2.6.2 IPCC emissions<br />
The CO2 factors used are in accordance with the list of energy carriers used in the Netherlands and<br />
the standard CO2 emission factors [ref 87: Vreuls, 2004].<br />
2.7 Substance profiles<br />
The VOC and PAH profiles have been established by (tables 2.7A through 2.7C) [ref 55: VROM, 1993].<br />
Table 2.8 gives the share of PM2,5 in the PM10-emissions.<br />
2.8 Regionalization<br />
The sections of inland waterways and their lengths originate from the NWB (section on main<br />
waterways). This database is maintained by the Transport Research Centre. Statistics Netherlands<br />
(via StatLine) provi<strong>de</strong>s the data for the number and type of inland waterway vessels and also for the<br />
numbers of recreational boats (motorboats and sailboats). The data on the numbers of mooring places<br />
in yacht harbours originate from the Kennis- en Informatiecentrum Recreatie 19 (KIR).<br />

The uncertainties in emission estimates have been <strong>de</strong>rived from the uncertainty in activity data and<br />
emission factors in accordance with the rule that the uncertainty of the product of two uncertain factors<br />
is equal to the greatest uncertainty of one of the two factors, therefore:<br />
- A * A = A<br />
- A * B = B<br />
- B * A = B<br />
- C * C = C<br />
- A * D = D<br />
etc.<br />
