Government officials from countries opposed to the European Union's carbon emissions tax will meet in early February to discuss taking joint retaliatory action against the scheme, according to reports.
It follows an initial meeting in New Delhi last September, during which 21 nations, including India, Russia and the US, signed a declaration opposing the EU's decision to bring aviation into its Emissions Trading System (EU ETS) from 1 January.
Next month's meeting is expected to take place in either Delhi or Moscow.
It is thought one of the retaliatory measures up for discussion could involve placing restrictions on inbound flights from European airlines.
Commenting on the reports of a meeting in February, Steve Lott, spokesperson for Airlines for America (A4A), which unsuccessfully challenged the EU ETS in the European Court of Justice last year, said: ""We support governments around the world getting together to further consider and plan next steps of opposition.
"In recent months, the US government and dozens of others around the world have increased pressure on the EU to come back to the table to consider a global sectoral approach."
The European Commission declined to comment.
