BANGKOK • Asia is a critical battlefield in the global fight to rein in air pollution, registering about five million premature deaths each year, delegates at a United Nations conference said yesterday, as they urged tougher enforcement of curbs.
The World Health Organisation (WHO) calls air pollution the greatest environmental risk to human health. About 90 per cent of related deaths take place in low-and middle-income countries, most of them in South-east Asia and the Pacific.
"There is a sense that if you're developing economically it doesn't mean that you have to live in a city where you can't breathe the air," Dr Dechen Tsering, the Asia-Pacific director of the UN Environment programme, said at the two-day event.
"There is also a growing sense that there are technologies, there is financing (to help)," said Dr Tsering, adding that the region was a key battleground in the fight.
Air pollution grew more than 5 per cent between 2008 and 2013 in more than two-thirds of South-east Asian cities, the WHO said in a report in 2016.
Children are "uniquely vulnerable", said Ms Karin Hulshof, East Asia and Pacific director for the UN children's agency Unicef.
She said about 300 million children worldwide live in areas where the air is toxic.
"What we are seeing, more and more, in cities like Ulaanbaatar, is hospitals full of children suffering from diseases related to air pollution," said Ms Hulshof, referring to a public health crisis in Mongolia's capital caused by toxic smog.
Emissions limits are simply not being enforced in Asia, however, said Mr Andreas Kock, managing director at Scheuch Asia, which develops and produces environmental cleaning technologies.
"Basically, they are not investing because the pressure is not there," said Kock, who called for efforts to spur industries in Asia to adopt pollution-reducing technology.
Major cities, such as Bangkok, need to build comprehensive public transport networks and push citizens to use them, Dr Tsering said, as well as environment-friendly vehicles, like bicycles.
That is the aim of Mobike, a bike-sharing service.
"In Bangkok, we operate in two locations and we hope to expand in a few months," said Mr Sam Nathapong, a representative of China-based Mobike.
