In 2010, emissions reached an all-time high of 9.1 billion tons of carbon, compared with 8.6 billion tons in 2009. The downturn was also followed by milestone carbon dioxide emissions from the developing world's emerging economies. In developing countries, consumption-based emissions, or those emissions associated with the consumption of goods and services, increased 6.1 percent over 2009 and 2010.
As a result, 2009 marked the first time that developing countries had higher consumption-based emissions than developed countries.
"Previously, developed countries released more carbon dioxide, but that's no longer true due to emerging economies in developing countries, such as China and India," said Tom Boden of ORNL's CDIAC. "This trend will likely continue in the future based on current developments."
Authors of the paper, "Rapid growth in CO2 emissions after the 2008-2009 global financial crisis" published in Nature Climate Change, credit three major factors for the rapid carbon dioxide rebound.
"The impact of the 2008-2009 Global Financial Crisis (GFC) on emissions has been short-lived due to strong emissions growth in emerging economies, a return to emission growth in developed economies, and an increase in the fossil fuel intensity of the world economy," said the authors of the paper.
So far, the GFC has not contributed to a long-term decrease in global carbon emissions, as has been the case in the past. For example, the oil crises in 1973 and 1979 caused persistent price shocks and structural changes in energy production and consumption that led to a reduction in the global reliance on oil and an increase in the reliance on natural gas, which resulted in a drop in emissions.
"The GFC was an opportunity to move the global economy away from a high emissions trajectory," the authors say. "Our results provide no indication of this happening and indicate that the GFC has been quite different from previous global crises."
Boden cites two reasons for this uncharacteristic rebound.
"The GFC did not impact major developing countries, such as China and India, like it did the United States and the European nations," Boden said. "Also, some of the negative effects on sectors impacted during the GFC, such as the transportation sector involved in international trade, are over or at least have subsided."
This work is a collaborative effort of the Global Carbon Project, a joint project of the Earth System Science Partnerships, to provide regular analyses of the main global carbon sources and sinks. In addition to Boden of ORNL, authors of the paper include Glen Peters of the Center for International Climate and Environmental Research; former ORNL environmental sciences division staff Gregg Marland, now of Appalachian State University; Corinne Le Quere of the University of East Anglia; and Joseph Canadell and Michael Raupach of Marine and Atmospheric Research in Australia.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
