The world’s major economies are falling short of the actions they agreed to in 2009 to limit global warming to 2°C/3.6°F, according to management consultants PricewaterhouseCoopers. “The gap between what we are doing and what we need to do has again grown, for the sixth year running,” states PWC’s Low Carbon Economy Index, subtitled Two Degrees of Separation: Ambition and Reality. West says countries must cut their carbon intensity by more than five times last year’s rate to reach the 2009 target, to which they agreed at the Copenhagen climate summit. “Overall, PricewaterhouseCoopers paints a bleak picture of a world that’s rapidly running out of time,” he writes. “G20 nations, for example, will need to cut their annual energy-related emissions by one-third by 2030, and by just over half by 2050.”
