Lawmakers in Prime Minister David Cameron's coalition this week plan to rebel against the government in favor of setting pollution targets earlier, a measure industry groups say will hurt the economy.
Some members of the ruling Conservative and Liberal Democrat parties plan to join with the Labour opposition in demanding the government set by April 1 a target for removing most carbon emissions from power generation by 2030. The government wants to postpone that decision until 2016. A vote on the legislation is due Tuesday in the House of Commons.
The rebels are concerned Britain risks delaying the investment needed to curb emissions blamed for global warming. Cameron, backed by some utilities and the Treasury, want to wait for the economy to recover before establishing a target.
