🤔How do we measure circularity?
Circle Economy measures the 'circularity' of a city, country, region or the globe by looking at the proportion of secondary materials it uses.
We calculate this by dividing secondary material use by total material use (virgin + secondary).
Both components are essential: we can boost circularity by increasing secondary material use (using again) and by decreasing total material use (using less).
Our Circularity Metric considers ‘secondary materials’ to be those that were formerly waste, but are now being used again.
According to this methodology, the global economy today is 7.2% circular.

Sustainable construction is moving from ambition to delivery as policy, procurement and building performance converge around whole life carbon, embodied carbon and life cycle cost.
Record uptake of Boiler Upgrade Scheme vouchers in Britain indicates that heat pumps are entering the mainstream for housing, retrofit and low carbon building specification. Germany’s 2045 phase-out of oil, gas and coal reinforces the direction for net zero carbon buildings across Europe: electrification, energy-efficient buildings and low carbon design are becoming market requirements, not optional sustainability claims.
The industry’s capacity to deliver remains the decisive constraint. Calls for stronger construction training and reskilling underline a core risk for environmental sustainability in construction: policy can drive demand, but competent labour determines whether sustainable building design performs in practice. The post-Building Safety Act regime raises the bar for building control, fire-safety competence and verifiable compliance.
Net zero whole life carbon ambitions depend on robust whole life carbon assessment, lifecycle assessment, sustainable material specification and evidence such as environmental product declarations (EPDs), not on poorly installed systems or untested green building products.
Circular economy in construction is shifting into practical specification. New guidance on reusing doors shows how embodied carbon in materials can be reduced through repeatable procurement, inspection, warranties and end-of-life reuse in construction. The next phase of green construction will rely on circular construction strategies, resource efficiency in construction, low embodied carbon materials and low carbon construction materials as much as new technology. Standards including BREEAM and BREEAM v7 will sharpen expectations for building lifecycle performance, carbon footprint reduction and credible eco-design for buildings. The sector’s credibility now rests on proving that sustainable building practices, eco-friendly construction and carbon neutral construction can withstand the scrutiny of installers, inspectors, clients and quantity surveyors.
