This update is focused on improving data consistency, increasing collaboration across teams, … Read more

In our previous article, we explored why carbon compliance often fails at the project level, showing how evidence decay, fragmented assumptions, and audit exposure can turn well-intentioned design into downstream risk. When you scale from a single project to dozens of buildings, multiple infrastructure assets, and multi-year programmes, these risks multiply. Inconsistent methodologies, disconnected data, … Read more

Following our discussion on upfront carbon, this article explores how infrastructure projects in Australia and New Zealand can turn sustainability points into credible, auditable, lifecycle-focused evidence – ensuring decisions are aligned across design, delivery, and operation. Imagine an infrastructure project where design teams achieved every sustainability credit in the Sustainability Infrastructure (IS) rating … yet … Read more

In our previous article, we explored why UK projects can no longer rely on a single rating scheme and must instead manage a structured carbon compliance stack. Even organisations that recognise this need face a harder truth: carbon compliance rarely fails at the design stage. It tends to emerge later – during audit, investor due … Read more

For years, Australia and New Zealand have focused on operational carbon, tracking energy use and emissions during building operation. Embodied carbon (upfront emissions) has only recently gained attention, captured in NABERS’ A1–A5 categories for materials and construction. While important, focusing only on operational or upfront carbon misses the full lifecycle footprint, including maintenance, refurbishment, and … Read more

Relying on BREEAM alone is no longer enough. UK projects that assume ticking a design or construction rating as sufficient risk compliance failures, costly rework, delayed approvals, and loss of investor confidence. Today, sustainability compliance requires continuous, auditable management of carbon performance across design, construction, and operation – not just a single milestone. Organisations that … Read more

For years, carbon modelling has been treated as a technical exercise. Something sustainability teams or consultants produce to support design decisions, rating submissions, or ESG reporting. In Australia and New Zealand, that is no longer enough. As NABERS evolves, expectations around carbon performance are tightening. Carbon modelling now shapes real‑world outcomes: planning submissions, commercial credentials, … Read more

The built environment sector accounts for 37% of global greenhouse gas emissions, making decarbonisation critical to achieving net zero by 2050. BREEAM New Construction Version 7, launched in July 2025, represents the most significant update to the world-leading sustainability assessment, with a strong focus on reducing whole life carbon while maintaining excellence in occupant wellbeing … Read more

Message from CEO: Chris de Josselin As we head into the new year, I wanted to share a brief update on what I’m seeing across the industry and what we’ve been focused on at Cerclos. One thing that continues to stand out is how far ahead the UK is when it comes to whole-of-life carbon … Read more
