With the recent accession of three new municipalities – Podgorica (Montenegro), Korça and Durrës (Albania), the Clean Air Regions Initiative (CARI) is dynamically growing, with the number of participants currently standing at thirteen. With the launch of the CARI at the Just Transition Forum on 30 June 2021, ambitious municipalities have set the goal to undertake voluntary measures to reduce air pollution at local level.
Podgorica, being the first capital to join CARI, brings an important contribution to the further development of the initiative. The municipalities of Korça and Durrës, the first municipalities from Albania to join CARI, are both important touristic destinations and have a clear ambition to maintain their good air quality status, especially with a focus on transport-related emissions.
 The pioneer signatories of the Clean Air Regions Initiative are the municipalities of Banovići, Kakanj, Lukavac, Maglaj and Tuzla from Bosnia and Herzegovina, Pljevlja from Montenegro, Bitola from North Macedonia and Niš and Novi Sad from Serbia. The municipality of Živinice from Bosnia and Herzegovina joined the initiative in September 2021.
