GHG Inventory Issues and Concerns (Fuel
combustion)

2
Outline

• Status of energy GHG emissions
• Issues and recommendations
• Challenges

3
Status of Energy GHG emissions

• Submission in 1NC
• Key sources

4
Issues and Recommendations

• Localization
• Emission factors (e.g. coal and other fuel types)
• Technologies (e.g. alternative fuels)
• Study local fuel types and technologies (e.g.
  fuel composition) and develop local emission
  factors.

5
Issues and Recommendations

• Institutionalization of the Overall Energy
  Balance (OEB) Sheet
• OEB adapted in such a way that it will contain
  all the information necessary for the computation
  of GHG emissions in the energy sector.

6
Issues and Recommendations

• Data readily available from DOE but are highly
  variable due to continuous updates in fuel
  consumption and allocations.
• Regularize submission schedules rationalize data
  submission protocols especially from oil
  companies and private sector to various gov
  agencies

7
Issues and Recommendations

• Incomplete database on household consumption of
  biomass fuels such as wood/woodwaste, charcoal,
  agriwaste and other biomass/waste.
• Only basis is 1989 and projections made for 1995
  and 2000, from UNDP-ESMAP study. DOEs Household
  Energy Consumption Study (HECS) commenced only in
  1995.
• Institutionalize/regularize surveys and studies
  on household fuel consumption (e.g. biomass and
  conventional fuels)

8
Issues and Recommendations

• Major data gaps in the transportation subsector
• Need to update VECP EFs for new vehicles and fuel
  types
• Type and technology of registered vehicles
• Number of kilometers traveled per year
• CO2 in emissions testing, MVIS
• Institutionalize comprehensive registration
  process containing all the necessary and
  important information for each registered vehicle
  in every LTO registration branch.

9
Issues and Recommendations

• Institutionalization of data flow and information
  systems within DOE
• Develop structured linkages within the DOE
  specifically with the Demand Analysis and
  Planning Division (DAPD), main data center of the
  department, and the Environment Division which
  computes and projects national CO2 emissions from
  the energy sector.

10
Energy inventory challenges

• Power reform (entry of private sector)
• Natural gas, biofuels
• QA/QC
• Uncertainty analysis
• Level of aggregation (geographic too)
