system operates through two key mechanisms. The first is ecological withdrawals – the extraction of raw materials from the natural environment to fuel production. Think of mining, deforestation, water extraction, and fossil fuel drilling. The second is ecological additions – the waste, pollution, and emissions that production processes dump back into the environment. Together, these two forces create a continuous loop of environmental degradation.

Why the treadmill keeps spinning 🔗

What makes the treadmill so difficult to stop is the alignment of interests among three major social groups: corporations, workers, and the state. Corporations need continuous growth to generate profits and satisfy investors. Workers depend on expanding industries for employment and wages. And governments rely on economic growth for tax revenue, political legitimacy, and social stability. This tripartite support system keeps the treadmill running even when the environmental costs become painfully obvious.

Schnaiberg connected this dynamic specifically to monopoly capitalism, drawing on the work of economists like Paul Baran and Paul Sweezy. In his view, the concentration of economic power in large corporations intensified the treadmill effect because these firms had the political influence to resist environmental regulation and the economic power to expand production on a massive scale. The treadmill, in other words, isn’t an accident or a policy failure – it’s a structural feature of how capitalist economies operate.

The environmental cost of economic growth 🔗

The treadmill of production isn’t just a theory. Its effects are visible in hard data. According to the UNEP Global Resources Outlook 2024, global resource extraction has tripled since 1970, rising from about 30 billion tonnes to 106 billion tonnes by 2020. Without significant intervention, extraction could increase by another 60% by 2060.

Resource depletion at an unprecedented scale 🔗

The sheer volume of materials flowing through the global economy illustrates Schnaiberg’s concept of ecological withdrawals. Biomass harvesting, mining of metals and minerals, fossil fuel extraction, and quarrying of construction materials are all increasing to feed expanding production systems. The International Resource Panel found that extraction and processing of fossil fuels, metals, and non-metallic minerals together account for roughly 35% of global greenhouse gas emissions. Agricultural production, meanwhile, is responsible for about 90% of land-related biodiversity loss and water stress.

This isn’t simply a matter of population growth. Wealthy nations consume six times more materials and generate ten times the climate impact compared to low-income countries. The pattern reflects exactly what treadmill theory predicts: production intensifies where capital accumulates, and the environmental costs are distributed unevenly.

Pollution and greenhouse gas emissions 🔗

On the ecological additions side, the picture is equally concerning. Manufacturing processes release toxic chemicals, heavy metals, and greenhouse gases into air, water, and soil. As the World Economic Forum has noted, greenhouse gas emissions have accelerated sharply since the mid-1990s, driven primarily by strong economic growth in developing countries relying on non-renewable natural resources. These resources tend to be systematically underpriced because their future scarcity and environmental costs aren’t factored into market prices.

The climate crisis is perhaps the clearest illustration of the treadmill in action. The global average temperature in 2023 was approximately 1.54°C above pre-industrial levels, making it the warmest year on record. Despite decades of climate negotiations and pledges, global emissions continue to rise because the economic system’s fundamental demand for growth outpaces efficiency improvements and policy interventions.

The externality problem 🔗

A key insight from both Schnaiberg’s framework and mainstream economics is that capitalism tends to treat environmental damage as an externality – a cost that isn’t reflected in the price of goods and services. When a factory pollutes a river, the cost of that pollution falls on downstream communities, not on the company’s balance sheet. When carbon dioxide is released into the atmosphere, the costs of climate change are spread across the entire planet and across future generations.

This creates a fundamental misalignment. Firms are compelled by market competition to cut costs, and projecting those costs onto the environment is one of the easiest ways to do so. Without non-market intervention – through regulation, taxation, or collective action – the market provides no mechanism to prevent this behaviour.

Can we break the cycle? 🔗

If the treadmill of production is structural rather than accidental, breaking the cycle requires more than individual consumer choices or marginal policy tweaks. Several alternative frameworks have been proposed, each with different implications for how economies and societies would need to change.

Sustainable development and green growth 🔗

The most mainstream approach is sustainable development, which emerged from the 1992 Earth Summit and has been championed by institutions like the OECD, the World Bank, and the United Nations Environment Programme. The idea is that economic growth can be made environmentally sustainable through technological innovation, improved efficiency, and market-based mechanisms like carbon pricing and emissions trading.

There have been real achievements under this framework. Renewable energy costs have plummeted, electric vehicles are becoming mainstream, and some countries have managed to partially decouple GDP growth from emissions. The UNEP’s 2024 report suggests that ambitious policy shifts – including resource efficiency measures and circular economy models – could peak global resource extraction by 2040 while still growing the economy.

However, critics point to a persistent problem: efficiency gains often lead to rebound effects. When a product becomes cheaper to produce, consumption tends to increase, partially or fully offsetting the environmental savings. This is sometimes called the Jevons paradox, and it suggests that efficiency alone may not be enough to break the treadmill.

Degrowth: rethinking the growth imperative 🔗

A more radical alternative is the degrowth movement, which directly challenges the assumption that economic growth is necessary or desirable in wealthy nations. Degrowth advocates argue that the environmental crisis cannot be solved within a system that demands perpetual expansion. Instead, they call for a planned, democratic reduction of production and consumption in affluent economies, combined with redistribution of resources to the Global South.

Degrowth isn’t simply about shrinking the economy. It envisions a reorganisation of society around different priorities: shorter working hours, stronger community institutions, care-based rather than growth-based economics, and local production systems. Practical experiments – including community currencies, housing cooperatives, urban food gardens, and renewable energy cooperatives – already embody some of these principles.

The IPCC and IPBES have both acknowledged that degrowth policies should be considered in the fight against climate change and biodiversity loss. However, degrowth faces significant practical challenges. In a globally interconnected economy, any country attempting to reduce growth unilaterally risks capital flight, currency instability, and political isolation. A meaningful degrowth transition would need to be coordinated internationally – a daunting political task.

The role of environmental policy and regulation 🔗

Regardless of whether one favours green growth or degrowth, strong environmental policy is essential to slowing the treadmill. Key policy instruments include:

Carbon pricing and emissions caps force companies to internalise the environmental costs of their activities, making pollution more expensive and cleaner alternatives more competitive. Resource efficiency standards can reduce the material throughput of economies without necessarily reducing output. Circular economy regulations aim to keep materials in use for longer, reducing both extraction and waste. Subsidy reform – particularly removing subsidies for fossil fuels – can shift investment toward sustainable alternatives.

The challenge, as Schnaiberg’s theory predicts, is that powerful economic actors often resist these policies. Governments dependent on growth for political stability are reluctant to impose regulations that might reduce corporate profits or slow economic expansion. This is why environmental sociologists emphasise the role of social movements and organised civil society in pressuring both states and corporations to act.

Ecosocialism and systemic alternatives 🔗

Some scholars go further, arguing that meaningful environmental protection requires a fundamental transformation of the economic system itself. Ecosocialism proposes greater public ownership and democratic control over key economic sectors – particularly energy, transport, and land use – to ensure that production decisions prioritise ecological sustainability over private profit. Others advocate for frameworks like doughnut economics, which seeks to meet everyone’s basic needs without overshooting planetary boundaries.

These approaches remain politically contentious. But they reflect a growing recognition that the treadmill of production cannot be stopped simply by adjusting the speed – the mechanism itself may need to be redesigned.

Why this matters now 🔗

Schnaiberg developed his treadmill theory in the late 1970s, but it is arguably more relevant today than ever. Global supply chains have extended the treadmill’s reach across the entire planet, with environmental degradation in developing countries occurring as a direct result of production demand from wealthier nations. The richest 10% of the global population are responsible for nearly twenty times more emissions than the poorest 50%.

At the same time, the window for meaningful action is narrowing. Six of nine planetary boundaries have already been exceeded, and current policy commitments fall far short of what’s needed to limit warming to 1.5°C. The treadmill theory reminds us that these aren’t just technical problems waiting for technical solutions. They are deeply rooted in the structure of our economic system, and addressing them will require structural changes to match.

Understanding the treadmill of production doesn’t mean abandoning all hope. It means being clear-eyed about the scale of the challenge. Individual actions matter, but they aren’t sufficient. Policy interventions are necessary, but they face powerful resistance. Systemic alternatives exist, but they require political will and collective mobilisation. The first step is understanding why the treadmill keeps spinning – and then deciding what kind of economy we actually want to build.

What do you think? Is it realistic to pursue environmental sustainability within a growth-driven economic system, or does genuine ecological protection require moving beyond the growth imperative altogether? How can societies balance the legitimate need for economic security and employment with the urgent need to reduce resource consumption and emissions?
