Best Available Techniques Reference
Also "Best Available Techniques Reference Document“ or "BAT Reference“ or "BAT Reference Document". These documents are provided by the European Union and contain (among others) information on a specific industrial/agricultural sector, on the techniques and processes used in this sector, current emission and consumption levels, techniques to consider in the determination of the best available techniques and emerging techniques.
