SARAJEVO (Reuters) - Most Western Balkan countries have failed to fulfil the first requirement to meet European Union industrial emissions standards despite commitments governments made in 2005, environmental campaigners warned on Tuesday.

Total sulphur dioxide (SO2) emissions in EU aspirants Serbia, Bosnia, North Macedonia and Kosovo in 2018 were six times higher than the 98,696 tonne ceiling set by the bloc, according to a report to be presented to the European Parliament by central and eastern European advocacy group CEE Bankwatch Network.
