The long-awaited draft said nations could take actions to slash greenhouse gas emissions, including reducing both consumption and production of fossil fuels by 2050, in line with what the science says must be done to avert the worst consequences of global warming. But it said nothing about deeply cutting fossil fuel use this decade, which scientists say is required to keep global warming at relatively safe levels. And the use of could makes action optional, analysts said.
The deadline for an agreement is Tuesday, and the talks are now expected to go into overtime as negotiators haggle over language. Under U.N. rules, all 198 nations must reach consensus on an agreement; any one nation can scuttle a deal.
