Laing O'Rourke Canada office - 1031 Saint-Denis Street, Montreal, Quebec · Transition modelFACILITY

As a regional office asset, this site's dominant dependency is grid electricity rather than water or physical infrastructure; observed grid intensity for Canada (Ember 2025) sits at 190.61 gCO2/kWh, driving the facility's Scope 2 GHG footprint. Water risk is low across the board: baseline water stress is Low (<10%, score 0), overall water risk is Low (0.44/25%), and water depletion is negligible (0.0245). The site draws on the Saint Lawrence (Saint-Laurent) watershed, with riverine flood score of 2.14 (moderate) and a drought score just above 1.0, both unremarkable for an office asset with no process water dependency.

By 2030, the IEA WEO 2024 STEPS pathway projects Canadian grid carbon intensity falling to 75 gCO2/kWh from today's 190.61 — a greater than 60% reduction that will materially lower the facility's Scope 2 emissions with no operational change required. Water-related forward-looking scores (2030 water depletion/stress labels) are not populated in this dataset, so no shift in physical water risk can be evidenced for this horizon; current Low ratings should be treated as the working assumption pending data.

The decarbonisation trajectory continues to 2050, with grid intensity forecast at just 30 gCO2/kWh under STEPS — effectively near-zero-carbon grid supply for this office by mid-century, sharply reducing Scope 2 exposure. No 2080 grid or water horizon data is available, and residual physical risk (flood, drought, water stress) has no projected trajectory in this dataset, so the long-term physical risk picture rests on today's Low baseline scores rather than a modelled forward view.
