Researchers report that fossil fuel carbon dioxide (CO2) emissions from individual power plants can be quantified over time by measuring the radiocarbon content of atmospheric CO2 absorbed by either fast-growing plants or a sodium hydroxide solution located near the point sources, findings that reduce observational uncertainties to less than 10%, an improvement over the current 20% figure, and that allow for independent assessment of emissions instead of self-reporting by power plants. - Read at PNAS.org
