It can be biologically decomposed using the hydrolase enzyme alkylhalidase by the reaction: In the "Enter the Matrix" video game, the player can find a "Chloro-Bromo Methane Gun", which is used as a fire extinguisher.

After seven years of negotiations, in October 2016 at the 28th Meeting of the Parties to the Montreal Protocol in Kigali, the Parties to the Montreal Protocol adopted the Kigali Amendment whereby the Parties agreed to phasedown HFCs under the Montreal Protocol.

A group of developing countries including China, Brazil and South Africa are mandated to reduce
