(Reuters) - Global carbon dioxide (CO2) emissions in 2011 rose 2.5 percent to 34 billion tonnes, a new record, Germany’s renewable energy institute said on Tuesday.
The IWR, which advises German ministries, cited recovered industrial activity after the end of the global economic crisis of recent years.
“If the current trend is sustained, worldwide CO2 emissions will go up by another 20 percent to over 40 billion tonnes by 2020,” IWR director Norbert Allnoch said.
China led the table of emitters in 2011 with 8.9 billion tonnes, up from 8.3 billion a year earlier. Its CO2 output was 50 percent more than the 6 billion tonnes in the United States.
