The Guardian cites a new report from Price Waterhouse Cooper Consulting saying the world is on track for an average global temperature increase of 6 degrees C (10.8 F) by the end of the century at current rates of carbon emission, with catastrophic implications for human life.
New research by consultancy giant PwC finds an unprecedented 5.1 per cent annual cut in global emissions per unit of GDP, known as carbon intensity, is needed through to 2050 if the world is to avoid the worst effects of climate change and meet an internationally agreed target of limiting average temperature increases to just two degrees above pre-industrial levels.
Such deep reductions in carbon intensity would be over six times greater than the 0.8 per cent average annual cuts achieved since 2000.
The report also confirms that greatest rises in greenhouse gas emissions came from the emerging E7 economies of China, India, Brazil, Mexico, Russia, Indonesia and Turkey, whose cumulative 7.4 per cent annual increase in emissions swamped record levels of reductions in the UK, France, and Germany.
PwC warns sustained economic growth in these countries could “lock in” high carbon assets that will make it significantly harder for them to decarbonise over the coming decades, a point likely to be raised at the UN-backed Doha Climate Summit when it kicks off later this month.
It also warns that industrialised countries must accelerate their partially successful efforts to reduce carbon emissions.
