Title: GHG Inventory Issues and Concerns (Fuel combustion)


1
GHG Inventory Issues and Concerns (Fuel
combustion)
  • Jose Ramon T. Villarin
  • Shanghai, China
  • 8 Feb 2005

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)

Thank you.
  • Happy New Year of the Rooster!

Reference vs sectoral approaches
  • Reference (top-down) 49,999.51 kt CO2
  • Sectoral (bottom-up) 47,335.37 kt CO2
  • Difference 2,665 kt CO2
