Karachi West Wharf · Transition modelFACILITY

Karachi West Wharf is classified as a manufacturing site with an explicit "high water risk" designation, sitting in the Arabian Sea (ex 253) watershed under Extremely High baseline water stress (BWS score 5, >80%) and an overall local risk score of 3.6 (High, 60-75%). Untreated wastewater risk is elevated at 3.97, while riverine flood score sits at a moderate 2.5 and coastal flood risk is negligible (0.018). On the impact side, Scope 2 emissions exposure tracks Pakistan's grid, currently at 480 gCO2/kWh (2023 Ember observed) — among the higher-carbon grids GSK operates against — making water stress and grid carbon intensity the two dominant present-state pressures at this site.

By 2030, Pakistan's grid carbon intensity is projected to drop from the 2023 observed 480 gCO2/kWh to 350 gCO2/kWh (IEA WEO 2024 STEPS), a meaningful Scope 2 tailwind for this manufacturing asset. Water-side, however, no 2030 depletion or stress horizon scores are populated, so GSK has no forward signal on whether the current Extremely High (BWS 5, >80%) baseline stress and 3.6 overall risk score (High, 60-75%) will shift; the site should be treated as static-high-risk for planning purposes absent new data.

The grid trajectory continues favorably to 215 gCO2/kWh by 2050 under STEPS, meaning Scope 2 intensity at this facility could fall by more than half from today's 480 gCO2/kWh baseline over the next 25 years, a structural decarbonisation tailwind largely independent of site-level action. Physical water risk is the unresolved variable: with no 2050 or 2080 water stress/depletion horizon labels or scores available, GSK carries residual uncertainty on whether Karachi's already-extreme water stress deepens, and the site's "high water risk" asset subtype classification suggests this gap needs closing before long-range capital or resilience decisions are made."
