Ireland emission factors: grid, losses and fuels.
SEAI 2025 provisional · 178.3 g CO2/kWh, gross electricity supply (CO2 only)
Grid electricity
Our carbon reports multiply a company's purchased kWh by this factor for location-based Scope 2. The source publishes CO2 only, with no methane or nitrous oxide, and the report says so.
Network losses are reported separately, in Scope 3 Category 3: Eurostat nrg_cb_e 2024 · Ireland losses 6.9% of electricity delivered.
Fuels
Fuel burned in vehicles and equipment the company owns or controls is Scope 1. When a ledger gives fuel spend and we hold a published local price for that fuel and month, the engine turns the spend into litres or kWh at that price and applies the factor below (see supported countries). Fuel spend without a local price is priced at a US reference price, and fuel quantities entered directly in litres or kWh use the EPA Hub factors.
| Fuel | Factor | Source |
|---|---|---|
| Petrol | 2.311 kg CO2 per litre | SEAI kg CO2/L, CO2 only |
| Diesel | 2.682 kg CO2 per litre | SEAI kg CO2/L, CO2 only |
| Heating oil | 2.682 kg CO2 per litre | SEAI kg CO2/L, CO2 only |
| Natural gas | 0.1835 kg CO2 per kWh | SEAI kg CO2/kWh, CO2 only |
