GSK's Stevenage R&D/manufacturing site sits in a High baseline water-stress watershed (North Sea basin) even as the UK grid decarbonises sharply through 2050.

Today

Stevenage's dominant physical exposure today is water: baseline water stress scores High (40-80%, score 3.38) with an elevated drought score of 3.31, though overall composite risk is scored Low (0.64) and coastal/riverine flood exposure is negligible to modest (riverine 1.03, coastal 0). The dominant impact pathway is Scope 2 GHG via grid electricity, currently carrying a GB grid intensity of 217.41 gCO2/kWh (Ember 2025 observed). No flow-level water withdrawal, energy consumption, or asset-value data is populated for this site, limiting quantification of absolute dependency magnitude.

Near-term · 2030

By the 2030 horizon, IEA WEO 2024 STEPS projects GB grid intensity effectively flat to slightly up relative to today's observed trajectory (horizon marker shows 100 gCO2/kWh scaling reference, moving to 30 by 2050 - a step-change reduction), meaning Scope 2 emissions intensity is set to fall materially in the back half of this decade into the 2030s. Water stress and drought future scores for 2030/2050/2080 are not populated in this dataset, so the trajectory of physical water risk at Stevenage cannot be forward-quantified beyond the current High baseline stress reading - this is a data gap analysts should flag rather than assume stability.

Call-outs
RISK
High baseline water stress
Stevenage sits in a High (40-80%) baseline water stress watershed with an elevated drought score of 3.31, a live constraint on any water-intensive R&D/manufacturing processes.
OPPORTUNITY
Grid decarbonisation tailwind
UK grid intensity is projected to fall to roughly 30 gCO2/kWh by 2050 under IEA STEPS, sharply reducing Scope 2 emissions without site-level action.
WATCH
Missing water horizon data
No 2030/2050/2080 water stress or depletion projections are populated, leaving forward physical water risk unquantified for this site.
WATCH
No flow-level metrics
Absence of flows data (water withdrawal, energy use, asset value) constrains precise dependency sizing and scenario stress-testing for Stevenage.
