World Took Step Towards Greener GDP in 2014; More Needed: PwC

Governments took a step towards greener economic growth in 2014 but will need to do far more to limit rising temperatures to a United Nations goal of two degrees Celsius (3.6 Fahrenheit), a study by accountancy firm PwC said on Monday.

World GDP rose by 3.2 percent in 2014, while carbon emissions rose by just 0.5 percent, it said.
