UNFCCC Workshop on National Systems

Institutional arrangement for GHG inventory in Norway

Norwegian Pollution Control Authority (SFT) is the designated entity responsible for the inventory and the reporting to UNFCCC

Statistics Norway (SN) is responsible for National Emission Model, and thus most of the emission calculation, documentation and archiving

Inventory planning in Norway – Bonn 11 – 12 April 2005 3

Statistics Norway (SN)

Norwegian Pollution Control Authority (SFT)

Reports from large point sources

CH4 from landfills

Activity data collected by other institutions (e.g. Road traffic, Petroleum Directorate)

Statistics collected by SN (e.g. Energy, Industry, Agriculture)

UNFCCC

Import of HFCs, SF6 and PFCs in products

Norwegian Institute on Land Inventory (NIJOS)

Legal arrangement

So fare the National System and the institutional arrangement have not been formalized by special legal arrangements

SFT’s responsibility has been established through a yearly mandate given by the Ministry of Environment

Formal agreements between SFT and Statistic Norway

Emission data from single plants are reported to SFT (mandatory)

Statistic Norway base their data collection on the Statistic Act

The institutional arrangements will be considered when establishing the National System

Quality assurance and quality control in Norway

Several QA/QC procedures have been established

Since 1993 methodologies and QA/QC procedures have been developed continuously

Not yet implemented a formal QA/QC plan, but most of the elements are established

The formal QA/QC plan will be fully implemented in 2005

Inventory planning in Norway – Bonn 11 – 12 April 2005 6

The existing QA/QC procedure (1):

SFT has the overall responsibility for coordinating the QA/QC procedures

Statistic Norway is responsible for the quality control system with regard to technical activities of the inventory preparation

Tier 1 general QC procedures are performed each year

Source category-specific QC procedures are performed for key sources, for both emission factors, activity data and uncertainty estimates (Tier 2)

Inventory planning in Norway – Bonn 11 – 12 April 2005 7

The existing QA/QC procedure (2):

SFT perform a basic QA expert peer review (Tier 1) by person who has not been involved in the calculations and the quality controls

Third party reviews will be establish for the hole or parts of the inventory

Several verification studies have been performed, such as comparison between countries and IPCC default:

o 1992: Compared Norway’s and Canada’s inventory

o 1998: Compared country specific and IPCC default method

o 2000: Compared Canada, NZ, Sweden and Norway

Inventory planning in Norway – Bonn 11 – 12 April 2005 8

Prioritization of the improvements

There are always resource constraints

The key sources approach is a key tool for the prioritization

Important to review the methods for all key sources regularly

A tier 2 key source analysis increase the importance on the most uncertain sources

A tier 2 uncertainty analysis increases the knowledge of the different steps in the calculations, but should not necessary be undertaken every year

Important to focus on QA/QC, documentation and archiving procedures

In Norway many of the improvements can be linked to events in climate policy development (1):

The introduction of CO2 tax in the North Sea made it

necessary to improve the activity data collection (1994)

Voluntary agreement with the metal industry resulted in a new methodology for PFC for the aluminium (1995)

The LRTAP agreement in 1999 made it necessary to improve the activity data for domestic marine movement and aviation

The method for actual HFC emission were developed when Norway introduced a tax on HFC import (1999 and 2005)

Inventory planning in Norway – Bonn 11 – 12 April 2005 12

In Norway many of the improvements can be linked to events in climate policy development (2):

Method for CH4 from landfills has been updated to meet new

regulation for deposal of organic matter (1999 and 2005)

To support the UNFCCC negotiations on HWP Norway developed a estimation methodology for HWP (2001)

Due to the establishment of the national emission trading scheme Norway has developed a regulation for estimating and reporting GHGs on entity level (2002-2004)

Inventory planning in Norway – Bonn 11 – 12 April 2005 13

When improving the inventory – important to distinguish between:

Short term technical improvements

Long term improvements where new research is needed(e.g.: N2O from agriculture soil)

Difficult for single countries to focus on the long term aspects alone – intergovernmental co-operation is needed

Inventory planning in Norway – Bonn 11 – 12 April 2005 14

How to improve inventory (1):

Establish QA/QC procedures and institutional arrangements according to the Guidelines

Secure predictable resources and funds for the development of the inventory

The Norwegian experience: Statistic Norway’s core role is important for the inventory system:

o Secure the data input, and hence increases the robustness of the inventory

o Statistic institutions can more easily adjust the collection of activity data when needed

Inventory planning in Norway – Bonn 11 – 12 April 2005 15

How to improve inventory (2):

Limit the number of agencies involved in the inventory

Produce preliminary emission figures for preceding year

Establish tiers 2 uncertainty analysis :

o Not only as a tool for prioritization and identification of key sources, but

o also a tool to detect the steps in the calculation where improvements are needed

To integrated GHG and LRTAP inventory

Verification studies, e.g. cross-country reviews

Inventory planning in Norway – Bonn 11 – 12 April 2005 16

How to respond to ERT comment:

Important to establish a procedure to respond to the comments

Important to start early with the implementation of proposed improvements (before the final report has been published)

Often the comments are focusing on details – but still important respond to increase the confidence in the inventory

Normally ERT’s comments are well known by the Party

But the ERT reports give additional arguments for prioritization when domestic resources are constraint
