Air pollution is one of the largest threats to health across the world and although access to clean air is a fundamental human right, air pollution accounts for about seven million deaths around the world yearly. Air pollution contributed to 30 percent of all pneumonia deaths in 2019; with 59 percent contamination from household sources and 44 percent from outdoor sources.
Nigeria currently ranks 18th in the list of most polluted countries in the world with an average of 34 micrograms per cubic meter of particulate matter concentration.
