Generic bus transport IPCC

[edit / update model]
This category is deprecated. The IPCC methodologies for European and US bus transport can be found here and here respectively

This category contains data associated with bus-travel in both European and US contexts, sourced from the IPCC Guidelines for National Greenhouse Gas Inventories.

The data is organised in to geographic subcategories ('europe', 'us'), within which vehicular emissions are calcuable according to fuel type and emissions control standards, with emissions estimates for CO2 and CO2e (i.e. CO2, CH4 and N2O) available.

The IPCC methodology for greenhouse gas emissions associated with 'mobile combustion' recommend calculating CO2 emissions on the basis of fuel consumed, whereas those of CH4 and N2O vary more directly with other factors such as vehicle type, emissions control, frequency of cold starts, and distance travelled. Therefore, these categories provide a number of options for calculating bus-associated greenhouse gas emissions, depending on which combination of fuel consumption, fuel efficiency and distance are specified.

It should be noted that the US-specific categories are similar to those within the /transport/bus/generic/ghgp subcategories, in that both are ultimately derived from similar EPA datasets. The main difference is that the IPCC methodology maintains the calculation of CO2 by fuel quantity and CH4 and N2O by distance - as presented in the original EPA dataset. In contrast, the GHG Protocol methodology uses typical mileage data for each vehicle type in order to express emissions for all gases on the basis of distance.
