The EU said on Tuesday that Chinese and Indian commercial airlines have broken EU law requiring them to offset their carbon emissions. Ten Chinese and Indian airlines have broken the law whereas all other international carriers flying to or from Europe have complied, the European Union’s climate chief said. The EU law demanding all airlines participate in the EU’s Emissions Trading Scheme (ETS) has prompted outcry and threats of a trade war. But only eight Chinese and two Indian airlines have delivered on threats not to comply, while more than 1,200 airlines have met the EU’s requirements. EU climate commissioner Connie Hedegaard said the Indian and Chinese airlines were given until mid-June to report back their data.
