Clean air is a vital natural resource on which all life depends and is something that we all need for good health and well-being. Sadly, the rapid growth of cities around the world is causing ever-worsening air pollution. The World Health Organization (WHO) has long identified urban air pollution as a critical public health problem and it is estimated to cause approximately 2 million premature deaths worldwide per year. With cleaner air, we can have better public health and a better quality of life. Fresh air will also contribute to a cleaner environment which is an asset in attracting potential investors, talents and tourists. Many developing countries and emerging economies have therefore included air pollution into their list of priority issues to be tackled.
