# The World Health Organisation is calling for urgent global action to tackle, what it says is the greatest environmental health risk, air pollution. Data show that 99-percent of the global population breathes air that exceeds WHO guideline limits and contains high levels of pollutants, with low- and middle-income countries suffering from the highest exposures. Air pollution causes around seven-million premature deaths each year from chronic respiratory diseases and lung cancer. WHO says policies to reduce air pollution offer a win-win strategy for both climate and health.
