OPINION: REFRIGERANTS
Black Market Refrigerants pose a major shipping risk

However, the main reason Honeywell, Linde and Dupont, which containers exploded, killing three they are highly toxic, and in the case of these refrigerants continue to circulate have taken legal action to crack down port workers.

Whether or not a global ban on dis- posable cylinders will come into force anytime soon is unclear. In 2007, the
European Union (EU) banned dispos- able refrigerant cylinders in the EU and on EU ? agged vessels. Similar bans are also in place in Canada, India and Aus- tralia. However, disposable refrigerant cylinders are still in use elsewhere in the world.
Unintended Consequences
More recently new EU legislation, introduced in January of this year, may only exacerbate the issue. The new EU regulation applies to the use of hydro- ? uorocarbon (HFC) R-134a. HFCs are ? uorinated greenhouse gases (f-gases) with a relatively high Global Warming
Potential (GWP). So while R134-a is an ozone-friendly, chlorine-free, energy- ef? cient, low toxicity refrigerant, its use accelerates climate change. The EU regulation (EC517/2014) calls for the total supply of HFCs across the EU to be reduced to just 63% of the 2009-2012 baseline quantity by 2018, measured as the total tonnes of carbon dioxide equiv- alent (CO2e). This sustained reduction in capacity will continue until it reaches just 21% of the original baseline ? gure 22 Maritime Reporter & Engineering News • OCTOBER 2015
