But carbon-14 is extremely rare, and to use it for identifying fossil fuels, scientists need to be able to measure it at concentrations as low as 1 part in 10 trillion.

That's the equivalent of a single grain of sand in 60 dump trucks full of the stuff.

Scientists at the National Institute of Standards and Technology (NIST) have developed a laboratory instrument that can measure how much of the carbon in many carbon-containing materials was derived from fossil fuels.

This will open the way for new methods in the biofuels and bioplastics industries, in scientific research, and environmental monitoring.

Such tests could also be used to verify that bioplastics, which sell for a premium, do not contain petroleum-derived compounds.

You then tune a laser to the exact wavelength that only heavy CO2 absorbs and shoot a burst of it into the cavity.

Scientists can calculate how long ago something died by measuring how much carbon-14 is in its remains.

That technique is called carbon dating, and scientists use it to date things like Neanderthal bones and ancient plant fibers.

Among other things, it will allow scientists to measure how much of the carbon dioxide (CO2) in the atmosphere came from burning fossil fuels, and to estimate fossil fuel emissions in an area as small as a city or as large as a continent.

This is possible because carbon atoms occur in heavy and light forms, or isotopes, and measuring the relative amounts of each can reveal the source of the carbon.
