Envoys at United Nations global warming talks are working on streamlining their negotiation process for the first time in at least six years, a step toward drafting a treaty by 2015 mandating more greenhouse-gas limits.

Delegates from more than 190 countries plan to close two parallel strands of talks and concentrate on one track, the biggest change to the process since 2007. The meeting, now in its fifth day in Doha, has avoided the rancor of the past three gatherings to focus on laying the groundwork for a deal limiting fossil-fuel emissions that would take effect by 2020.
