The dominant dependency at this facility is grid electricity for cooling and IT load, with Scope 2 GHG intensity the primary impact channel — the GB grid currently observed at 217.41 gCO2/kWh (Ember 2025). Physical pressure centers on water: the site falls in a High (40-80%) baseline water stress band (score 3.38) within the North Sea watershed (ex 605, 629, 633, 634, 638), with a drought score of 3.31 signaling meaningful dry-period exposure even though overall composite risk is rated Low (score 0.64) and coastal flood exposure is zero. Riverine flood (1.03) and water depletion (1.30) scores are moderate-low, suggesting water stress here is a baseline-availability concern rather than an acute flood or depletion issue.

By 2030, the IEA WEO 2024 STEPS pathway projects GB grid intensity holding at 100 gCO2/kWh — a marked drop from the 2025 observed 217.41 gCO2/kWh — meaning Scope 2 emissions per unit of energy consumed should nearly halve over this horizon if consumption stays flat. Forward-looking water stress and depletion horizon scores (2030/2050/2080) are not populated in this dataset, so no quantified shift in physical water risk can be cited; the High baseline stress rating today should be treated as the operative planning assumption until horizon data is available.

The grid trajectory continues sharply toward 30 gCO2/kWh by 2050, positioning London IBX's Scope 2 footprint to shrink to a fraction of current levels purely from grid decarbonisation, independent of any on-site efficiency action. Residual physical risk is harder to characterize: with no 2050/2080 water stress or drought labels provided, the facility's long-term exposure to intensifying basin-level water stress in the North Sea watershed remains an open data gap rather than a quantified trend, and should be flagged for follow-up given London's already-High current rating.
