CSE symposium, 20 November 2014; BAQ 2014 Conference, Colombo
Centre for Science and Environment organised a symposium on 20 November 2014 at the Better Air Quality conference held in Colombo during 19-21 November 2014
The symposium deliberated on how the Asian countries could deal with the health impact of particulate matter and black carbon that is a fraction of the particulate matter, implicated for enhancing warming impact. This emerging science has blurred the boundaries between the local and global impact of pollution. In the transport sector particularly, the dominant use of poor quality high sulphur diesel is aggravating both local toxic risks as well as climate risk because of high black carbon emissions. This multiple burden of risks demands active, cohesive and aggressive policy response across regions of the world to phase out dirty diesel and introduce clean diesel.
Cities of Asia now face this challenge of the balance – i.e. curb local air pollution to save lives, and at the same time, shrink carbon and energy imprints of growth and motorisation to save fuels and climate. It is disturbing to see the results of the global burden of disease that shows air pollution is still among the largest killer with disproportionately high impacts in Asia. Asian cities will have to be enabled to make quick transition to clean and efficient technology and mobility paradigm.
To achieve the objectives of climate and health co-benefits, it is important to deepen policy understanding of the challenges, policy action and opportunities in different regions of the world – Asia, Europe and the US. This symposium helped to draw lessons and accelerate global technology roadmap and fiscal strategy for climate and health co-benefit that will also benefit Asia.
Dieselisation is a serious health and climate concern that all regions of the world will have to address together. This requires deeper understanding of experience with diesel regulations and implementation in different regions to inform national action on diesel roadmap and air pollution control strategies.
Aggressive action on diesel can ensure health and climate co-benefits across regions.
