OPEN LETTER: Protect the integrity of the EU ETS; Abstain from using offset credits from HFC-23 and adipic acid projects

Carbon Market Watch and other organizations call on Ryanair to avoid using industrial gas offset credits, arguing that HFC-23 and adipic acid projects lack environmental integrity and undermine climate objectives.

• A decision endorsed by EU Member States in January 2011 will ban offset credits from HFC-23 and N2O from adipic acid abatement projects from the EU ETS starting 1 May 2013.
• Industrial gas credits are criticized for undermining the Montreal Protocol and EU international climate goals, lacking sustainable development benefits, and being concentrated in emerging economies rather than least developed nations.
• Data analysis indicates that many offsets from HFC-23 and N2O adipic acid projects do not represent actual emissions reductions, which directly undermines the EU's emissions reduction target.
• The authors argue that airline operators do not require the concession of a postponed ban because the aviation sector only joined the EU ETS in 2012 and the environmental issues of industrial gas projects have been known for years.
