Air pollution and climate change are two important threats facing in our planet and are tightly
linked to carbonaceous components in the atmosphere. A better understanding of the …

We present 60 years of Δ 14 CO 2 measurements from Wellington, New Zealand (41° S,
175° E). The record has been extended and fully revised. New measurements have been …

Examining the contribution of fossil fuel CO 2 to the total CO 2 changes in the atmosphere is
of primary concern due to its alarming levels of fossil fuel emissions over the globe …

Independent estimates of fossil fuel CO2 (CO2ff) emissions are key to ensuring that
emission reductions and regulations are effective and provide needed transparency and …

COVID-19 lockdowns resulted in dramatic changes to fossil fuel CO2 emissions around the
world, most prominently in the transportation sector. Yet travel restrictions also hampered …

Fossil fuel carbon dioxide (FFCO2) is a major source of atmospheric greenhouse gases that
result in global climate change. Quantification of the atmospheric concentrations and …

We use the Kapuni Gas Treatment Plant to examine methodologies for atmospheric
monitoring of point source fossil fuel CO 2 (CO 2 ff) emissions. The Kapuni plant, located in …

Fossil fuel-derived CO 2 (Cff) emission patterns and their point sources across the Rio de
Janeiro megacity and state were estimated from a single regional-scale Δ 14 C distribution …

Quantifying fossil fuel CO 2 (CO 2ff) in the atmosphere provides a benchmark method to
monitor anthropogenic carbon emissions. Radiocarbon (14 C) in atmospheric CO 2ff has …

Radiocarbon dioxide (14 CO 2, reported in Δ 14 CO 2) can be used to determine the fossil
fuel CO 2 addition to the atmosphere, since fossil fuel CO 2 no longer contains any 14 C …
