Airlines from China and India could face fines after refusing to disclose information on their carbon dioxide emission to the EU.

Brussels required airlines to report their emissions to individual EU member states and charge carriers for pollution when flying into the bloc. Ten Chinese and Indian airlines failed to provide the data by the middle of June.

This is considered as a serious sign of refusal to comply to Brussels’ aviation rules. The airlines – two from India and eight from China – may be banned from flying into the EU. Several countries attacked Brussels for its requirement, saying that it is using carbon emissions as a trading scheme.

Brussels said that carriers flying into the country had handed over carbon emission information, except for China and India. The bold move may set a “dangerous” example to other countries, analysts said. New Delhi voiced its opinion on the matter, saying that Brussels “had no power to enforce its laws on non-European carriers”.
