Energy industry free from sf 6: latest market developments

Apr 11, 2019 · The European Commission urges for sf 6 alternatives . In 2014, the European Commission reinforced a 2006 F-Gas regulation No. 517/2014 with the aim of reducing the EU’s F-gas emissions by two-thirds from 2014 levels by 2030. Within the EU, sf 6 was banned for most of its applications, except for its use in the energy industry – its main consumer.
