Didcot Office sits in a High baseline water-stress catchment (BWS 3.39/5) while its Scope 2 footprint tracks a UK grid already mid-decarbonisation and set to steepen sharply by 2030.

Today

As an office asset, Didcot's dominant dependency is grid electricity and its dominant impact is Scope 2 GHG, currently priced against a GB grid intensity of 217.41 gCO2/kWh (2025, Ember). Physical pressure is concentrated on water: the site falls in the North Sea watershed (ex 605, 629, 633, 634, 638) with a High (40-80%) baseline water stress label (score 3.38) and an elevated drought score of 3.31, though overall composite risk is labelled Low (score 0.64) with negligible coastal flood exposure (0) and modest riverine flood exposure (1.03). Water depletion (1.30) and untreated wastewater (0.16) scores are both low, consistent with a non-industrial office footprint with no significant water withdrawal dependency.

Near-term · 2030

By 2030, the GB grid emissions factor is projected at 100 gCO2/kWh under IEA WEO 2024 STEPS — under half today's observed intensity — directly compressing Scope 2 exposure for this office without any operational change required on-site. Water-related forward horizons (2030 WS/WD scores and labels) are not populated in this dataset, so no directional read is available on whether the High baseline stress classification intensifies or eases; this is a data gap analysts should flag rather than assume stability.

Call-outs
OPPORTUNITY
Grid decarbonisation cuts Scope 2
GB grid intensity is set to fall from 217 gCO2/kWh (2025) to 100 by 2030 and 30 by 2050, sharply reducing this office's Scope 2 exposure with no site-level action needed.
WATCH
Missing water horizon data
No 2030/2050/2080 water stress or drought projections are populated for the North Sea watershed, leaving forward physical-risk trajectory unquantified despite a High current baseline stress label.
RISK
High baseline water stress today
The site's watershed carries a High (40-80%) baseline water stress score of 3.38 and drought score of 3.31, elevated relative to its Low overall composite risk rating of 0.64.
WATCH
Low flood exposure confirmed
Coastal flood score is 0 and riverine flood score is a modest 1.03, indicating flood risk is not a material driver at this office location.
