Radioactive bookkeeping of carbon emissions

A new sampling method uses carbon-14 to single out which carbon dioxide molecules in the atmosphere derive from fossil fuels. The method could help track emissions goals for climate mitigation.

New atmospheric radiocarbon measurements pull back the veil on fossil fuels

Researchers from NOAA and CU Boulder have devised a breakthrough method for determining emissions of carbon dioxide from fossil fuel combustion. In a paper published in the Proceedings of the National Academy of Sciences, the researchers report the first-ever national estimate of fossil-fuel derived carbon dioxide emissions obtained by observing carbon dioxide and its naturally occurring radioisotope, carbon-14, from air samples collected by the NOAA Global Greenhouse Gas Reference Network. This new method is expected to provide a more accurate look at changes in fossil fuel emissions as the economy begins its recovery amid the COVID-19 pandemic. In addition, the method will be particularly robust at identifying year-to-year emissions trends, allowing governments to independently assess their progress toward meeting the Paris Climate Agreement goals.

Ocean uptake of CO2 could drop as we cut carbon emissions

In recent decades, the oceans have been soaking up greater and greater amounts of carbon dioxide each year. We can’t count on that trend to continue forever, says a new study that includes Nikki Lovenduski.

Breakthrough helps scientists see CO2 from fossil fuels

Scientists have been using carbon-dating techniques for years to measure the age of Earth's archaeological treasures. Now they've found a way to use it to identify sources of man-made carbon dioxide emissions in the atmosphere. The research, underway in NOAA laboratories and the University of Colorado, Boulder, since 2003, might help nations and states reduce CO2 emissions from major sources in the fossil fuel and cement industries.
