This information is not available. Total greenhouse gas emissions for each mode of transport are published in Transport Statistics Great Britain table ENV0201: https://www.gov.uk/government/statistical-data-sets/energy-and-environment-data-tables-env. Total emissions for each transport mode are calculated using various methodologies and data sources. Due to the differences in data sources and calculation methods, it is currently not possible to disaggregate total emissions in a way that allows the calculation of comparable average passenger emissions for the different transport modes. The Department for Business, Energy and Industrial Strategy does produce conversion factors for use in company reporting, covering a full range of activities which produce greenhouse gas emissions, although these figures are not statistically evidential.
