The New Sector “Industrial
Processes & Product Use (IPPU)”
Bonn, 20. May 2005

Outline
 Why combine “Industrial Processes” and
“Solvent and Other Product Use”?
 New sector structure
 Non-energy use of fossil fuels
 Boundary between “Energy” & “IPPU”
 New emission factors
 Conclusions

Combining Industrial Processes
and Solvent Use
 „Solvent & Other Product Use“ comprised only 4
pages of guidance in 1996 Revised Guidelines!
 “Industrial Processes” in 1996 Guidelines
already covered some product emissions
 2000 Good Practice Guidance did not address
„Solvent & Other Product Use“ at all
 Need for consolidation of approaches and
balanced presentation of information
 Recommendation from Scoping Meeting to
combine “Industrial Processes” & „Solvent and
Other Product Use“ into IPPU-Volume

New sector structure
New sources added
New gases added
Re-grouping of sources
More coherent source categories
Possibly some adjustments required
based on relevance of sources and new
sources becoming know

Other Product Use

Non Energy Use of Fuels
Relevant sources included more
clearly
More differentiated factors for
„oxidation during use“
Accomodation of solvent use

Boundary between Volume
„Energy“ and „IPPU“
 Operational definitions of energy versus
industrial process emissions exist in 1996 GL
and FOD 2006 GL
 More consistent approach desirable in principle
e.g. in steel, refineries & petrochemical industry
 However, there are varying existing national
practices and limitation to data availability
 Scoping Process recommended to maintain the
flexibililty
 Future national intensity targets and other ghg
reporting scheme may require more consistency

New Emission Factors
 New sources and gases as well as technological
development and improved knowledge result in
the need for new emission factors (tier 1, 2, 3)
 Proposed time-dependent tier 1 emission factors
e.g. for HFC-23 and Electrcical Equipment
Problem of free riders
• Sets of new emission factors e.g. for
semiconductors, foams, refrigeration and
electrical equipment
Expert judgement versus full traceability as
required for EFDB

Conclusions
 Significant gain of knowledge about sources and
gases since 96/00
 Strong participation from industry
 Dynamic sector with rapid technological change
 Policies and voluntary actions already show a
strong impact on emissions from several sources
 Emission are sometimes physically unbound ->
strong requirements regarding transparency and
traceability of emission factors
 Challenge to maintain the evolutionary approach
