Call for faster action on sustainable construction

The construction sector is making progress on sustainability but still needs to accelerate action, according to Saint-Gobain’s Sustainable Construction Barometer 2025.

The global study, published this month, draws on insights from 4,000 construction professionals and 27,000 citizens across 27 countries, including the UK. It found that 67% of industry stakeholders now claim a good understanding of sustainable construction — an increase of six points compared to 2024 — and 69% believe it should be a top priority.

However, the report warns that the awareness is not yet matched by widespread action. Only 28% of professionals feel fully informed about sustainable construction practices, and just 35% have received specific training. Many stakeholders recognise the importance of low-carbon and resilient buildings but lack the tools, data, or mandates to consistently implement these approaches.

Regional differences are also evident. In Europe, including the UK, renovation of existing buildings is the top priority, reflecting policies aimed at reducing operational carbon emissions. In Asia-Pacific and Africa, the focus is shifting towards building resilience against climate change impacts such as extreme weather.

Saint-Gobain’s research highlights that sustainable construction is still most commonly associated with energy efficiency and the use of eco-materials, but the industry is beginning to place greater emphasis on resilience, circularity, and life-cycle assessments. Environmental performance remains a strong driver, but concerns about social impacts and affordability are gaining ground.

Collective action and collaboration across the construction value chain are seen as essential to progress, along with stronger leadership from private sector players. Architects and engineers are viewed as particularly influential in accelerating change.

In the Benelux region, the report found an advanced focus on circular construction and life-cycle carbon analysis, although administrative burdens linked to sustainability certifications were identified as a challenge.

Saint-Gobain, which launched its Sustainable Construction Observatory in 2023, says the findings underline the need for better data, more training, and practical support to help construction professionals embed sustainable practices at every stage of a project.
