The use of individual vehicles is growing strongly all over the world, driven primarily by rising incomes..

• In emerging and developing countries: the rise in the standard of living is accompanied by a significant increase in mobility requirements.  By 2030, emerging countries are expected to account for nearly two-thirds of all personal travel worldwide.             
• In OECD countries, personal travel continues to increase, but at a slower pace (+1.2% per year).      

Disparities in access to transport

• Possession of or access to motorized vehicles is increasing all over the world. This increase applies not just to cars but also to two-wheeled vehicles, which make up 70% of vehicles on the road in countries such as China.  
• Between now and 2030, however, disparities in access to transport will remain between: 
  
        - industrialized countries and emerging countries, 
        - urban populations and rural populations, 
        - different ethnic groups, 
        - the elderly or handicapped and the rest of society.             

Promoting access to mobility for everybody is thus a key objective for the future.

Reducing emissions of conventional pollutants, such as CO, NOx, sulphur particles and lead.

• In OECD countries, significant progress has already been made in these areas. By 2030, these emissions will be further reduced by a significant amount.            
• In emerging countries, cutting pollutant emissions by 2030 is a major challenge that must be taken up by all those concerned.

Progress can be expected over the long term, with:

• the renewal of the vehicle parc,
• the widespread use of unleaded fuel worldwide,
• the use of emission-reducing technologies, adapted to two-wheeled vehicles.     

Increase in greenhouse gas (GHG) emissions 

Two factors are expected to have an impact on emissions in the coming years: 

• a fall in fossil energy consumption for vehicles with the highest emission levels, such as aircraft and trucks, thanks to the advent of new equipment (reducing aircraft emissions by around 29%);
• a significant rise in transport activities (as much as 400% for air traffic). 

GHG emissions can thus be expected to increase considerably by 2030, particularly in emerging countries, despite relative stability in OECD countries. According to the Mobility 2030 report, it will be extremely difficult to achieve a large-scale reduction of GHG emissions by 2050.

In emerging countries, the increase in the number of vehicles on the road could bring about an increase in noise pollution and traffic congestion if road infrastructure is inadequate.
