KIEV, March 7 – The Energy Community demands that Ukraine reduce sulfur content of its oil products while bringing quality standards in line with European Union requirements, says Energy Community Secretariat Director Janez Kopac.

"Last week we, for instance, opened a case against Ukraine for its failure to transpose the directive on the sulfur content of liquid fuels. Maybe the opening of a case is a way to start a structured dialogue with the Ukrainian authorities," he said in an interview with Interfax-Ukraine.
