The Process of Developing AQMx curated Guidance Air pollution is an issue that affects us all, with 99% of the world’s population breathing polluted air that contributes to millions of premature deaths and respiratory disease each year. Air pollution also significantly impacts crop yields, impacts warming, and can have harmful effects on biodiversity through habitat degradation and increased ozone pollution.Access to a clean, healthy, and sustainable environment is a human right, and with fewer than 2% of global development funding going towards cleaner air, it’s clear that more must be done to address harmful air pollution. The cost of inaction is too high. Air pollution knows no border, and tackling this challenge cannot be done in silos; it requires countries around the world to cooperate and work together to implement strong air quality monitoring and implement tried and tested methods that help cut pollution, creating cleaner communities for us all.
