Sammendrag
The Norwegian emission inventory is a joint undertaking between the Norwegian
Pollution Control Authority and Statistics Norway. The Norwegian Pollution
Control Authority is responsible for the emission factors and for providing data
from specific industries and sources, while emission figures are derived from
models operated by Statistics Norway. Statistics Norway is responsible for
developing the emission models, for the collection and development of activity
data, and for the calculations. Emission data are used for a range of national
applications and for international reporting.
This report documents the methodologies used in the Norwegian emission
inventory of greenhouse gases (GHG), acidifying pollutants, heavy metals (HM)
and persistent organic pollutants (POPs). The documentation will also serve as a
part of the National Inventory Report submitted by Norway to the United Nations
Framework Convention on Climate Change (UNFCCC), and as documentation of
the reported emissions to UNECE for the pollutants restricted by CLRTAP
(Convention on Long-Range Transboundary Air Pollution).
This report replaces the previous documentations of the emission model, Rypdal
(1993), Rypdal (1995b), Flugsrud et al. (2000), Hoem (2005), Hoem (2006) and
Aasestad (2007). The most important changes since last year is a revised method
for calculation of CH4 and N2O emissions from ferroalloy production, revised N2O
figures from one chemical plant for most years since 1990, increased emission
figures for CH4 for all years since 1990 due to corrections of Statistics Norway’s
waste statistics and inclusion of N2O emissions from human sewage from the part
of the population that is not connected to wastewater treatment plants. In addition
there have been several minor changes in the figures, e.g., some figures reported
from plants to the Norwegian Pollution Control Authority have replaced earlier
reported figures. Chapter 8 Recalculation is updated.
