Carbon dioxide emissions rebound quickly after global financial crisis

06.12.2011
The sharp decrease in global carbon dioxide emissions attributed to the worldwide financial crisis in 2009 quickly rebounded in 2010, according to research supported by the Carbon Dioxide Information Analysis Center at the Department of Energy's Oak Ridge National Laboratory.

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. CDIAC is supported by the U.S. DOE Office of Science.

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
