Europe lags behind US in new plans to tackle CO2 emissions from planes

Europe's proposals for a landmark international fuel efficiency standard for aircraft would save considerably less carbon emissions than those put forward by the US

Europe is calling for a considerably less ambitious carbon emissions standard for airplanes than the US in a new global push to reduce aviation's contribution to climate change, the Guardian has learned.

The standard would mark a turning point for efforts to regulate fast-growing emissions from airplanes, which are not covered by December's much-hailed Paris climate agreement.
