Sulfur content of gasoline

Sulfur content of diesel

Main challenges we face

n  Compliance supervision hasn’t been put in place

n  Control measure on VOC emission from gasoline vehicles is lagged

n  Attention on pollution from alternative fuel is not enough

Challenges from Compliance

New challenges from off-road

mobile source    

Non-­‐road  mobile  source  is  mainly  composed  by  diesel  engines,  which  emit  higher  NOx  and  PM  that  basically  equivalent  to  on-­‐road  mobile  source  

Environmental compliance supervision for off-road mobile source is just starting

Engineering equipment

p  no registration system p  cross-area operating p  no management system p  responsible department is still unclear  

NOx

Port and vessel pollution

Shanghai

SO2, NOx and PM2.5 emission from ports and vessels accounted for 12.46%、11.6% and

5.6% of total city emissions

Hong kong Vessel emission is the top source

of SO2, NOx and PM10 emission

SO2

NOx PM10

Countermeasures and suggestions    

n  To revise “Law on the Prevention and Control of Air Pollution” p  To clear responsibilities and works of each p  To cover all mobile sources p  To intensify responsibilities of manufacturers p  To manage vehicles and fuels as one system p  To develop life-cycle environmental supervision and establish recall system

n  To establish “Motor Vehicle Pollution Prevention and Control Rules”

p  To develop detailed rules according to“Law on the Prevention and Control of Air Pollution" and make it more practicable

To consummate laws and regulations

To establish more stringent emission standards

To establish China VI emission standards

—more practicable for Chinese situation

—more stringent requirements on compliance

supervision

—more flexible

—better for technology and industry upgrading

 

National Action Plan of Clean Diesel Engine

n  Implement objective p Commercial diesel vehicles p Engineering equipments, garden equipments, agricultural equipments and port-use equipments

p Inner-river and offshore vessels p Diesel fuels for vehicle, non-road engine and vessel

n  key projects p  Clean transit vehicle plan p  Clean equipment plan p  Clean shipping plan p  Clean diesel fuel plan
