China has “banned” all airlines in the country from joining the European Union’s Emissions Trading Scheme (ETS) aimed at cutting carbon emissions.
The authorities have also barred the airlines from increasing their fares or adding new charges for the scheme.
The ban comes just weeks after the China Air Transport Association said its members did not support the ETS.
The scheme, implemented from 1 January, levies a charge on flights in EU airspace based on carbon emissions.
The move by the Chinese authorities is likely to complicate the issue as the EU will have to decide on what measures it will take from here on.
