PARIS (AP) - France’s parliament passed a sweeping law Thursday overhauling environmental standards and setting tough emissions targets, sending a signal to other major polluting nations ahead of global climate talks.

Legislators in both houses of French parliament approved the measure by a comfortable margin, with the majority conservatives and opposition Socialists supporting it. Green Party lawmakers and the Communists opposed it, saying it doesn’t go far enough.

The law says France should reduce its carbon emissions fourfold by 2050 and increase renewable energy sources to 23 percent of total energy production, about double current levels.

It will affect everything from toll booths to drafty windows. It sets targets for energy efficiency in new and renovated homes, for greener agriculture and waste management. It favors new high-speed trains and river traffic over road construction. It puts in place a system to monitor worker health and pollution.

The law stemmed from months of negotiations among environmental activists, farmers, industry officials and bureaucrats in 2007 to work out what President Nicolas Sarkozy called an environmental "New Deal" for France.

The talks were part of Sarkozy’s bid to catch France up to its greener neighbors and set an example to other nations.
