Figures released by the International Energy Agency (IEA) show that energy-related carbon emissions reached a record high last year.
The previous record in 2008 was eclipsed by 5% last year, after a dip due to the financial crisis in 2009.
Whilst emissions have grown in developed countries it is India and China who account for the bulk of the rise.
The IEA say that the increase will raise doubts as to whether or not planned curbs on greenhouse emissions can be achieved.
The IEA's Fatih Birol said the finding were "another wake-up call".
"The world has edged incredibly close to the level of emissions that should not be reached until 2020 if the 2C target is to be attained," he added.
"Unless bold and decisive decisions are made very soon, it will be extremely challenging to succeed in achieving this global goal agreed in Cancun."
