Fluorinated Greenhouse Gases in Sweden : Review of Methodology and Estimated Emissions Reported to the UNFCCC and the EU monitoring Mechanism

• Sweden reports emissions of fluorinated greenhouse gases (F-gases) annually to the UNFCCC and the EU Monitoring Mechanism. Emissions of F-gases amounted to about 2 per cent of national total emissions 2009 and show an increasing trend since 1990. National and international regulations have entered into force in order to reduce emissions of F-gases. The national system for estimating emission of F-gases is based on national statistics from the Swedish Chemicals Agency and additional information sources. Due to the projected reduction of emissions in the near future, there has been an increasing focus on the reliability of the monitoring of such changes over time, especially for certain sub-categories such as F-gases from mobile air-conditioning equipment.The aim of this study has been to improve the quality of the collection and emission estimation system in Sweden for F-gases reported to the UNFCCC and the EU Monitoring Mechanism and especially in order to enable better annual follow-up of changes in chemicals flows and emissions of F-gases e.g. due to increased amounts of HFC recovered and the enforced national and international legislations.The national statistics available and the most important additional information sources and emission factors have been reviewed in this study. The results of this study show that the national statistics from the Swedish Chemicals Agency and the additional information sources continues to be a good foundation for the Swedish emission inventory reporting.In this study no major adjustments are recommended for the collection and emission estimation system, but there are some suggestions on modifications of emission factors and model macros. In addition, this study includes several recommendations for future improvements on emission inventory quality control checks as well as on national data management procedures.
