Despite technological advances, transport is not developing in sustainable ways. The transport sector – excluding international aviation – is currently responsible for about a quarter of total UK carbon dioxide emissions, 80 per cent of this is contributed by road users. The annual global greenhouse gas emissions (GHG) by transport stand at 13 per cent of the total.

In the UK, the central projection is for traffic to grow by 26 per cent between 2000-10, implying an annual average increase of 2.3 per cent over the decade.

Overall, there were 33 million vehicles registered for use on UK roads in 2006, including cars, vans, taxis, buses and trucks. Globally, the market for new passenger cars is increasing by some 3.8% to 50.7m units annually. The biggest contribution comes from developing regions like Asia (excludes Japan) and the growth of that region - especially China - forms a clear and central theme in this forecast. The contribution of the Pacific Rim countries to the growing world market is by 2009, almost an additional five million units. China alone accounts for around 80% of that increase as its annual car market expands to six million units by the end of the forecast period.

We need to minimise the impact of transport on people and environment. By the year 2050, the rate of growth in transport will bring damages to the climate change to an estimated $300 billions per year.


There are a number of issues which need to be addressed to reduce carbon dioxide and other emissions from the road transport sector:

• Adopt new emissions-reducing technologies for cars and trucks.
• To improve the design and shape of the internal combustion engine.
• Develop sustainable transport by taking into account the level of pollution and environmental quality.
• Develop alternative fuel cars using sources like liquefied petroleum gas (LPG), liquefied natural gas (LNG), hydrogen, electricity, alcohol, fuel cells, hybrid, solar power, bio-diesel.
• Encourage and promote public transport, thereby reducing demand for vehicle travel.
• Car sharing, to maximise car occupancy, lessen congestion and improving air quality.
• Better facilities for cyclists and walkers.
• Reduce the need to travel to out of town stores, and have work places closer to home.
