Measuring power plant CO2 emissions

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
