How do you cut embodied carbon before a design is even finished?

AECOM used One Click LCA's Carbon Designer 3D to run a whole life carbon assessment for a major redevelopment project for the City of Montréal, before detailed designs or material data existed. Using basic building dimensions, the analysis identified carbon hotspots and showed which decisions, like roadway width and overpass configuration, mattered most for emissions. — How do you cut embodied carbon before a design is even finished? AECOM used One Click LCA's Carbon Designer 3D to run a whole life carbon assessment for a major redevelopment project for the City of Montréal, before detailed designs or material data existed.

Early design insights from One Click LCA helped AECOM show lower-carbon options before detailed plans were ready.

MONTREAL, Sept. 22, 2026 /PRNewswire/ -- The City of Montréal launched a project to redevelop a major transportation corridor and surrounding district with a clear vision: create a low carbon, climate-resilient neighborhood. The City needed to compare early design concepts before detailed designs were available. AECOM was tasked with providing whole-life carbon insights to support climate-aligned decisions, and used One Click LCA's Carbon Designer 3D to estimate material quantities from early models, rapidly test scenarios, and assess impact in one streamlined workflow.

"One Click LCA played a pivotal role in this project by providing actionable insights early in the design process. Using Carbon Designer 3D alongside other tools, we modeled life cycle greenhouse gas emissions for major components across the production, construction, use, and end-of-life phases."
-Jérémy Lagneau, ESG and Decarbonization Advisor, AECOM

When the project was in the pre-design phase, AECOM integrated One Click LCA directly into its ScopeX™ decarbonization workflow. Scenario modeling showed that subtle design decisions, like adjusting roadway width or optimizing overpass structural configuration, yielded meaningful carbon reductions.
