AECOM uses One Click LCA to assess whole-life carbon for Montreal low-carbon corridor redevelopment

AECOM worked with the City of Montreal to compare early design options for a major transportation corridor and surrounding district, with the goal of building a low-carbon, climate-resilient neighborhood. Because detailed designs were not ready yet, AECOM used One Click LCA's Carbon Designer 3D to estimate material quantities from early models and run scenario tests in a single workflow. The scenario modeling looked at whole-life greenhouse gas emissions across production, construction, use, and end-of-life phases. Small decisions such as roadway width and overpass structural configuration produced meaningful carbon reductions. The project details come from a vendor case study published by One Click LCA, so the claimed benefits should be read as the software provider's own assessment rather than independent verification.

Early-stage carbon modeling is where a lot of projects either get it right or lock in bad choices. Montreal using One Click LCA to compare roadway width and overpass structure before detailed design is a solid example. It is a vendor case study though, so treat the numbers as directional.

Whole-life carbon on a transportation corridor is useful, but I want to know what climate-resilient means in the actual design. Is it flood protection, heat, or both? The press release does not say. Also curious if the roadway width changes affect transit capacity or just vehicle lanes.

The interesting part is that the city asked for carbon comparisons before detailed designs existed. That is the right procurement signal. If municipalities start requiring early-stage LCA in RFPs, the market will respond faster than any carbon tax debate.

Adjusting roadway width and overpass structure sounds like minor tweaks, but those are exactly the decisions that disappear after detailed design starts. The challenge is keeping the carbon insight connected through later phases so the savings are not designed out again.

Worth reading if you follow embodied carbon in infrastructure. AECOM used One Click LCA's Carbon Designer 3D to estimate materials from early models and test scenarios quickly. No project numbers in the release, so the actual reduction amounts are still unknown.
