CO2 emissions reach a record high in 2010; 80% of projected
2020 emissions from the power sector are already locked
Paris, May 30, 2011 - Energy-related
carbon-dioxide (CO2) emissions in 2010 were the highest in history,
according to the latest estimates by the International Energy Agency
After a dip in 2009 caused by the global financial crisis,
emissions are estimated to have climbed to a record 30.6 Gigatonnes
(Gt), a 5% jump from the previous record year in 2008, when levels
reached 29.3 Gt.
In addition, the IEA has estimated that 80% of projected
emissions from the power sector in 2020 are already locked in, as
they will come from power plants that are currently in place or
under construction today.
"This significant increase in CO2 emissions and the locking in of
future emissions due to infrastructure investments represent a
serious setback to our hopes of limiting the global rise in
temperature to no more than 2ºC," said Dr Fatih Birol, Chief
Economist at the IEA who oversees the annual World Energy
Outlook, the Agency's flagship publication.
Global leaders agreed a target of limiting temperature increase
to 2°C at the UN climate change talks in Cancun in 2010. For this
goal to be achieved, the long-term concentration of greenhouse
gases in the atmosphere must be limited to around 450 parts per
million of CO2-equivalent, only a 5% increase compared to an
estimated 430 parts per million in 2000.
The IEA's 2010 World Energy Outlook set out the 450
Scenario, an energy pathway consistent with achieving this goal,
based on the emissions targets countries have agreed to reach by
2020. For this pathway to be achieved, global energy-related
emissions in 2020 must not be greater than 32 Gt.This means that
over the next ten years, emissions must rise less in total than
they did between 2009 and 2010.
"Our latest estimates are another wake-up call," said Dr Birol.
"The world has edged incredibly close to the level of emissions
that should not be reached until 2020 if the 2ºC target is to be
attained. Given the shrinking room for manœuvre in 2020, unless
bold and decisive decisions are made very soon, it will be
extremely challenging to succeed in achieving this global goal
agreed in Cancun."
In terms of fuels, 44% of the estimated CO2 emissions in 2010
came from coal, 36% from oil, and 20% from natural gas.
The challenge of improving and maintaining quality of life for
people in all countries while limiting CO2 emissions has never been
While the IEA estimates that 40% of global emissions came from
OECD countries in 2010, these countries only accounted for 25% of
emissions growth compared to 2009. Non-OECD countries - led by
China and India - saw much stronger increases in emissions as their
economic growth accelerated.
However, on a per capita basis, OECD countries collectively emitted
10 tonnes, compared with 5.8 tonnes for China, and 1.5 tonnes in
