obility is needed for everything we dotoday. The United Nations ClimateChange Summit in Cancún is just anotherexample of important gatherings madepossible by transport, from the planes, buses andautomobiles that move participants to the conferencevenue; to the commercial vehicles that deliver food andgoods. The same is true for economic activity: whetherclose to home or far away, transport affects the lives of everyone.With increasing economic development around theworld and continuing globalisation, mankind faces anera of unprecedented demand for transport. Roadtransport remains the largest supplier of mobility. Wewill not be able to do without it. But we will need toaddress the challenge of rising CO2 emissions, with noless than a transformation of all parts of the transportsector, including autos, fuels, roads and more.As leaders of automotive industry groups, we know thatvehicle technology will play an important role in this,and manufacturers are investing heavily in a range oftechnologies to do their part. In addition to constantlyimproving the internal combustion engine, they areintroducing and further developing clean diesel,alternative fuel, hybrid, all electric and fuel cellvehicles. All of these technologies will be important forreducing emissions in the short-, mid- and long-term.However, improving technology exclusively has asignificant drawback: with the turnover of the vehiclefleet taking 15-20 years, a long time is required fortechnology to have a significant effect on emissions.Measures besides vehicle technology that canimmediately reduce CO2 from the whole road transportsector are therefore indispensable. They can ensurethat CO2 emissions are reduced swiftly - and cost-effectively. Together with improving technology, theyconstitute what we call the integrated approach toemission reduction.This integrated approach starts with trafficmanagement and infrastructure. Electronic or "smart"mobility aids, as part of Intelligent Transport Systems,can do much to enhance traffic flow. "Co-modality",which is the good linkage between different modes ortypes of transport, increases the efficiency of thetransport system as well. Drivers can reduce the fuelconsumption of their vehicle instantly by adopting eco-driving techniques. The uptake of new and improvedtechnologies should also be encouraged by appropriatefiscal and other incentives, which compensate part ofthe additional costs consumers will face when buying,for instance, electrically chargeable vehicles.
