Most US shipowners moved from halon to CO2 for their engine room protection for new ships. Existing ships with halon systems installed continue to use recycled/reclaimed halon to recharge the systems which are discharged, or which need to be topped off.

Inert gas systems, like nitrogen or nitrogen/argon systems require large cylinders under high pressure to supply the gas.

CO2 and HFC-125 systems were supposed to replace Halon but they may be on the way out as well. The Kyoto Protocol was adopted without the participation of the United States on December 10, 1997. It committed the countries which signed to reductions in the release of Global Warming Gases which included CO2 and hydrofluorocarbons (HFCs).
