Unprecedented world carbon emissions cuts needed by 2050: PwC
The world will have to cut the rate of carbon emissions by an unprecedented rate to 2050 to stop global temperatures from rising more than 2 degrees this century, a report released by PwC on Monday showed.
PwC's annual Low Carbon Economy Index report examined the progress of developed and emerging economies towards reducing their carbon intensity, or their emissions per unit of gross domestic product.
Global temperatures have already risen by about 0.8 degrees Celsius above pre-industrial times. Almost 200 nations agreed in 2010 at United Nations climate talks to limit the rise to below 2 degrees C (3.6 Fahrenheit) to avoid dangerous impacts from climate change.
