2010 sees new record for greenhouse gas emissions
May 31st, 2011 by Jim JustThink the world is making any progress in tackling global warming? Think again: 2010 set a record high for greenhouse gas emissions.
Energy-related carbon-dioxide (CO2) emissions in 2010 were the highest in history, according to the latest estimates by the International Energy Agency (IEA).
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.
44% of the estimated CO2 emissions in 2010 came from coal, 36% from oil, and 20% from natural gas.
The IEA’s 2010 World Energy Outlook set out the 450 Scenario, an energy pathway supposedly consistent with achieving the goal of limiting average global temperature increase to 2°C. The IEA believes this pathway can be achieved if global energy-related emissions in 2020 are not be greater than 32 Gt. Achieving this would require that over the next ten years, emissions would have to rise less in total than they did between 2009 and 2010.
Of course, 450 ppm CO2 is much too high to avoid catastrophic consequences.
The conclusion that limiting CO2-equivalent to 450 ppm will succeed in limiting temperature increase to 2°C is based on the assumption that no feedback loops will kick in, an assumption that is already proving unfounded – for example, Arctic amplification is already kicking in and thawing permafrost will further accelerate global warming.
If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm. To be safe, we’ll likely have to get back to pre-industrial levels of 280 ppm, and rather quickly.
So how are we doing?
393 and counting.
Dr Fatih Birol, Chief Economist at the IEA, isn’t sounding optimistic.
Our latest estimates are another wake-up call. 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.
The IEA sees the challenge as squaring the circle: “improving and maintaining quality of life for people in all countries while limiting CO2 emissions.” The phrase “improving and maintaining quality of life” translates as business as usual: continued economic growth, growth that depends on increased energy consumption and results in the greenhouse gas emissions which are threatening to destroy Earth as we know it. More of what got us into this mess is not going to get us out.



















Under this scenario, people in the U.S. would expect to be twice as wealthy in 2050 as in 2005.
