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 Celsius this century, a report released by PwC on Monday (5 November) showed.
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.
Carbon intensity will have to be cut by over 5% a year to achieve that goal, the study said. That compares with an annual rate of 0.8% from 2000 to 2011.
“Because of this slow start, global carbon intensity now needs to be cut by an average of 5.1% a year from now to 2050. This rate of reduction has not been achieved in any of the past 50 years,” it added.
