The main piece of EU legislation regulating the environmental impact of large industrial installations is Directive 2010/75/EU of the European Parliament and of the Council of 24 November 2010 on industrial emissions. The so-called 'BAT Conclusions’ (BAT = best available technology) are among the novelties that Directive 2010/75/EU introduced into the EU law. The concept is that BAT is a moving target, since technologies and social values are continually changing.
