Characterization of German SF₆ Emissions.

ABSTRACT: Sulfur hexafluoride (SF₆) is a highly potent greenhouse gas with a Global Warming Potential (GWP) of 24,700 over 100 years and is globally mainly used as an electrical insulator in switchgear. Several measurement networks have tracked SF₆ for many years and their European data reveal significant emissions in southern Germany. This study focuses on German SF₆ emissions (2020-2023), using atmospheric measurements from 22 European sites, offering high spatial and temporal resolution for robust emission assessments. While German UNFCCC inventory bottom-up emission estimates report a major source of SF₆ through the disposal of soundproof windows, the spatial distribution of German SF₆ emissions derived on top-down inversion techniques (InTE
