Review Stage 2: Synthesis and Assessment Country report
KEY SOURCE ANALYSIS
Party: IE Submission year: 2022
Key categories analysis is increasingly important in order to prioritize emission sources and identify where the implementation of improvements is most effective. 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 2020, 2010 and 2005 emissions, including the corresponding percentages, are listed below. |
