An important point of contention at the Paris climate talks — whether to regularly review nations’ pledges on emissions cuts, inthe hopes of stimulating further reductions — may be close to being resolved. U.N. climate chief Christiana Figueres says there is a growing consensus that emissions-reduction pledges should be reviewed every five years, a stance supported by the U.S., China, and the European Union. Other nations, such as India, have been reluctant to commit to such reviews. Figueres, French Foreign Minister Laurent Fabius, and other top officials at the Paris talks are urging delegates to begin resolving issues such as emissions-pledge reviews, as the 50-page draft climate treaty now contains four to five alternative versions of disputed points. Fabius has given negotiators until Thursday night to deliver a streamlined draft and has set a deadline of noon Saturday to come up with a close-to-final draft.
