IGU study finds that the switch to natural gas helps mega-cities dramatically improve air quality and reduce emissions of GHG and air pollutants – enhancing and saving lives. On the sidelines of the COP21 negotiations in Paris the IGU has released a major study that highlights the interconnection that exists between reducing greenhouse gas emissions and reducing emissions of other air pollutants. It presents case studies of efforts in four cities — New York, Istanbul, Toronto, and Beijing — that have tackled or are tackling the issue of improving urban air quality and where gas has featured as the main contributor to their efforts. These cities can provide lessons for other cities seeking to reduce the potentially severe health consequences of urban air pollution.
