Emission Factor Datasets

Emission factors for burning fuels — natural gas, diesel, coal, biomass and the rest — plus the calorific values and upstream well-to-tank factors that go with them. The starting point for most Scope 1 inventories.

Grid carbon intensity by country and region, the transmission and distribution losses that sit on top of it, and cloud-region intensities. What Scope 2 reporting is built from.

Average home electricity price in every US state each month since 2010 (EIA). Tap a state on the map for its page, or open the all-state comparison.

Per-kilometre and per-tonne-kilometre factors for business travel, freight and delivery across air, road, rail and sea.

Emission intensity per unit of spend, by industry sector. Used when you know what you paid but not what you bought — the basis of most Scope 3 Category 1 screening.

Embodied carbon for construction products across their life-cycle modules, and measured energy benchmarks for existing dwellings.

Treatment and disposal factors by waste stream and route — landfill, recycling, composting and incineration.

Process emissions that come from chemistry rather than fuel: cement calcination, aluminium smelting, ammonia and the other IPPU sources.

Agriculture, forestry and other land use — livestock, soils, rice, manure, biomass burning, land-use change and wetlands, at IPCC Tier 1 defaults.

The global warming potentials used to convert each gas to CO₂e, including the full refrigerant and F-gas list.
