Electricity Carbon Calculator — UK
Convert kWh into CO₂e on the UK grid factor, with solar netting and tree-equivalents.
The UK grid fell from 0.5 to ~0.21 kg/kWh in a decade as coal exited — your historical-year comparisons must use year-matched factors. Enter monthly kWh (and any solar offset) for an instant Scope 2 figure with the assumptions visible.
Scope 2 = kWh × combined-margin grid factor. UK's factor of 0.21 kg/kWh reflects its generation mix — coal-heavy grids run 0.6–0.8, hydro/nuclear grids under 0.1. The cheapest decarbonization for most businesses is attacking this line: efficiency first, then on-site solar.
Screening-level estimate using published average emission factors. Audited disclosures (BRSR, GRI, CDP) require primary activity data and verified factors — confirm with your sustainability auditor.

Frequently asked questions
How much CO₂ does electricity produce per kWh?+
Depends on the grid: India ~0.716 kg/kWh (CEA), USA ~0.38, UK ~0.21, France ~0.06, global average ~0.48. The factor is the carbon recipe of the generation mix — this tool applies your region's published value and shows it openly.
Does rooftop solar really zero out my electricity emissions?+
Each solar kWh you consume displaces a grid kWh at the full grid factor — on India's grid, a 3 kW system avoids roughly 3 tonnes CO₂e yearly. The netting field shows it; market-based accounting also accepts green-tariff purchases and RECs with documentation.
Will my electricity footprint shrink automatically over time?+
Yes — grids decarbonize: the UK factor halved in a decade, India's is projected to fall steadily with renewable build-out. The sensitivity row shows your footprint at a halved factor. Efficiency still pays twice meanwhile: every kWh saved is rupees AND carbon today.
Location-based vs market-based — which does the Electricity Carbon Calculator — UK compute?+
Location-based (regional grid average) — the universal default and the comparable number. If you buy green power contractually (green tariff, RECs, PPAs), market-based accounting may report lower; serious disclosures show both, per GHG Protocol Scope 2 guidance.
