GSK's Nairobi manufacturing site draws on an already low-carbon Kenyan grid but carries elevated composite water risk driven by drought and untreated wastewater exposure rather than baseline scarcity.

Today

This is a manufacturing facility flagged internally as a high water-risk site, and the data supports that framing: baseline water stress is Low (BWS score 0.90, <10%), but the overall composite water risk score of 3.13 lands in the High (60-75%) band, driven primarily by a high untreated wastewater score (3.97) and elevated drought score (2.94) rather than scarcity itself. Riverine flood risk is modest (1.20) and coastal flood risk is zero, consistent with the site's inland Nairobi location in the Indian Ocean (ex 160) watershed. On the atmosphere side, the site draws on Kenya's national grid, which in 2025 carried a carbon intensity of just 95.44 gCO2/kWh (Ember Yearly Electricity 2025), a notably clean baseline that keeps Scope 2 emissions impact comparatively low versus peer sites on higher-carbon grids.

Near-term · 2030

No 2030 horizon values are populated for water depletion, water stress, or grid carbon intensity at this site, so forward quantification is not possible from the current dataset; the near-term picture must be read from present-state scores. What is known to persist into the near term is the structural condition driving the High overall risk score, untreated wastewater and drought exposure, since these are infrastructure and climate-pattern issues that do not shift quickly absent capital investment or regulatory intervention.

Long-term · 2050+

No 2050/2080 water-stress, depletion, or grid-intensity projections are populated in this dataset, so the long-term decarbonisation trajectory and residual physical risk cannot be quantified from available horizons. Directionally, Kenya's grid already sits far below global carbon intensity benchmarks, suggesting continued low embodied-carbon exposure for Scope 2 as national generation mix evolves, but the site's water-related trajectory (drought, wastewater infrastructure) depends on local municipal and catchment investment that is not captured here and should be tracked qualitatively.

Call-outs
RISK
Untreated wastewater exposure
The untreated-wastewater score of 3.97 (near the top of a 0-5 scale) signals significant discharge treatment gaps that could drive regulatory or reputational risk in the Indian Ocean (ex 160) watershed.
WATCH
Overall water risk elevated
Despite low baseline water stress (BWS 0.90, Low <10%), the composite overall water risk score of 3.13 sits in the High (60-75%) band, indicating drought and wastewater factors outweigh scarcity in the current risk profile.
OPPORTUNITY
Already low-carbon grid
Kenya's grid carbon intensity of 95.44 gCO2/kWh (2025, Ember) is well below global averages, meaning Scope 2 electricity impact at this site is structurally low and a competitive advantage versus GSK facilities on higher-carbon grids.
WATCH
No forward horizon data
2030/2050/2080 water stress, depletion, and grid-intensity horizon projections are all null, leaving the site's future trajectory unquantified and reliant on qualitative monitoring.
