US heavy duty transport IPCC

This category contains data associated with heavy duty truck transport in the US, sourced from the IPCC Guidelines for National Greenhouse Gas Inventories.

The data is organised in to fuel types ('conventional', 'alternative'), with emissions estimates for CO2 and CO2e (i.e. CO2, CH4 and N2O) available.

It should be noted that the US-specific categories are similar to those within the /transport/lgv/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. In addition, the IPCC data and methodology are organised according to vehicular emissions control technology rather than vehicle age (although these are directly related) and include emissions associated with vehicle 'cold starts' as well as distance travelled.
