BRUSSELS: EU countries will seek Thursday to settle on an emissions-cutting plan to bring to a key UN conference in Brazil, as divisions on the bloc’s green agenda threaten its global leadership on climate. Environment ministers for the 27-nation bloc are gathering in Brussels with the clock ticking down on a United Nations deadline to produce plans to fight global warming for 2035.
