The Other Waste category includes compost production, accidental building-
and vehicle fires
Composting includes four types of biological waste; garden and park waste,
organic waste from households and other sources, sludge and home composting
of garden and vegetable food waste. Individual emission factors are
found for each waste category.
Emissions from building fires are calculated by multiplying the number of
building fires with selected emission factors. Six types of buildings are separated
with different emission factors; detached houses, undetached houses,
apartment buildings, industrial buildings, additional buildings and containers.
Activity data for building fires are classified in four categories; full scale,
large, medium and small. The emission factors comply for full scale building
fires and the activity data is therefore recalculated as a full scale equivalent
where it is assumed that a large, medium and small fire leads to 75 %, 30 %
and 5 % of a full scale fire respectively.
Emissions from vehicle fires are calculated by multiplying the total burnt vehicle
mass with selected emission factors. 14 different vehicle types are included
in the total mass of burned vehicle. Emission factors are not available
for different vehicle types, why it is assumed that all the different vehicle
types lead to similar emissions. As with accidental building fires, four different
sizes are known in relation to damage; full scale (100 % burnout), large
(75 %), medium (30 %) and small (5 %).
Please refer to Chapter 7 and Annex 2D for further information on emission
inventories for agriculture.

The determination of key categories has not been made due to insufficient
resources being available at the moment.

In the Danish National Inventory Report to UNFCCC (Nielsen et al., 2011),
the plan for Quality Control (QC) and Quality Assurance (QA) for greenhouse
gas emission inventories prepared by the Danish National Environmental
Research Institute is outlined. The plan is in accordance with the
guidelines provided by the UNFCCC (IPCC, 1997) and the “Good Practice
Guidance and Uncertainty Management in National Greenhouse Gas Inventories”
(IPCC, 2000). The ISO 9000 standards are also used as important input
for the plan. The plan also, to a limited extent, includes the gases reported
to the UNECE-LRTAP Convention. Due to a lack of resources it has
not been possible to extend the QA/QC system for the greenhouse gas inventory
to also cover the air pollutants.
