Bus & Train According to DEFRA are Now Available

Bus & Train DEFRA Methodology Live 2024

The DEFRA 2024 methodology for bus and train carbon emissions is now live in the SQUAKE API. It includes:

• Updated emission factors for local buses (London/non-London), coaches, and train services.

• Energy scopes: Supports Tank-to-Wheel (TTW) and Well-to-Wheel (WTW, default) emissions.

• Granular classification: Differentiates transport modes for improved accuracy.

Users can now retrieve DEFRA-compliant emissions data for both buses and trains via the API. For details, see UK Government GHG factors.
