Workshop on
Inventories and Projections of
Greenhouse Gas Emissions from
Waste
Working Groups I and II of the EU Climate Change
Committee
2-3 May 2005
EEA, Copenhagen
Background
In 2002, a workshop was held to discuss approaches in calculating and
reporting projections of energy-related CO2 emissions followed by a workshop
on emissions in agriculture in February 2003 and one on emissions of
greenhouse gases from aviation and navigation. The sectoral workshops were
very successful in helping Member States to share best practice, providing
information for on-going analysis under the Monitoring Mechanism and in
making recommendations to improve reporting in future. The need for the
Community to accurately gauge its progress towards meeting its UNFCCC
and Kyoto commitments, which is the mandate for the Monitoring Mechanism
provided by Council Decision 280/2004/EC, is fundamental. It was suggested
that further sectoral workshops be held on other important topics and
1
estimating GHG emissions from waste was identified as an area in need of
improvement.
One of the main objectives for such a workshop is the provision of an
opportunity to learn about the methods used for inventories and projections in
the different Member States, to share information, experience and best
practice. It would also be very helpful to compare the parameters chosen in
the estimation methodologies across EU Member States. Finally the
workshop would be an opportunity to compare emissions and methods used
for GHG inventories with data and methods for EPER and would also
strengthen links between assessment of air pollution under the IPPC and
emissions under the UNFCCC. The workshop will provide an opportunity to
discuss potential methodological changes or improvements of the draft 2006
IPCC inventory guidelines (the workshop will take place after the first expert
and government review of the first order draft of the 2006 IPCC inventory
guidelines).
The draft agenda for the workshop and guidelines for the presentations that
should be delivered by national projections or inventory expert are included in
Annex I & II of this document. It is suggested that only some Member States
give a full presentation with additional time afterwards for the others to give
additional information.
The first day of the workshop will focus on inventories. Areas to be covered
include:
 Estimation methodologies for emissions from solid waste disposal (CRF
6.A) under UNFCCC
 Estimation methodologies for emissions from wastewater handling (CRF
6.B)
 Estimation methodologies for emissions from waste incineration (CRF 6.C)
 Estimation methodologies for emissions from other sources (composting,
biological-mechanical treatment etc.) (CRF 6.D)
 Estimation methodologies for emissions from landfills for the EPER
 Development of 2006 IPCC Guidelines in the waste sector
The main aim will be to give recommendations to improve transparency,
accuracy and completeness of reporting. Good Practice in inventory
preparation will also be discussed.
The second day of the workshop will focus on projections and follows a similar
format. An additional area that needs to be covered is the inclusion of the
effects of policies and measures in the projections. The aim will be to make
recommendations to improve clarity and completeness of reporting of
projections. Methodological improvements, particularly in including the effect
of policies and measures, can also be discussed.
Although the topics are separated into two days, participants are encouraged
to stay for both days to further facilitate communication between experts.

Invited experts/organisations
The workshop is targeted at experts who have direct experience in compiling
and analysing GHG emission projections and inventories from the waste
sector. The aim is that experts from all Member States are present at the
workshop and that experts for inventories and projections attend the whole
workshop to facilitate exchange of information and experience.
Decision makers in the field of Climate Change are invited as well to use the
workshop as an information exchange opportunity and to deliver input for the
discussions on further steps for improved procedures within the EU.
Organisational
The workshop will be held on 2-3 May 2005 at the EEA in Copenhagen. The
agenda for the workshop and the proposed outline of presentations are
included in Annexes I & II of this document.
Registrations should be sent to Bitten Eriksen (Bitten.Eriksen@eea.eu.int) by
6 April 2005.
