BAT reference documents (BREFs) represent the outcome of the ‘Sevilla process’. The majority of BREFs cover specific agro-industrial activities; such BREFs are referred to as 'sectoral BREFs'. However, there are also a number of 'horizontal BREFs' dealing with cross-cutting issues such as energy efficiency, industrial cooling systems or emissions from storage with relevance for industrial manufacturing in general. A specific BREF was developed for the monitoring of emissions to air and water from installations under the Industrial Emissions Directive, which is referred to as the 'ROM'. The table below presents in alphabetical order a list of all BREFs drawn up to date.
