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. It is an opportunity to look back and understand where Asia focused in the past year and foresee the emerging trends in Asia in the coming years.
