Background
• National focal point for air emissions• Responsible institute for estimating GHG emissions
under the Kyoto-protocol• Reporting of emission inventories to
– UNFCCC, UNECE/EMEP, EU, EU-directives (LCP, NEC, EPER)
• Participation in international negotiation (EU, COP)• Development of emission models and improvement
of emission estimates
Resources: 6 man year
Participate in research projects

Ressources for NS
Starting point: ”We already have a NS in Denmark we just have to described it”
Reality: A lot of work had to be done

Sources and Pollutans
• Sources– Energy
• Stationary combustion plants
• Transport

Inventory planning
Designate a single national entity with overall responsibility for the national inventoryThe National Environmental Research Institute (NERI) under the Danish Ministry of Environment is responsible for the annual preparation and submission to the UNFCCC (and the EU) of the National Inventory Report and the GHG inventories.
Define and allocate specific responsibilities in the inventory development process•The inventory work in Denmark is carried out in co-operation with other Danish ministries, research institutes, organisations and companies•There is made formal agreement about delivery of data

External data
Energy
Danish Energy Authority, The Ministry of Economic and Business Affairs: Annual energy statistics in a format suitable for the emission inventory work and fuel consumption data for the large combustion plants.
The Road Directorate, The Ministry of Transport. Number of vehicles grouped in categories corresponding to the EU classification, mileage (urban, rural, highway), trip speed (urban, rural, highway).
Civil Aviation Agency of Denmark, The Ministry of Transport. City-pair flight data (aircraft type and origin and destination airports) for all flights leaving major Danish airports.
Danish Railways, The Ministry of Transport. Fuel related emission factors for diesel locomotives.
9
Industrial processes
Danish Environmental Protection Agency, The Ministry of the Environment:
Emissions of the F-gases
Statistics Denmark, The Ministry of Economic and Business Affairs:Statistical yearbook, Sales Statistics for manufacturing industries.
Danish companies: Audited Green accounts and direct information gathered from producers and agency enterprises
Solvents
Statistics Denmark, The Ministry of Economic and Business Affairs:Statistical yearbook, Production, import and export of NMVOC
10
Agriculture
Statistics Denmark, The Ministry of Economic and Business Affairs:Statistical yearbook, agricultural statistics.
Danish Institute of Agricultural Sciences, The Ministry of Food, Agriculture and Fisheries: Data on use of mineral fertiliser, feeding stuff consumption and nitrogen turnover in animals.
Waste
Danish Environmental Protection Agency, The Ministry of the Environment:Database on waste
Forestry
Danish Centre for Forest, Landscape and Planning, The Royal Veterinary and Agricultural University. Background data for Forestry and CO2 uptake by forest.
11
Inventory activities include
collecting activity dataselecting methods and emission factors appropriatelyestimating anthropogenic GHG emissions by sources and removals by sinks, implementing uncertainty assessmentquality assurance/quality control (QA/QC) activitiescarrying out procedures for the verification of the inventory data at the national level
12
Selecting methods and emission factors
On basis on the Key Sources Analysis a project evaluating the improvements necessary in order to fulfil the obligations according to the IPCC guidelines was carried out.
Result:Improvements of the emission inventories especially for industry, solvents and off-shore.
Prepare estimates in accordance with the methods described in the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories, as elaborated by the IPCC good practice guidance, and ensure that appropriate methods are used to estimate emissions from key source categories.
13
Implementing uncertainty assessment
Uncertainty
1) Uncertainty [%] Trend [%] Uncertainty in trend [%-age points]CO2 2,5 +12,5 ±1,9CH4 20 +3,3 ±9,3N2O 57 -25 ±14F-gases 48 +129 ±54GHG 6,8 +6,5 ±2,1
1. The uncertainty estimates includes stationary combustion plants, mobile combustion, fugitive emissionsfrom fuels, industry, solid waste and wastewater treatment and agriculture
14
General QA/QC
Ensure critical control points:transparency, consistency, comparability, completeness, accuracy (incl. correctness) and robustness of inventories
Quality control (QC) Quality assurance (QA)
Quality improvement (QI)
Quality planning (QP)
15
QA/QC procedures
Quality control (QC), secure fulfilment of critical control pointsChecking Point of Measuring (PM) including the following headlines:
•Provide routine and consistent checks to ensure data integrity, correctness and completeness;•Identify and address errors and omissions;•Document and archive inventory material and record all QC activities•Limit the negative consequences of any external or internal disturbance in data accessibility or inventory staff skills;•Verification by comparison of emissions, emission factors and uncertainty with other countries;
16
QA/QC procedures
Quality assurance (QA), document fulfilment of critical control pointsChecking Point of Measuring (PM) including the following headlines:
•National review: Emission inventory sector reports have been prepared and are send to national experts not involved in the inventory development for review.•International review

Level 1
TransparencyThe reasoning behind any value setting of external data has to beperceptible.
The data at level 1 has to be perceptible in relation to inventory workat higher levels, where questions regarding the output of theemission inventory can be assessed by tracking back to the baseset.
PM 1.1: One to one references for any external data sourcehas to be available for any single number in any data set.
PM 1.2: The data Id at level 1 has to be linked directly to theIds used in higher level data sets.
Example of the PM’s:QA/QC procedures
19
Future plans
• Complete formal agreements with other institutes• Review of reports for a few sectors by national experts.• Fully implementation of the QA/QC plan• Verification: Compare emission levels and emission
factors with other countries
• Inventory completeness: CO2 emission from use of lime and limestone for fuel gas cleaning, sugar production and production of expanded clay
