2. Round Table 1 – How will advanced ICE vehicles contribute
to meeting the CO2 emission targets
Executive Summary
•Trucks contribution in the low global CO2 emissions is 3,5%
•Based on an increase of vehicle fuel efficiency and enlargement of the
transportable payload, Mercedes-Benz has shown an increase of transport
efficiency by nearly 50% since 1960
•Latest with the application of Euro VI, the regulated emissions such as NOx and
PM of heavy duty vehicles will be negligible compared to other emission sources.
No further emission legislation is necessary.
•There is no need for legislative activities to restrict CO2 emissions by trucks
because of the high impact of fuel prices on the total costs of ownership
•Top levers to reduce CO2 over the next 10 years are infrastructure and operation.
