This study updates the state-of-the-art scientific overview of CH₄ and N₂O emissions in the EU27 and UK in Petrescu et al. (2021a). Yearly updates are needed to improve the different respective approaches and to inform on the development of formal verification systems. Read more.

Nations need to track their emissions and removals of CO₂ over time to determine whether emission reduction actions are having the intended effect of reducing national CO₂ emissions. These national CO₂ emissions include fossil fuel emissions as well as emissions and removals of CO₂ from the terrestrial biosphere (terrestrial carbon stocks), which are impacted by deforestation (CO₂ emissions) and reforestation or improved land stewardship (CO₂ removals). In this study, observed variations in atmospheric CO₂ concentrations are used to infer "top-down" net emissions and removals of CO₂ for more than 100 countries across the world during 2015–2020.
