This deliverable is primarily to present the factsheets of GHG emissions (including the three main gases CO2, CH4 and N2O) for the current EU27 region. Under the context of the changing Regulation for GHG monitoring, the factsheet provides some scientific insights for the challenging switch to the post-2020 reporting regime (cfr. Regulation 1999 of 2018) that for the first time includes in the climate targets, next to the GHG emissions of the Emission Trading System (ETS) and Effort Sharing Decision (ESD) sectors, also the LULUCF GHG estimates. The information makes use of the bottom-up reported inventories as well as the top-down observation-based budget with time series from 1990 to 2018, based on the published GHG data for EU (cfr. EEA Data GHG reviewer) as well as the scientific budgets published as VERIFY deliverables (cfr. Petrescu et al. ESSDD, 17 and 18 Dec. 2020a,b). The factsheet presents the GHG total (including LULUCF) composed of CO2, CH4 and N2O, with the latter converted into CO2eq using the AR4 GWP100 metrics. Uncertainties are known to be large for CO2 (LULUCF), CH4 and N2O. For CH4 and N2O, observation-based scientific results provide insights on the uncertainty range. Improvement potentials are further indicated by addressing the uncertainties for the LULUCF estimates and by proposing a higher temporal resolution for (near) real time reporting.
