In an era characterized by major demographic, social, energy and climate challenges, sustainable construction is not just a trend but more of an urgent need. As the construction sector faces the task of accelerating its transformation to address enormous challenges, the Sustainable Construction Barometer 2025, a global survey published by Saint-Gobain’s Sustainable Construction Observatory, offers critical insights that require immediate action across the entire construction value chain.
According to a report by Eri Driva on economix.gr, the Barometer conducted a survey with the participation of stakeholders such as professionals, students, associations, local elected officials and government representatives, in 27 countries and, for the first time this year, included the general public. Through the research, an interesting picture emerged of where we are in our effort for a more sustainable built environment. The findings not only highlight the progress that has been made in raising awareness as a vital foundation for progress, but also reveal the significant gaps that remain, creating an urgent call for collective action, as the World Economic Forum points out.
1. Awareness and urgency are growing
Awareness of sustainable construction is steadily increasing. Notably, 67% of stakeholders report familiarity with the concept, up 6 points from last year, while elected officials show an impressive 32-point jump. The sense of urgency is strong, with 69% of stakeholders considering sustainable construction a priority, as do 60% of the public, while 95% consider it at least important. However, there are some regional differences – for example, in the US, where 34% of the public is still unaware of the concept of sustainable construction. However, to make progress it is necessary to ensure that no region is left behind.

2. Broad consensus, different priorities
The desire to expand the boundaries of sustainable construction is widespread, with 87% of respondents agreeing that “we need to do more” in this area. But who should lead this change? According to the Barometer, private entities are considered the most legitimate drivers, with architects and engineering companies at the forefront (56%) and private companies in the construction sector (44%). Regional priorities, however, differ. In Asia-Pacific, Africa and the Middle East, adapting buildings to natural and climate hazards is paramount, while in Latin America, the use of ecological materials is a priority. Europe is focused on renovating existing buildings and North America is struggling with affordability. This diversity highlights the need for strategies that are globally aligned but locally tailored. While Europe has historically been a leader in sustainable construction, small signs of waning enthusiasm should not go unnoticed. Although the overall desire for more action remains very strong (86% in Europe versus 87% globally), a higher proportion of the remaining minority of respondents in Europe believe that we should “go back”, while elsewhere, most prefer the status quo (“it’s fine the way it is”). Although marginal, this is surprising given the momentum sparked by the Chaillot Declaration a year ago, which rallied support for sustainable building practices. This could reflect frustration with ever-changing regulations in some areas, or perhaps a broader backlash against environmental issues.
3. From environmental focus to resilience and well-being
While sustainability has historically been defined in narrow terms, often focusing exclusively on the environment, the resilience of buildings to climate events is emerging as a key issue. The Barometer reveals that 21% of respondents now report resilience, with this number rising particularly in Africa and Asia-Pacific. This shift reflects the growing urgency of adapting to climate change, particularly in regions that are more vulnerable to extreme weather events. However, the human dimension of sustainable construction remains neglected. Only 15% of stakeholders and public respondents link it to improving the well-being of users. To address past challenges and re-engage marginalized stakeholders who believe we need to move backwards, highlighting the health and well-being benefits of sustainable construction could make a difference. A clearer understanding of its critical role in human comfort and health should contribute to wider adoption.
4. Linking awareness and action through training
Awareness is growing, but action is lagging. While 67% of professionals claim to assess the carbon footprint of their projects, only 30% do so systematically. And while 51% of elected officials want to exclude construction contracts that do not consider sustainable construction methods, only 37% have taken action (despite a 26-point increase since 2024). This disconnect between ambition and action is a significant obstacle to progress and deserves more attention. Lack of training may be one reason. Only 28% of stakeholders feel they fully understand what sustainable construction entails, with professionals and students following elected officials and associations. Indeed, only 35% of professionals have received specialized training and only 28% of students receive regular training. Closing this educational gap could be key to turning awareness into action.
The way forward
The message is clear: the transformation of the built environment is urgent and we are at a critical juncture. Stakeholders across the construction value chain must come together to drive concrete actions towards a sustainable future. The Sustainable Construction Barometer 2025 is a call to action for all of us. The sector has made significant strides forward, but much work remains. It is time to turn awareness into action. Mobilizing all stakeholders – from planning to execution – is essential to creating a resilient, sustainable and livable built environment for future generations.
