Green growth claims overstated, according to a groundbreaking new study by researchers Marina Requena-i-Mora and Dan Brockington, which challenges the prevailing narrative of economic prosperity without increasing material consumption. Published originally in The Conversation and highlighted by Naked Capitalism, this research takes a long-term view of over 100 countries, revealing that the decoupling of economic growth from environmental pressures is not as widespread or robust as often portrayed. While some countries appear to be moving in the right direction, a deeper dive into the data uncovers significant caveats that demand a critical re-evaluation of current environmental policies.
The concept of ‘decoupling’—increasing incomes while reducing environmental pressures—has been hailed as the ‘holy grail of environmental policy.’ Indeed, initial analyses show promising trends in 25 countries, including the UK, where GDP continues to climb while material use appears to decline. However, Requena-i-Mora and Brockington’s comprehensive study, spanning 50 years for most economies and an impressive 150 years for the UK, suggests these positive indicators might be misleading. They identify three key reasons why the optimism surrounding green growth claims is overstated.
Resource Use Remains Dangerously High
The first crucial finding is that despite apparent reductions, economies are not decreasing resource use enough to reach safe planetary limits. The researchers draw an analogy to credit card debt: reducing the rate at which debt grows is an improvement, but if the debt is already substantial, the hole continues to deepen. For instance, a fair per-person share of global materials is estimated between six and eight tonnes annually. Yet, countries like the UK, Spain, Germany, and Belgium consume more than double this amount. While their material footprints are bending downwards, the starting point is so high that it’s premature to label them success stories. In stark contrast, low- and middle-income countries like Cuba and Somalia demonstrate material use within sustainable limits, albeit at lower income levels.
“To make real progress, countries consuming above a fair, sustainable share of the world’s materials – the UK among them – need to cut consumption in absolute terms, not just slow its rise.”
This highlights a critical distinction: merely slowing the increase in resource consumption is insufficient. True sustainability requires absolute reductions, especially in high-income nations. The study underscores that the current trajectory, even for ‘improving’ economies, does not align with the urgent need to operate within ecological boundaries.
No Universal Turning Point for Global Material Use
The second major revelation is the absence of a global turning point in resource consumption. Analyzing data across all 105 countries from 1970 to the present, the study consistently shows that as countries become wealthier, resource use accelerates, particularly at the highest income levels. This upward-bending shape reappears year after year, indicating that the promised downturn in material use, often associated with advanced economies, simply isn’t materializing on a global scale. This suggests that the 25 ‘success stories’ are outliers rather than harbingers of a broader trend that other nations can emulate.
Furthermore, the origins of these supposed successes are diverse and often unrelated to a ‘quiet technological revolution.’ For instance, declines in European material use largely coincide with the 2008 financial crash and subsequent housing bust. Some commodity exporters appear ‘greener’ due to high prices inflating their GDP while domestic construction remained flat. Cuba’s modest material use amidst rising GDP is attributed to decades of agroecology and urban farming. These varied historical processes—crisis, housing busts, price effects, and specific political choices—do not paint a picture of smooth technological improvement envisioned in typical green growth narratives. This lack of a consistent, replicable model further weakens the argument that green growth is a globally achievable pathway.
Historical Perspective: The Dip is Just a Blip
The third and perhaps most sobering finding emerges from a long-term historical analysis. While direct material footprint records only date back to 1970, the researchers reconstructed the UK’s material footprint all the way to 1875 using extensive historical data. This extended view dramatically alters the perception of recent trends. The ‘neat downward bend’ in material use observed since 1990 vanishes when placed within a 150-year context. Over nearly a century and a half, the relationship between British incomes and resource use is overwhelmingly an upward-sloping straight line. The current dip, therefore, appears to be a temporary ‘blip’ on a much longer upward climb, potentially a prelude to further coupled growth rather than a fundamental shift.
This historical perspective is crucial for understanding the true challenge. While efforts have been made and recent trends show some positive direction, the study questions whether these are sustained turns or mere wobbles in a larger, unsustainable pattern. The critical takeaway is that for genuine progress, countries exceeding a fair share of global materials must achieve absolute consumption cuts, not just slower growth. The examples of Cuba and Somalia demonstrate that reducing material use while incomes rise, within sustainable limits, is indeed possible. The path forward demands honest measurement of growth and resource use, over long horizons and against real ecological limits, to avoid the pitfalls of overstated green growth claims overstated by short-term or incomplete analyses. This research provides essential insights for investors and policymakers navigating the complex intersection of finance and environmental sustainability, urging a more realistic and urgent approach to climate action and economic development. Investors must recognize the inherent risks and opportunities presented by these findings, prioritizing sustainable practices that genuinely decouple prosperity from material consumption.
