Emission intensity of supply chain (purchase of service/standard good/capital good) in US dollars spend on: subway travel. Factors retrieved from the Quantis+GHG Protocol Scope 3 Calculator for the year 2016 and apply for years beyond 2016. The same emission factor applies to different types of investments in joint ventures/subsidiaries/associate companies that were not captured in Scope 1 emissions.

Subway

Emission intensity of supply chain (purchase of service/standard good/capital good) in kilometers travelled by: subway. Factors retrieved from the Quantis+GHG Protocol Scope 3 Calculator for the year 2016 and apply for years beyond 2016. The same emission factor applies to different types of investments in joint ventures/subsidiaries/associate companies that were not captured in Scope 1 emissions.

Intercity Rail - Other Routes

Emission intensity for international rail passenger train including fuel consumption. The international rail factor is based on a passenger-km weighted average of the conversion factors for the following Eurostar routes: London-Brussels/London-Paris/London-Marne Le Vallee (Disney)/London-Avignon/London-Amsterdam/London to Bourg-Saint-Maurice (ski train). Retrieved from the Conversion Factors 2021: flat file published by the UK BEIS/Defra at the source URL.

International rail passenger train

Emission intensity of international rail. The primary source is UK DEFRA - Business Travel - land 2019. WARNING: This emission factor has not passed our data validation process as the primary source reports the CH4 and N2O values in kg but the GHG protocol reports them in grams. We have included this for completeness to retain consistency with the source.

International rail

Emission intensity for light rail and tram passenger train including fuel consumption. The light rail factors were based on an average of factors for a range of UK tram and light rail systems. Retrieved from the Conversion Factors 2021: flat file published by the UK BEIS/Defra at the source URL.

Light rail and tram passenger train

Emission intensity of light rail and tram. The primary source is UK DEFRA - Business Travel - land 2019. WARNING: This emission factor has not passed our data validation process as the primary source reports the CH4 and N2O values in kg but the GHG protocol reports them in grams. We have included this for completeness to retain consistency with the source.
