Global south leading efforts to improve air quality while major polluters lag

Colombia and Mali rank highest in study of plans for cleaner air, while UAE, host of Cop28, among rich nations scoring poorly

Low- and middle-income countries (LMICs) are leading global efforts to improve air quality as part of national climate plans, according to a ranking that scores Colombia and Mali highest and puts the United Arab Emirates, which will host the Cop28 climate conference next month, among the worst.

Findings of a study by the Global Climate and Health Alliance published on Wednesday show that countries from the global south have the most ambitious strategies to address air pollution and its health impacts, while major polluters - such as the powerful G20 countries - are lacklustre in their commitments.
