*In the period 2004-2009, zinc refining has shifted from the coke intensive pyrometallurgical ISF process towards the more
energy efficient electrolytic RLE process. In 2015, there was 1 ISF plant left in the EU providing only 3% of the EU
production, down from 18% in 2004. This switch resulted in a 38% reduction of total CO2 emissions since 1990. In 2015,
indirect emission were 40% related to coal (mainly from ISF) and 60% to gas and fuel (RLE process).
