2. INLAND NAVIGATION
2.1 Introduction
This chapter describes the methods that have been used to ascertain the emissions caused by inland
navigation. This is defined as all motorized vessels that travel on the inland waterways in the
Netherlands. Traffic on the inland waterways comprises, among other things, professional goods
transport, passenger transport and recreational boat traffic.
The emissions caused by inland navigation are part of both the actual emissions and the IPCC and
NEC emissions. In the IPCC emissions, only vessel movements are included for which the point of
departure and the point of arrival both lie within the Netherlands. Various aspects are in accordance
with the IPCC regulations. No IPCC emissions caused by recreational traffic are calculated because
the sales of fuel to the sector are not known. This is because it is difficult to make a distinction
between supplies of motor fuels for road traffic and supplies for recreational boat traffic.
