The automotive industry designs, develops, manufactures, markets and sells motor vehicles worldwide. In 2008, more than 70 million motor vehicles, including cars and commercial vehicles were produced worldwide.
In 2007, 71.9 million new cars were sold worldwide: 22.9 million in Europe, 21.4 million in Asia Pacific, 19.4 million in the US and Canada, 4.4 million in America Latin America, 2.4 million in the Middle East and 1.4 million in Africa. The markets in North America and Japan were stagnant, while those in South America and other parts of Asia grew strongly. Among the major markets, China, Russia, Brazil and India recorded the fastest growth.
About 250 million vehicles are used in the United States. Worldwide, there were about 806 million cars and light trucks on the road in 2007; They burn over 260 billion US gallons (980 million m3) of gasoline and diesel per year. The numbers are increasing rapidly, especially in China and India.  According to some, urban transport systems based around the car have proved unsustainable, consuming excessive energy, affecting the health of populations and reduce the level of service despite increasing investments. Many of these negative impacts fall disproportionately on those social groups who are less likely to own and drive cars. The sustainable transport movement focuses on solutions to these problems.
In 2008, with the rapid rise in oil prices, industries such as the automotive industry undergo a combination of pressures on commodity prices and changes in consumer buying habits materials. The industry is also facing increasing external competition from the public transport sector, as consumers re-evaluate their use of private vehicles. Almost half of the fifty-one light vehicle of the United States should close down in the next few years, with the loss of 200 000 jobs in the sector, in addition to the 560,000 jobs lost this decade. In combination with strong growth in China in 2009, China became the largest producer of cars and the world’s largest market. Sales in China in 2009 reached 13.6 million, a significant increase over the one million domestic car sales in 2000. Since then, however, even in China and other BRIC countries, decreases the production of new cars.
Established alternatives for some aspects the use of the car include public transport such as buses, trolley buses, trains, subways, trams, light rail, cycling and walking. carpool arrangements and carpooling are also increasingly popular in the United States and Europe. For example, the United States, some carpool services have experienced double-digit growth in turnover and growth between 2006 and 2007. The services, such as car sharing offer residents to “share” a vehicle rather than own a car in already congested neighborhoods. bike sharing systems have been tried in some European cities, including Copenhagen and Amsterdam. Similar programs have been tried in many US cities. Other individual modes of transport, such as fast transport staff could be a viable alternative to automobiles if they prove to be socially accepted.
