HELSINKI (Finland), December 17, 2024 — With greenhouse gas in the atmosphere surging to the highest levels ever recorded, carbon reduction efforts must accelerate. According to the WGBC, buildings are responsible for 39% of global energy-related carbon emissions. The world leader in construction and infrastructure LCA and EPD data, One Click LCA, provides topical data that shows where global construction can concentrate efforts to reduce emissions and improve sustainability.
One Click LCA’s data shows that the carbon reduction potential in construction projects is higher when sustainability is considered from the start. One 2024 hallmark case by One Click LCA, in collaboration with industry giant AECOM, shows that emissions can be reduced by as much as 50% when decisions are made early in the design phase—when targets are set, major design decisions are made, subcontractor guidelines are defined, and the overall plan for the building and construction process is set.
If the lowest carbon-emitting products are selected for all materials in a building, carbon emissions can be reduced by more than one-third. The calculations are based on One Click LCA’s database of LCA data and EPDs for +250,000 global construction products. The impact is particularly high when choosing lower-carbon emitting products for concrete and steel needs, as thermally manufactured, carbon-intensive structural materials make up a large portion of materials used in projects.
In addition, building services (MEP) represent a significant proportion of embodied carbon, according to CIBSE. In the case of a new build, building services account for 15-50%, depending on the impact scenario. In the case of a refurbishment or retrofit, building services account for 40-70% of embodied carbon emissions. MEP sector product data, however, is increasing, with leading manufacturers like Schneider Electric making transparency in MEP a sustainability priority.
A 2024 One Click LCA study showed frustration in the industry with the lack of progress in national and international sustainability regulations, but also with the lack of EPD data available when critical project decisions are made. 87% of construction professionals surveyed see the lack of manufacturer EPDs as the primary obstacle to LCA and embodied carbon advancement. At the same time, 83% of construction professionals surveyed indicate that a lack of national regulation and policies is a barrier to LCA adoption.
“Having the ability to compare low- and high-carbon alternatives will benefit the entire construction sector to make informed decisions. We must increase cooperation within the industry to drive sustainable development across the full construction value chain — and help the global construction industry ecosystem to tackle sustainability challenges on the road to net zero.”

Used in 170+ countries, One Click LCA is the leading end-to-end sustainability platform for construction and manufacturing. The AI-powered software decarbonizes and drives sustainability across the construction value chain with scientific, easy-to-use, automated life-cycle assessment (LCA) and environmental product declarations (EPDs) to calculate and reduce the environmental impacts of building, infrastructure, and renovation projects and products. The platform also allows assessment of circularity, life-cycle cost, and biodiversity. One Click LCA is used by blue-chip enterprises like Skanska, WSP, Foster+Partners, LafargeHolcim, ArcelorMittal, Arcadis, AECOM, Geberit, and Saint-Gobain, among others. It offers a unique global database with +250,000 LCA datasets; supports +80 standards and certifications, including LEED, BREEAM, GRESB, and other national regulations; and seamlessly integrates with +20 of the most widely used BIM software tools, including Autodesk Revit®, Tekla Structures® and Bentley iTwin®. One Click LCA was founded in Helsinki, Finland, in 2001, with a team of +200 people on all continents. Learn more at: oneclicklca.com
