Non-road fuel consumption and pollutant emissions FOEN 2008 12
Development of non-road emissions from 1980 to 2020
The chronological development of overall non-road emissions is depicted in Figure 2.
Here we can see that emission levels of almost all pollutants considered in this report
increased until 1995. Then from 2002, i.e. when the first EU regulations governing
maximum emission levels entered into effect, emission levels of all pollutants (except
carbon dioxide) began to decrease significantly. The sharpest decline concerns particulate
matter, which is expected to fall to around 20% of the present-day level by 2020.
This is attributable to the introduction of low-emission engines as well as to the assumed
market penetration of particle filters.
Fig. 2 > Relative development of non-road pollutant emissions versus the levels recorded in 2005
The reference year for the development of pollutant emissions is 2005. The trend in emissions of
particulate matter (PM) is based on the development of the inventory of machines retrofitted
with a particle filter (in accordance with Fig. 20).
