New Delhi, Jan 10: Greenpeace demonstrators’ highlighted the harmful impact of automobile emissions on global environment as the 'Auto Expo 2008' began here today.

The demonstrators staged a peaceful protest outside Pragati Maidan, the venue of the Expo.

They called for mandatory fuel efficiency standards for cars in India.

"We have only eight years to stop climate change. We are campaigning against the emission of harmful gases, and for fuel efficiency. We request the government to come up with a legislation to increase car fuel efficiency. The car industry should also cooperate and accept norms. If China can do it, so can we," said Ruchira Talukda, a Greenpeace demonstrator.

Car makers from across the globe are showcasing their creations at the exhibition in India, which is Asia's third largest automobile market.

Car majors in India are also jostling with each other with their latest variants at the expo.

Over 50 car makers that include the who's who of the automobile world are taking part in the exhibition, which is spread over 70,000 square meters.

About 150,000 auto buffs are expected to visit the show.

Rising incomes and new models are boosting car sales in India where only eight people in every 1,000 own a car, compared to 300-500 in many western countries.

Annual passenger vehicle sales are forecast to double to two million units by 2010. Small cars currently make up nearly two-thirds of the domestic market. Premium cars make up only about three per cent of sales now.

According to experts, by 2050, one in every six cars in the world will be driven by an Indian. (ANI)
