Methodology: IPCC Key Category Analysis - Approach 1
Level Assessment
Categories are sorted by their absolute emission level contribution. Categories are cumulated from largest to smallest. Those that together contribute to 95% of the total national emissions are identified as key categories. Per 2006 IPCC Guidelines, Volume 1, Chapter 4.
Trend Assessment
Evaluates the trend in emissions between the base year (1990) and the latest year (2022). Categories with the largest absolute contribution to the overall trend are identified as key categories for trend. This helps prioritize categories where emissions are changing rapidly.
