Short summary

This paper assesses the potential of atmospheric ¹⁴CO₂ observations and a global inversion system to solve for fossil fuel CO₂ (FFCO₂) emissions in Europe. The estimate of monthly emission budgets is largely improved in high emitting regions. The results are sensitive to the observation network and the prior uncertainty. Using a high-resolution transport model and a systematic evaluation of the uncertainty in current emission inventories should improve the potential to retrieve FFCO₂ emissions.
