Sustainability has become one of the defining ideas of modern business. It appears in annual reports, brand campaigns, and boardroom agendas with near-universal approval.
It is also, increasingly, inadequate.
For over two centuries—since the Industrial Revolution—economic progress has been built on extraction. Fossil fuels, forests, oceans, ecosystems: all treated as inputs to be consumed, optimised, and, ultimately, depleted. The consequences are no longer theoretical. Climate instability, biodiversity loss, pollution, and resource scarcity are now systemic features of the global economy.
In response, businesses and governments have turned to sustainability. The premise is simple: reduce harm. Use fewer resources. Emit less. Waste less.
It is a rational response. It is also a fundamentally limited one.
Because “less bad” is not the same as good.
Consider Earth Overshoot Day—the point each year when humanity’s demand for natural resources exceeds what the planet can regenerate in that same year. In 2020, that date fell on 22 August. Everything consumed after that point—over a third of annual resource use—was effectively borrowed from the future.
And 2020, distorted by a global slowdown in economic activity, was an anomaly. In most years, the threshold is crossed even earlier.
For more than half a century, humanity has been operating in ecological deficit.
Against that backdrop, sustainability begins to look less like a solution and more like a mitigation strategy. It slows the rate of damage, but it does not reverse it. Even in a hypothetical scenario where businesses achieve “net zero” harm, the accumulated deficit remains.
Decades of extraction do not disappear because the rate of extraction stabilises.
This is the central flaw in the sustainability paradigm: it is designed to preserve systems that are already failing.
The language itself reveals the limitation. To sustain is to maintain. To keep things at a certain level. But what, exactly, are we trying to sustain? An equilibrium that no longer exists? A baseline that has already been eroded?
If the system is degraded, sustaining it simply locks in that degradation.
This is why a growing number of thinkers and practitioners are shifting the conversation towards regeneration.
Where sustainability seeks to minimise harm, regeneration seeks to create net positive impact. It is not about maintaining the current state of play, but about restoring and renewing the systems on which business—and life—depend.
As Carol Sanford argues, in her book “The Regenerative Business”, the problem with sustainability is that it keeps organisations focused on improving what already exists. It encourages optimisation of the current system, rather than reimagining it. The result is incremental progress in a context that demands structural change.
Regeneration operates differently. It starts from a more fundamental question: not how to do things better, but how to do better things.
This distinction is critical.
Sustainability initiatives tend to be reactive—reducing emissions, cutting waste, improving efficiency. Regenerative approaches are generative—designing products, systems, and business models that actively restore ecosystems, replenish resources, and strengthen the environments in which they operate.
One is about reduction. The other is about renewal.
The implication for business is significant. Regeneration is not a bolt-on initiative or a corporate responsibility programme. It requires a rethinking of value creation itself—how materials are sourced, how products are designed, how success is measured.
It is more demanding. It is also more aligned with the scale of the challenge.
None of this is to dismiss sustainability entirely. It has played an important role in raising awareness and establishing accountability. Without it, the current situation would almost certainly be worse.
But its limitations are now visible.
In a world operating beyond its ecological means, incremental improvement is no longer sufficient. Slowing the rate of decline is not the same as reversing it.
The question facing business is no longer how to be less harmful.
It is how to be actively restorative.
Which is why the language—and the ambition—must evolve.
From sustainability to regeneration.
Because the future will not be secured by doing less damage.
It will be secured by repairing what has already been done—and designing systems that make that repair continuous.
