Short summary
We examine the utility of tree ring 14C archives for detecting long-term changes in fossil CO2 emissions from a point source using six years of observations from two trees near the Kapuni Gas Treatment Plant in New Zealand. Pairing these observations with an atmospheric transport model, we quantify the minimum amount of change in annual emissions that it would be possible to detect in new samples representing averages over one, two, and four years.
