The rapid rise in motorcycle numbers and continued operation of old three-wheelers remain Asia's main challenges in effecting emissions cuts to deal with climate change, transportation experts say.
Bert Fabian, transport program manager of the Clean Air Initiative for Asian Cities (CAI-Asia), said most small towns in Asia still used two- and three-wheel vehicles as their main mode of public transportation.
"More people prefer to use motorcycles and three-wheelers in urban areas, since they're cheaper and consume less fuel. But their emissions are the major challenges," he told participants at the Better Air Quality 2008 (BAQ 2008) conference here Monday.
A joint study this year by CAI-Asia and the Asian Development Bank (ADB) lists Malaysia, Vietnam, Thailand, Indonesia and the Philippines as the five Asian countries with the highest motorcycle ownership.
The study shows Malaysia has 300 million motorcycles as of 2008, compared to 275 million in 2005. It is estimated the number will rise to 390 million in 2015.
Indonesia, home to more than 230 million people, currently has 125 million motorcycles -- an increase from 80 million in 2005 -- with CAI-Asia predicting motorcycle ownership will grow to 150 million by 2012 and 200 million by 2025.
"The number of motorcycles is also rapidly growing in the Philippines. This is directly related to the deterioration of public transportation," Fabian said.
"The rising number of vehicles will boost fuel consumption."
CAI-Asia also highlighted the use of aging vehicles, still widely used across the region.
A 2005 study revealed the aging three wheelers in Indonesia, more popular as bajaj, had an average age of 25 years, compared to nine years in Thailand.
The average age of cars in both countries remained at between six and 10 years.
About 900 transportation experts, policymakers and stakeholders from around the world have gathered in Bangkok until Friday to discuss efforts on reducing air pollution and cutting harmful emissions from the transportation sector.
The World Health Organization estimates 800,000 people die prematurely due to exposure to urban air pollution. Of this figure, some 50,000 are in Asia.
CAI-Asia said emissions of air pollutants, including particulate matters (PM10) and carbon monoxide (CO) from the transportation sector, showed a declining trend due to the use of cleaner technologies and fuels under the implementation of the Euro standard.
"But CO2 emissions are a different story. There is no up-and-down trend. It keeps rising because of rampant fuel consumption," Fabian said.
He proposed three efforts to deal with such emissions: reducing emissions per kilometer of trip, cutting emissions per unit of transport, and slashing the number of trips.
"We can get the most emission cuts by reducing the amount of traveling. However, it takes behavioral changes for the people (to do so)," he said.

Hi,
I agree with your perspective, but is not Climate Change is a Type of Air Pollution?
When people think of air pollution, they most often associate it with the sort of dirty discharge that can be readily seen coming from the smokestacks of coal-fired plants or even the particulate matter that is emitted from automotive tailpipes. However, the most common and potentially dangerous gases that threaten life on Earth are actually greenhouse gases.
Carbon dioxide and methane, together, account for about 30% of the "greenhouse effect" that, at levels that had been steady since the end of the last ice age, keeps the Earth at the relatively comfortable temperatures that more life enjoys. However, while the levels of water vapor (which actually account for most of the greenhouse effect) have remained relatively stable, the amount of carbon dioxide and methane in the atmosphere has sky-rocketed, due largely to the burning of fossil fuels and the massive increase in the number of ruminant animals used for meat production.
