Simulating the integrated summertime Δ¹⁴CO₂ signature from anthropogenic emissions over Western Europe [PDF]

Atmospheric Chemistry and Physics, 2014
Radiocarbon dioxide (14CO2, reported in Δ14CO2) can be used to determine the fossil fuel CO2 addition to the atmosphere, since fossil fuel CO2 no longer contains any 14C.

Measured Canadian oil sands CO2 emissions are higher than estimates made using internationally recommended methods

Nature Communications, 2019
Evaluating GHG emissions reported to inventories for the oil and gas (O&G) sector is important for countries with resource-based economies. Here the authors provide a top-down assessment of GHG emissions from the Canadian oil sands and find previous ...
