Accelerating growth in the transport sector, a booming construction industry, and a growing industrial sector are responsible for worsening air pollution in Indian cities.
More and more cities around the world are developing dedicated Climate Change Action Plans to reduce Greenhouse Gas (GHG) emissions and improve the local air quality for their inhabitants. The transport sector usually plays a crucial role in any such strategy.
This, the first systematic study, quantifies the health effects of air quality regulations in Delhi, which adopted radical measures to improve air quality, including, for example, the conversion of all commercial vehicles to compressed natural gas (CNG), and the closure of polluting industries in residential areas from 2000 to 2002.
Building an effective air quality management system (AQMS) requires a process of continual improvement, and the source apportionment techniques described in this report can contribute in a cost effective manner to improving existing systems or even as the first step to begin an AQMS.
As part of CAI-Asia mission to promote better air quality and livable cities, CAI-Asia conducted an annual review of the main events relevant to air quality, climate change and transport in Asia. This review, which started on 2008 and initially focused on sustainable transport, has now expanded to include air quality and climate events.
In a number of cities in India, air pollution is a growing problem, not only limited to the megacities, but also spreading through the tier II and tier III cities. Given a diverse mix of sources in these cities, with megacities dominated with transport sector and the secondary
This new synthesis report provides outcome of the Air Quality Monitoring, Emission Inventory and Source Apportionment Study carried out in the cities of Bangalore, Chennai, Delhi, Kanpur, Mumbai and Pune. The primary focus of the study was on respirable particulate matter (PM10), although it also deals with other pollutants like NOx, SO2, Ozone (O3), PM2.5, etc.
When governments develop policies, a major limiting factor is availability of sufficient information. Information often does not reach policy makers at the right time or in the form in which it is needed.
Air pollution levels in the megacities of Asia show a stabilizing trend but still exceed World Health Organization guidelines. Studies also show poor air quality, not only in the megacities of Asia, but also in smaller cities.
