From tipping points to turning points

We talk about tipping points as if they arrive on their own. But nothing turns without a decision.

At TRANSFORM 2026, Nature Positive Initiative Convenor Marco Lambertini spoke about the choice between “irreversible tipping points” and “exciting turning points”.

This is an important distinction. A tipping point is the moment just before a system crosses a threshold and change becomes irreversible. A turning point is what happens when we decide to act.

The built environment is under pressure right now. Cost constraints, delivery challenges and an unpredictable global context are shaping business decisions. The climate crisis is accelerating – and the conditions around it have become more complex.

What happens next is not inevitable.

At TRANSFORM 2026, we launched a series of papers, projects and partnerships with the potential to shift systems:

• Nature Positive Roadmap – helping new developments to halt and reverse biodiversity loss by 2030, and restore ecosystems by 2050
• Green Star Fitouts – breaking the five-to-seven-year strip-out cycle by prioritising reuse and disassembly
• Keys to Change – showing how scaling Green Star-certified Build-to-Rent to 10% of the apartment market can avoid around 150 million kilograms of carbon emissions each year, while delivering healthier, higher-quality homes for 450,000 Australians
• Data Centres Australia partnership – exploring what best practice sustainability looks like for one of the built environment’s fastest-growing and most energy-intensive asset classes.

None of these are outcomes in themselves. Whether they transform tipping points into turning points is up to us.

Nowhere is this more visible than in the National Construction Code. This is where the abstract idea hits concrete.

The NCC sits at the centre of multiple pressures: housing affordability, construction productivity and climate performance. The decisions made today will shape how comfortable, safe and affordable our buildings are for decades to come.

For a code to be national, consistency across jurisdictions matters. Misalignment creates uncertainty, adds cost and slows progress. The result is buildings that are more expensive to run and less resilient to future conditions.

The alternative is not complexity, but clarity. Alignment gives industry the confidence to invest, to scale and to deliver better outcomes. The GBCA has been clear about this.

Tipping points will determine our future. So will the decisions we make today. These decisions will shape what we build, and how we live with it.
