What’s New in the Energy Volume IPCC 2006 Guidelines Bonn, 18 may 2006 Tinus Pulles TNO, Netherlands

Overview No “real” changes since the revised 1996 Guidelines What’s new? Clear separation of Sectoral Approach and Reference Approach Clear treatment of non-energy use of fuels New chapter on CO2 Capture and Storage Methods for abandoned coal mines New methodologies and emission factors to reflect developing country circumstances as well Improved decision trees facilitating more accurate emission estimation Uncertainty information for all default values

Energy sector overview The energy sector comprises: fugitive emissions during exploration, exploitation of primary energy sources, conversion of primary energy sources into more useable energy forms in refineries and power plants transmission and distribution of fuels use of fuels in stationary and mobile applications.

Uncertainty information Point value

“Sectoral Approach” vs “Reference Approach” Estimate to be included in national inventory Part of QA/QC Independent check of the sectoral approach Fuel used x Emission Factor Tier 1 Tier 2 Tier 3 National Carbon balance, based on (primary) fuel combustion and international trade (imports, exports) with corrections. All gases CO2 only Effort Error

Non-Energy use of Fuels By definition: Non-Energy Use is not dealt with in “Energy” but in “Industrial Processes and Product Use”. Sectoral Approach uses “Fuel Combusted”. A correction for Non-Energy Use is implemented in the Reference Approach to deal with the carbon stored in products The 2006GLs would help segregate energy and non-energy emissions from sectors such as iron and steel.

CO2 Capture and Storage Stationary Combustion New Chapter IPPU

CO2 Capture and (Transport &) Storage

Abandoned Coal Mines Closed, or abandoned, underground coal mines may continue to be a source of greenhouse gas emissions for some time; Tier 1 and Tier 2 methods, based on a database of abandoned mines are provided and default emisison factors are given.
