European Union governments are poised for a fight over the the size of a fund designed to cushion some consumers from costs in a new carbon market, with France to propose limiting its size as part of a deal on an ambitious climate plan for 2030.

France, the current holder of the rotating EU presidency, aims for an agreement on Tuesday among national governments on how to enact the 55% emissions-reduction target for this decade.

France suggested a new emissions program for buildings and transport be delayed by one year and a fund to alleviate the impact of the new market be cut to €59 billion ($62 billion) from €72 billion proposed by the European Commission, according to EU diplomats with knowledge of preparatory talks before the June 28 ministerial meeting.
