A slow start to reducing global greenhouse gas emissions means countries will have to work harder than ever to avoid castrophic global warming, said a recent report from PwC.
In its annual Low Carbon Economy Index, the global business consultancy found that the carbon produced for each unit of production - known as carbon intensity - would have to shift from its current annual reduction rate of 0.8 per cent to over 5 per cent to meet global targets.
PwC noted that current pledges to reduce emissions were not enough to limit global warming to within two degrees Celcius, which is the allowable window agreed to at climate talks in 2010.
Nations meet in Qatar at the end of November to discuss ways to speed up progress.
