Stufenweise Reduzierung der fluorierten Treibhausgase (F-Gas-Verordnung)

  • Sowohl nationale als auch internationale Vorschriften stellen einen der wichtigsten Mechanismen zum Fordern von Investitionen in neue Technologien dar. Abbildung 4 gibt einen Uberblick uber die Beschrankungen und Verbote, die bereits fur die Branche gelten und uber einige mogliche Masnahmen fur die Zukunft (siehe auch den Abschnitt uber Normen und Gesetze spater in diesem Dokument). Die Umsetzung einiger Richtlinien ist freiwillig, bei anderen ist sie jedoch vorgeschrieben (rotes Dreieck). Alle zielen jedoch darauf ab, innerhalb des Markts Beschrankungen zu erlassen. Neben der Beeinflussung der Marktentwicklung ist auch die Verfugbarkeit von nachhaltigen Losungen (grunes Dreieck) immer wieder Anlass fur Bedenken. Wenn neue Vorschriften entworfen werden, sollen sie diese Parameter bereits berucksichtigen sowie sinnvolle und erfolgversprechende Prognosen stellen. Es gibt aber auch immer zahlreiche Herausforderungen, die Branchenfuhrer und Gesetzgeber erst auf dem Weg losen konnen. Anhang 1 liefert eine detaillierte Ubersicht uber die wichtigsten Vorschriften, einschlieslich des Montrealer Protokolls, der europaischen F-Gas-Verordnung und der US-amerikanischen SNAP-Richtlinie.

    Die Verwendung von HFCKW, vor allem R22, wurde innerhalb der EU bereits verboten. Auch in den USA und anderen Industrielandern ist das Verwendungsverbot nahezu umgesetzt. In Entwicklungslandern gelten seit 2015 ebenfalls Gesetze fur das schrittweise Verbot von HFCKW. Bis 2030 soll die Verwendung vollstandig verboten sein. Es darf nicht vernachlassigt werden, dass HFCKW wie R22 in vielen verschiedenen Anwendungen zum Einsatz kommen. Ihr Verbot stellt somit eine Herausforderung dar, da sie nicht durch ein einziges Kaltemittel mit geringem Treibhauspotenzial ersetzt werden konnen (Tabelle 2 in Anhang 1 zeigt den Reduktionsplan fur HFCKW).
