Evolution of Emission Standards


Urban air quality has not been

improved in the same manner

Regulatory test cycles don’t seem to be representatives of

real world in use vehicle operation

Emission tests are more like cycle beating test


In order to minimize the effects of

transport emissions on urban air

quality

Emission standards must be based on

real world in use emissions

although it is challenging.

QUANTIFICATION OF TRANSPORT EMISSIONS

it is crucial to reliably quantify and determine the

respective contributions of the different classes of

vehicles to the total emissions.


PEMS can minimize the uncertainities

while determining the respective

contribution of transport beside industry

and residential heating and others to

urban air quality


QUANTIFICATION OF TRANSPORT EMISSIONS


Emission Factors that are developed from Real World data

minimize the uncertainties in emission inventorying and

therefore the contribution of transport to urban air

quality can be better determined.

Policy makers can propose reliable measures to improve

urban air pollution.


Real-world emissions to be introduced

in EURO VI

2008 Call of Sustainable Surface

Transport (FP7)

For road transport research will aim by 2020 at a

50% CO2 reduction for new passenger cars and

light-duty vehicles and 30% for new heavy-duty

vehicles (both based on 2003 figures).

Reduction of exhaust and local emissions to reach

near-zero-emission levels


RESULTS

It is crucial to quantify and inventory reliably

the respective contributions of different

sources (transport , residential heating and

industry) to total emissions to study

the measures that the policy makers have

to propose in order to set and also meet

the urban air quality targets.

PEMS can be remedy for reliable

quantification of transport emissions
