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

2. 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

3. 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.

4. Uncertainty information
Point value

5. “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

6. 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.

7. CO2 Capture and Storage
Stationary
Combustion
New
Chapter
IPPU

8. CO2 Capture and (Transport &) Storage

9. 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.
