HONG KONG: Environmentalists on Wednesday expressed disappointment at new clean-air targets for Hong Kong, as research showed pollution-related illnesses killed more than 3,000 residents a year. In the face of mounting public criticism and allegations that it is soft on polluting industry, the government on Tuesday announced its first revision to air quality objectives (AQOs) in 25 years. But the tighter standards will not be implemented until 2014 and fall well short of World Health Organisation guidelines.

As part of CAI-Asia's mission to promote better air quality and livable cities, CAI-Asia conducted an annual review of main events relevant to air quality, climate change and transport in Asia. The review, which started on 2008 and initially focused on sustainable transport, has now evolved to include air quality and climate events. It is an opportunity to look back and understand where Asia focused in the past year and foresee emerging trends in Asia in the coming years.

This briefing paper, prepared by Clean Energy Nepal and Clean Air Network Nepal, highlights the features, benefits and challenges of BRT system and the possibility to integrate trolleybus with BRT features in Kathmandu valley.

The massive rise in air pollution levels in 2011 was a major worry for the government. Attempts to bring down pollution levels will be its priority in the coming year, say senior government officials. To begin with, air pollution monitoring and forecasting systems will be set up across the city not only to indicate health impacts of air pollutants but also to help the government frame new policies to deal with the menace.

While Indian cities have grown manifold in the past several decades, and there is expectation that the pace of urbanization would accelerate in the future, problems of water supply, sewage disposal, municipal wastes, power supply, open landscaped spaces, air pollution, and public transport, have assumed stark proportions in many urban areas. These are linked, in turn to several causal factors, some obvious or proximate, such as inadequate and improper land-use planning, and others which lie at a deeper level.

Beijing authorities said Sunday they had met their target of “blue sky” days for 2011, amid growing public criticism that officials are underplaying the pollution problem in the Chinese capital.

The city had 274 days of “grade one or two” air quality compared with 252 days in 2010, according to a statement on the Beijing government’s official news portal.

“Beijing has seen an overall decline in the concentration of various pollutants in 2011,” said Zhuang Zhidong, the deputy director of the Beijing Municipal Environmental Protection Bureau.

If you have been coughing, wheezing, finding it difficult to breathe and overall feeling rather blue during this change of season, blame it on the low wind speed and high levels of particulate matter being recorded in the Capital.

Vehicle emission and fuel quality standards play a critical role in limiting the emissions from each vehicle and, together with other measures, in reducing the impact of continued vehicle growth on Asia’s air quality. In Asia’s cities, the average concentration of PM10 (particulate matter 10 microns or less in diameter) in the air is 90μg/m3, exceeding the World Health Organization air quality guideline of 20μg/m3 by almost 400%. As PM10 in the ambient air increases by 10μg/m3, the risk of early deaths in Asia goes up by 0.5% according to research done by the Health Effects Institute.

As the city celebrated Deepavali on Wednesday, few among those merrily bursting fire crackers would have realised that air pollution rose to unusually high levels, noise exceeded permissible limits and thick smog shrouded residential areas and roads.

Respirable suspended particulate matter (RSPM) touched 1423 microgram/cubic metre at Arumbakkam. The permissible limit is 100 microgram/cubic metre.

The pollution level during Diwali has been falling since last 10 years, claimed environment secretary of Delhi government Keshav Chandra on Thursday. Mr Chandra said that the positive results surfaced because of the chief minister’s appeal for better air quality during Diwali.
