This is the best summary I could come up with:

All but one country in the top 15 spots in the GCHA ranking are from LMICs, including Ivory Coast, Nigeria, Pakistan, Ghana, Albania, Bangladesh, Cambodia, El Salvador, Honduras and Sierra Leone.

Jess Beagley, GCHA’s policy lead, said: “It is telling that the countries seeking to take the greatest action on air pollution are often those bearing the brunt of the impacts.”

In contrast, G20 countries score poorly – Canada and China are the best performers among these nations, while Australia, Brazil, the EU, India and the UAE are the lowest scorers.

“As major global polluters, it is crucial for G20 countries to embed air-quality considerations into their [nationally determined contributions], yet no G20 government even scores half-marks – indicative of lack of recognition of the links between climate and air quality, or ambition to take action.”

The GCHA ranking compares 169 countries and the EU on their progress towards integrating air-quality considerations into their national climate action plans.

It is aimed at assessing “the extent to which governments’ national climate commitments recognise and contribute to ensuring healthy air for communities around the world”.
