Heavy Goods Defra

[/transport/lgv/generic/defra]

This category is deprecated. The latest DEFRA methodology for heavy goods vehicle transport can be found here.

This category uses the most recent Defra data and advice to calculate emissions from UK heavy goods travel. The most accurate way to measure emissions is by fuel use using the Fuel category. But often this data is not available, or, specifically for freight categories, all emissions are not due to the packages being monitored. Therefore, this category allows the user to estimate their greenhouse gas emissions based on the vehicle distance travelled and the vehicle load mass. This category is used if the vehicle distance and approximate load are known. If the freight distance and mass are known then the Load Mass category should be used.

How to use this category

Use the drill-down type to select the type of Heavy Goods Vehicle used from the following options.

  • rigid
  • articulated
  • unknown
Use the second drill-down size to select the size of vehicle from the following options.

  • 3.5-7.5t - rigid only
  • 7.5-17t - rigid only
  • greater than 17t - rigid only
  • uk average
  • 3.5-33t - articulated only
  • greater than 33t - articulated only
Use the third drill-down percentageLaden to select the load percentage of the vehicle from. The options for this drill down are essentially 0, 50, 100 or average percentage loads.

The vehicle distance must then be entered as profile item values.

Algorithm

CO2eEmissionFactor = CO2EF + N2OEF + CH4EF

kgCO2e = CO2eEmissionFactor * distance

The result is equivalent CO2 emissions, which includes contributions from carbon dioxide, nitrous oxide and methane emissions.
