Emission Factors for Road Transport 

These versions have been superseded by the more recent versions on Emission factors for transport. The factors within them may not be directly comparable with more recent versions due to changes in the methods and raw emission factors used to derive them. Previous versions of the NOx and PM speed-related emission functions from earlier versions of COPERT 5, also COPERT 4v10 and COPERT 4 v8.1 and the Base 2019r, Base 2013 and Base 2011 fleet composition projections are archived here. These were used in previous versions of the Emission Factor Toolkit EFT v10, v8, v6.0 and v5.2.
