Technical Annual Status Report (Stage 2) for the CLRTAP Inventory Review: Synthesis and Assessment Country report
KEY CATEGORY ANALYSIS
Party: SK Submission year: 2026
Key categories analysis is becoming important in prioritising emission sources and identifying where inventory improvements can be most efficiently implemented. We have assessed the most important sources (the sources making up 80% of the national total) for your country, based on your latest submission. The key sources for the 2024, 2010 and 2005 emissions, including the corresponding percentages, are listed below. |
