Construction’s sustainability reporting revolution
The built environment is responsible for two-fifths of global carbon emissions. In the UK alone, construction generates three-fifths of all waste. These figures have been known for years, yet the industry’s response has been decidedly skewed. We have collectively poured enormous effort into reducing operational carbon through better insulation, improved thermal efficiency, modern heating systems and renewable energy. But upfront embodied carbon, the emissions locked into our materials – from their extraction, manufacture, storage and transportation through to installation – has largely escaped scrutiny.
Fortunately, this imbalance is starting to correct itself, and the numbers tell a compelling story. According to the NBS Digital Construction Report 2025, three in five construction professionals now use digital technology to measure upfront embodied carbon, up from two in five in 2023. Over half the industry has adopted digital tools for lifecycle analysis, a sharp rise from one-third just two years ago. These are significant gains, representing a fundamental shift in how the sector approaches environmental accountability.
The timing matters. Carbon reporting in construction projects is earmarked as one of the sector enablers in the UK Government’s Carbon Budget and Growth Delivery Plan (‘The Plan’). The Plan sets out how the UK will achieve net zero over the coming years and whole-life carbon assessments for buildings are noted as one of these enablers against Carbon Budget 5, from 2028 onwards. Professionals who master these measurement techniques now will find themselves well-positioned for anticipated regulatory change. Those who delay risk rushing to meet requirements they don’t yet understand with tools they haven’t learned to use.
But this shift is about more than regulatory compliance. Upfront embodied carbon often represents the largest slice of a building’s environmental impact, particularly for low-energy structures where operational emissions have already been minimised. For a typical UK office operating over 60 years, upfront embodied carbon comprises 35% of its whole-life carbon. For energy-efficient buildings, as operational emissions decline, this proportion can reach 75%. Unlike operational carbon, upfront embodied carbon emissions are locked in at construction and cannot be reduced afterwards. For architects and specifiers, understanding this upfront impact is essential to making genuinely sustainable design decisions.
Digital technologies are transforming how we track and manage this carbon. The ability to provide accurate, real-time environmental data throughout a project’s lifecycle is increasingly valued by professionals, investors and regulators. These tools enable transparency whilst providing insights to optimise environmental performance during design and construction.
The acceleration is striking. Of the architecture professionals surveyed in NBS’ 2025 study, three in five agree that digital technologies are having a positive environmental impact. (A significant increase over the previous survey’s findings.) Just one in seven professionals are not using digital technologies for environmental assessments. Conclusion? The industry looks to have reached a tipping point.
For the first time, half of respondents to NBS research believe the construction sector is no longer lagging behind other industries in digital adoption, compared to just one quarter in 2023. This growing confidence reflects a maturing understanding that responsible sustainability reporting and upfront embodied carbon tracking represents a design advantage, not an administrative burden.
Upfront embodied carbon is the foundation for responsible whole-life carbon reporting. Addressing “hidden” carbon unlocks a more complete picture of a building’s environmental credentials, not to mention the potential for cost reductions during the operational lifespan of a building. Besides the direct correlation between reducing energy demand and costs, the selection of products and materials for longevity and reduced service intervals can also demonstrate gains. This typically aligns with the age-old saying of, “what gets measured gets done”. Clients may easily look past whole-life costs if they are not presented clearly, and a shift to whole-life carbon reporting, including upfront embodied carbon, can help address that.
The construction industry faces legitimate criticism for its environmental impact. But the data suggests we are moving beyond aspiration and into daily practice. Three-fifths of professionals now use digital tools for energy and water assessment. The systems, the will, and the understanding are all aligning.
The question for forward-thinking practices is not whether to engage with embodied carbon measurement, but how quickly to build this capability into standard workflows. Those who view carbon data as a strategic asset will find themselves with a competitive advantage in a marketplace that increasingly demands environmental transparency. The revolution in sustainability reporting is well underway. Embodied carbon is finally getting the attention it deserves.
