Notes on data changes

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

• CRT data has been included. It replaces the official inventory used in v2.6.
  • Changes in the CR time-series are small and come from updated third party data (EDGAR, FAO) which is used to extrapolate the country reported data.
• Changes in the TP time-series come from updated EDGAR data in several sectors.
  • NOTE: EDGAR HFC emissions are much lower than country reported emissions. They are however, perfectly in line with country reported HFC emissions excluding the “Unspecified mix of HFCs” reported in the CRT data. This means that EDGAR is likely ignoring the HFC gas mix which makes up up to 2/3 of Japan’s HFC emissions.

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.
