The cost-effectiveness approach : 

The cost-effectiveness approach Models help to separate policy and technical issues:

Emission sources (1) : 

Emission sources (1) Several sectors: energy industrial production transport solvent use agriculture Activities fuels (17) processes (~70) other (e.g., livestock farming, paint use)

Emission sources (2)Criteria for aggregation : 

Emission sources (2)Criteria for aggregation RAINS applies five criteria: Importance of source (>0.5 percent in a country) Possibility for using uniform activity rates and emission factors Possibility of establishing plausible forecasts of future activity levels Availability and applicability of “similar” control technologies Availability of relevant data In spite all that effort….about 1500 emission categories included.

Emission sources (3) : 

Emission sources (3) Level of detail (1): Energy: Power plants (by fuel and furnace type) Industry (by fuel and furnace type) residential combustion (by fuel and installation type) Industrial processes: NMVOC module (over 20 sectors) PM module (over 40 sectors) Transport: Road (two-wheelers, cars, trucks; by fuel and engine type) Off-road (several categories; by fuel) Non-exhaust (brake, tyre, and road wear and evaporative) Shipping (inland shipping, coastal zone, international)

Emission sources (4) : 

Emission sources (4) Level of detail (2): Agriculture: Animal categories (by housing type) N-Fertilizer application (urea and other fertilizers) Industry Transport Other Other: NMVOC module (e.g., evaporative losses from fuel distribution, paint use, waste burning, etc.) PM module (agriculture, waste burning, storage and distribution of fuels and industrial products, etc.)

Emission sources (5)EXAMPLE: VOC processes/sources : 

Emission sources (5)EXAMPLE: VOC processes/sources Solvent use: Dry cleaning and degreasing Decorative paints Industrial paint application Vehicle manufacturing and repair Printing Manufacture of paints, inks and glue Preservation of wood Chemical industry Tyre production Pharmaceutical industry Domestic use of solvents Other Oil production and use: Off- and on- shore exploration Refineries Storage of crude and products Distribution of products (e.g., gasoline stations) Mobile: Evaporative emissions from gasoline engines Exhaust emissions from road and off-road vehicles

Method - Calculating emissions : 

Method - Calculating emissions where: i,j,k,m,y Country, sector, fuel, abatement technology, pollutant Ei,y Emissions in country i and pollutant (species) y A Activity in a given sector ef “Raw gas” emission factor effm Reduction efficiency of the abatement option m Xm Implementation rate of the considered abatement measure m

Method - Information on the level of activity : 

Method - Information on the level of activity Historical (1990,1995,2000) – statistics, communication with national experts, own assessments Forecasts (until 2030) – energy models, agricultural models, countries’ submissions

Method – emission factors : 

Method – emission factors “Unabated” emission factors for anthropogenic sources only Country/region specific factors taken into account wherever possible, i.e.: For SO2: fuel characteristics For PM: fuel and installation characteristics For NH3: N-excretion and volatilization, production efficiency, housing period For NMVOC: climatic conditions, volatility of fuels, solvent content of products

Method – abatement techniques : 

Method – abatement techniques Economic and technical information for “technical” measures For most techniques efficiency assessed from literature and communication with experts, however, country/region specific factors taken into account when necessary, i.e.: For NH3: geophysical conditions, feeding strategies For NMVOC: sector “composition”, solvent content of products Introduction of “applicability” parameter, i.e., maximum technically feasible application rate of control option Actual and projected penetration rate of control technology

Input data for projections : 

Input data for projections Driving forces National information on projected energy (21), agricultural (18) and other activities European models: Energy and macroeconomic assumptions - PRIMES, Agriculture - CAPRI, FAO, EFMA, Transport - TREMOVE Other sources, e.g., industry (solvents), CEPMEIP Parameters Penetration of abatement techniques Changes in efficiency of production Applicability of abatement

Problems and uncertainties(SOx, NOx, PM) : 

Problems and uncertainties(SOx, NOx, PM) Transport – Veh-km and vehicle numbers often inconsistent with fuel consumption. Projections of vehicle numbers available only for a few countries Differences in reporting transport emissions – fuel sold vs. fuel used. For NEC fuel sold was taken PM estimates – some countries don’t report PM2.5 and PM10; often not all sources included Poor information on size an chemical speciation for several sources Larger uncertainty for un- or poorly regulated sources, i.e., industrial processes, off-road, domestic Availability of data on biomass use ‘Real life’ reduction efficiencies, e.g., NOx-HDT, PM-DPM

Problems and uncertainties(NH3) : 

Problems and uncertainties(NH3) For few countries issue of base year statistical data; inconsistencies between national and international data Poor information on housing systems in place and their future evolution Contradictory information on how existing legislation is or will be implemented Emissions from non-agricultural sources not always reported For a number of countries better information on current practices could lead to significant improvements, i.e., development of national emission factors

Problems and uncertainties(NMVOC) : 

Problems and uncertainties(NMVOC) Unsatisfactory resolution of emission reporting format does not allow for verification of emissions from solvent use Evaporative emissions from cars, residential combustion and solvent use contribute most to the uncertainty of 2000 estimates; the latter two retain their importance for 2020 calculations Better information on combustion technology used in residential sector essential for future work National projections for emissions from solvent use remain an exception; industry provided their perspective for a number of sectors and MS Emissions from open biomass burning often not included Better collaboration between industrial associations and national emission experts could lead to significant improvements

Sources of uncertainty : 

Sources of uncertainty Activity projections Expected penetration of abatement (interpretation of law) Maximum penetration of abatement Simplified models matter more for sectoral, regional allocation Significant uncertainties remain Poor information on size an chemical speciation for several sources Larger uncertainty for un- or poorly regulated sources, i.e., industrial processes, off-road, domestic Availability of data on biomass use Sea shipping and recreational shipping emissions, ‘Real life’ reduction efficiencies, e.g., NOx-HDT, PM-DPM Questions of applicability of western methods (and assessments) to the non-EU25 countries largely remain.
