What Is Our Common Future Now?
Our Common Future Now is a book about sustainability, but it did not begin as a book about answers.
It began as an inquiry.
After nearly forty years of sustainability strategies, targets, frameworks, reporting systems, standards, innovation programs and corporate commitments, one question remains difficult to avoid:
Why has real sustainability transformation remained so elusive?
This is not a question about whether people have tried. Many have. Governments, companies, NGOs, academics, consultants, investors and communities have spent decades working to make business and society more sustainable.
There has been no shortage of activity.
And yet many of the conditions required to sustain life continue to deteriorate.
That tension sits at the heart of Our Common Future Now.
Returning to the Beginning
In 1987, the World Commission on Environment and Development published Our Common Future, often called the Brundtland Report.
Most people know the report through one sentence:
“Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
That sentence became one of the most repeated ideas in sustainability.
But there is a problem.
It is not a definition of sustainability. It is a definition of sustainable development.
That distinction matters.
Over time, much of the sustainability field appears to have treated sustainable development and sustainability as if they were the same thing. They are related, but they are not identical. Development is a human activity. Sustainability is a condition of continuity over time.
If those two ideas are collapsed into one another, the field may begin asking the wrong questions without realizing it.
Our Common Future Now revisits that starting point and asks what may have been simplified, overlooked or distorted as sustainability moved from a global inquiry into a professional field.
The Central Question
The central question of the book is not simply:
How do we become more sustainable?
It is:
What are we actually trying to sustain, for how long, and under what conditions?
That question changes the inquiry.
It moves sustainability away from vague aspiration and toward the requirements of enduring systems. It asks whether our definitions, models and strategies are sufficient to describe the reality we claim to be addressing.
It also challenges a familiar assumption: that more sustainability activity automatically means progress toward sustainability.
Activity matters. But activity is not the same as transformation.
A company can produce reports, set targets, redesign products, improve efficiency and pursue circularity without necessarily resolving the deeper question of whether its activities are compatible with the long-term conditions required for life, business and society to continue.
Why the Book Matters Now
The timing matters because sustainability is approaching a new phase.
For decades, the field has been shaped by inherited language: sustainable development, the three pillars, ESG, circular economy, net zero, regeneration, resilience and many other frameworks.
Some of these ideas are useful. Some are incomplete. Some may have become so familiar that they are rarely questioned.
Now artificial intelligence is beginning to learn from and reproduce that accumulated body of knowledge.
That raises a new risk.
If AI systems are trained on decades of sustainability assumptions, they may repeat those assumptions with speed, fluency and confidence. They may make conventional wisdom appear even more authoritative, even when the underlying concepts deserve closer examination.
This is one reason the inquiry behind Our Common Future Now matters beyond the book itself.
The question is no longer only whether humans have inherited simplified ideas about sustainability.
The question is also whether AI will amplify them.
What the Book Argues
Our Common Future Now does not argue that sustainability should be abandoned.
It argues the opposite.
It suggests that sustainability may need to be taken more seriously than many of our current frameworks allow.
That means returning to first principles. It means distinguishing sustainability from sustainable development. It means asking whether circularity is always sustainable, whether business sustainability and environmental sustainability are the same kind of problem, and whether familiar models have hidden limitations.
The book examines belief pairs, assumptions and recurring patterns that may have shaped the field for decades. Its purpose is not to assign blame. Its purpose is to make the assumptions visible.
Once assumptions become visible, they can be tested.
And once they can be tested, better questions become possible.
A Book About Looking Again
At its core, Our Common Future Now is an invitation to look again.
To look again at the Brundtland Report.
To look again at the language of sustainability.
To look again at circularity, business, development, growth, continuity and compatibility.
To look again at what we think we already know.
That may be the most practical starting point available now.
Because if sustainability has reached a ceiling, the next breakthrough may not come from another framework layered on top of the old assumptions.
It may begin by questioning the assumptions themselves.
