Experience with GHG emission projections for energy sector
in LATVIA
Workshop on emissions projection6-8 September 2004, UNFCCC Secretariat, Bonn
Janis RekisLatvian Investment and
Development Agency
History of MARKAL use for emission projections in energy sector
• Started in 1995• 2nd National Communication• 3rd National Communication• Projections for SO2, VOC, NOx• and now …
Modelling approach
• Bottom-up rich technology optimization model
• Spread of action between supply and demand
• Emissions taxes and constraints• Estimate system costs• Sensitivity analyses

Issues (1)
• Reporting– Generic tables (results, assumptions etc.)
• Problems– Emission factors for new fuels– Energy useful demand projections (how to
link with macroeconomic forecast)– Possibility to deal with uncertainty with
stochastic analyzes– Discrepancy between structure of energy
balance and inventory (ex. off-road)
Issues (2)
Notwithstanding to resent development in CC policy field
• National system isn’t yet established
• Lack of coordination between involved institutions
• Lack of financial capacity
