# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for iron and steel production (notified under document C(2012) 903) (Text with EEA relevance) (2012/135/EU), Division 16

Extent: E+W+S+N.I.

BAT is to determine the order of magnitude of diffuse emissions from relevant sources by the methods mentioned below. Whenever possible, direct measurement methods are preferred over indirect methods or evaluations based on calculations with emission factors.
Direct measurement methods where the emissions are measured at the source itself. In this case, concentrations and mass streams can be measured or determined.
Indirect measurement methods where the emission determination takes place at a certain distance from the source; a direct measurement of concentrations and mass stream is not possible.
Calculation with emission factors.
