2. A - Methodology applied for road transport
Outline
A - Methodology applied for road transport
B – From SNAP to NAMEA

3. Traffic conditions and parameters
A. Road transport methodology
Method: EMEP-EEA → COPERT 4 model
Emission & consumption Factors: COPERT, according to
vehicle type, regulation, average speed, etc.  IPCC Tier 3
A very detailed methodology (covering GHGs and non GHGs).

5. Fleet of vehicles (1/2) (number of vehicles according to EU regulation)
Passenger cars

6. Fleet of vehicles (2/2) (number of vehicles according to EU regulation)
High Duty Vehicles

7. Traffic parameters Total mileages (vehicle*km):
CCTN mileages (traffic estimations on the territory, not based on purchase of fuel) by vehicle type used as reference but adjusted on fuel sold (*).
Annual average mileage per vehicle:
Type and age of vehicles taken into account (INRETS studies),
Balanced mileages with the above total mileages (*).
Traffic share on urban, rural, highway conditions:
Balanced on global share from CCTN (all vehicles together).
Average speeds:
Speed fitting to ensure the energy balance between the theoretical calculation and the fuel sold.

8. Energy data for road transport
Energy balance process within COPERT:
General energy balance procedure to ensure finally a fuel sold approach
Fuel sold versus estimated consumption in France (CCTN):
Use of fuel sold data (road transport use) as requested for national emission inventories.
Boundary balance:
the gasoline consumption estimation (CCTN) on the territory is generally higher than the fuel sold
the diesel consumption estimation (CCTN) on the territory is always lower than the fuel sold %

9. B. From SNAP to NAMEA Methodology Emissions by SNAP codes
Emissions by NAMEA codes (NACE)
Distribution ratios (SNAP -> NAMEA)

10. 0701 : Passenger cars (PC) Sources :
Number of PC by NAF (NACE) codes for professionals and number of private PC (published annually by the transport Division of the Department for statistics of the French Ministry of Ecology(SOeS)),
Average mileage by socio-professional categories (survey): households, farmers, craftsmen, merchants, companies, public services.
Methodology :
Emissions are distributed in NAMEA codes by weighting them by traffic (veh.km).

11. 0702 : Light duty vehicles (LDV)
Sources :
Number of LDV by NAF (NACE) codes for professionals and number of private’s LDV (published annually by the transport Division of the Department for statistics of the French Ministry of Ecology(SOeS)),
Average mileage by socio-professional categories (survey): private, farmers, craftsmen, merchants, companies, public services.
Distribution between diesel and gasoline LDV by users (studies realized periodically).
Methodology :
Emissions are distributed between NAMEA codes by weighting them by traffic.

12. 0703 : Heavy duty vehicles (HDV)
Sources :
Number of HDV : given annually by CITEPA’s fleet model (OPALE),
Tones.kilometers transported by type of products and type of transport (own account and other account): published annually by the transport Division of the Department for statistics of the French Ministry of Ecology(SOeS),
Methodology :
Emissions of HDV and buses are separated,
Own account transport and transport for others are separated based on data on ton.kilometers transported,
transport for others is attributed to NACE ,
own account transport is split out across the different NAMEA codes based on data on ton.kilometers transported by type of product.

13. 0703 : Buses and coaches (B&C)
Sources :
Number of B&C: given annually by CITEPA’s fleet model (OPALE),
Number of veh.km used for own account: published periodically by French transport statistic service,
Number of employees in firms which have more than 500 employees by type of products (industrial statistics : National Institute of Statistics and Economic Studies (Insee)).
Methodology :
Emissions of heavy duty vehicles and buses are separated,
Own account transport and transport for others are separated based on data on vehicle.kilometers,
transport for others is attributed to NACE ,
own account transport is split out across the different NAMEA codes based on data on number of employees (firms that have more than 500 employees: hypothesis).

14. 0704, 0705 (two wheels)
Sources :
Number of restaurants offering home delivery (e.g. pizzerias),
Number of owned State motorcycles : published annually by the transport Division of the Department for statistics of the French Ministry of Ecology(SOeS),
Number of motorcycles belonging to the postal services (given by LA POSTE the French public postal service firm).
Methodology :
Emissions of SNAP 0704 (motorcycles < 50 cm3) is separated between NACE 53 (postal services), (food services) and households based on data on the number of mopeds & motorcycles (< 50 cm3).
Emissions of SNAP 0705 (motorcycles > 50 cm3) is separated between NACE 84 (public administration) and households based on data on the number of motorcycles (>50 cm3).
