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. The main highlights for 2011 are: Increasing public demand for improved air quality monitoring and reporting; Transition from science to policy action regarding black carbon and short-lived climate forcers (SLCF); Increased awareness on green freight and logistics; Successes on clean fuels and vehicles, particularly in Vietnam and Sri Lanka; Improved understanding of walkability issues in Asia; and Asian cities trying out a mix of transport demand management measures to address congestion, pollution.
