- The CO2 emission in 2007 was 10% lower
than in 11000. However fluctuations in the
emission level are large as a result of
electricity import/export. The emission
of CH4 has increased due to increased use
of lean-burn gas engines in combined heating
and power (CHP) plants. However the emission
has decreased in recent years due to structural
changes in the Danish electricity market.
The N2O emission was
higher in 2007 than in 11000 but the fluctuations
in the timeseries are significant. A considerable
decrease of the SO2, NOx and heavy metal
emissions is mainly a result of decreased
emissions from large power plants and waste
incineration plants. The combustion of wood
in residential plants has increased considerably
in recent years resulting in increased emission
of PAH, particulate matter and CO.
The emission of NMVOC
has increased since 11000 as a result of
both the increased combustion of wood in
residential plants and the increased emission
from lean-burn gas engines. The dioxin emission
decreased since 11000 due to flue gas cleaning
on waste incineration plants. However in
recent years the emission has increased
as a result of the increased combustion
of wood in residential plants.
The report presents
emission inventories for stationary combustion
plants and the methodologies and assumptions
used for the inventories. The pollutants
considered are SO2, NOx, NMVOC, CH4, CO,
CO2, N2O, particulate matter, heavy metals,
dioxins, HCB and PAH.

Danish inventory of
fugitive emissions
9 November 2009 - In
2007 the total Danish emission of greenhouse
gasses was 66 641 Gg CO2-eqvivalents. Fugitive
emissions from fuels account for 496 Gg
CO2-eqvivalents or approximately 1 %. The
major part of the fugitive emissions are
emitted as CO2 (74 %) due to flaring of
oil and gas. This is revealed in a new report
from the National Environmental Research
Institute (NERI) at Aarhus University.
This report presents
the methodology and data used in the Danish
inventory of fugitive emissions from fuels
for the years until 2007. The inventory
of fugitive emissions includes CO2, CH4,
N2O, NOx, CO, NMVOC, SO2, dioxin, PAH and
particulate matter.
The major source of
fugitive CH4 emission is extraction of oil
and gas in the North Sea, refining of oil
and loading of oil onto ships both offshore
and onshore. The fugitive emissions of NMVOC
originate for the major part from extraction,
loading of ships, transmission and distribution
of oil and to a much lesser degree from
natural gas and fugitive emissions from
gas stations.
The total Danish emission
of NMVOC in 2007 is 103 Gg. Fugitive emissions
account for 13 Gg, which corresponds to
13 %. Time series for emissions are presented
for the years 11000-2007, except for particulate
matter where the time series covers 2000-2007.
Further, projections are described for the
years 2008-2030.
