Eine neue Studie hat ergeben, dass die Emissionen von fünf ozonabbauenden Chemikalien, deren Herstellung für die meisten Verwendungszwecke im Rahmen des Montreal-Protokolls verboten wurde, zwischen 2010 und 2020 rapide angestiegen sind. Die Emissionen dieser fünf Fluorchlorkohlenwasserstoffe (FCKW) entstehen zum Teil durch Leckagen bei der Herstellung von ozonfreundlichen Ersatzstoffen. Obwohl derartige Emissionen von Neben- bzw. Zwischenprodukten im Rahmen des Montreal-Protokolls erlaubt sind, stehen sie im Widerspruch zu dessen Zielen – und die beobachteten Zunahmen geben Anlass zur Sorge.
