Notes on data changes

Here we list notes explaining important emissions changes for the country.

• CRT data from BTR1 covering 2005, 2020, 2021 has been added. It replaces BUR3 data for 2005 and extends BUR3 for 2020-2021. Other country reported sources used are BUR3 for 2018 and NC4 for 2017.
  • The main change in the CR scenario is that energy CO2 emissions are higher after 2020 because of the CRT data. Waste CH4 and cement CO2 are lower for the latest years (also from new CRT data)
• For the TP scenario lower waste CHY4 emissions in EDGAR are the main source of change.
  • CO2 in 1.B.2 has been added to EDGAR data. This mostly affects cumulative emissions as 2023 emissions in the sector are low.

Changes by sector and gas

For each scenario and time frame the changes are displayed for all individual sectors and all individual gases. In the sector plot we use aggregate Kyoto GHGs in AR6GWP100. In the gas plot we usenational total emissions without LULUCF.
