It has been drawn up by the Technical Committee CEN/TC 264. If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

5 ÖNORM DRAFT FprEN :2016 (E) European foreword This document (FprEN :2016) has been prepared by Technical Committee CEN/TC 264 Air quality, the secretariat of which is held by DIN. This document is currently submitted to the Formal Vote. This document has been prepared under a mandate M/478 given to CEN by the European Commission and the European Free Trade Association. FprEN 19694, Stationary source emissions Determination of greenhouse gas (GHG) emissions in energy-intensive industries is a series of standards that consists of the following parts: Part 1: General aspects Part 2: Iron and steel industry Part 3: Cement industry Part 4: Aluminium industry Part 5: Lime industry Part 6: Ferroalloy industry 3

6 FprEN :2016 (E) ÖNORM DRAFT Introduction This European Standard serves the following purposes: measuring, testing and quantifying GHG emissions from the aluminium industry; assessing the level of GHG emissions performance of production processes over time, at production sites; establishing and providing reliable, accurate and quality information for reporting and verification purposes. This European Standard can be used to measure, report and compare the GHG emissions of an aluminium production facility. Data for individual facilities, sites or works may be combined to measure, report and compare GHG emissions for a company, corporation or group. Direct fuel based emissions are not included; for calculation of this part of the GHG emissions, see FprEN The European Standard deals with sector-specific aspects for the determination of greenhouse gas (GHG) emissions from aluminium production and is based on documents mentioned under tier 3 of Section of the 2006 IPCC guidelines [6]. 4

7 ÖNORM DRAFT FprEN :2016 (E) 1 Scope This European Standard specifies a harmonized method for calculating the emissions of greenhouse gases from the electrolysis section of primary aluminium smelters and aluminium anode baking plants. It also specifies key performance indicators for the purpose of benchmarking of aluminium. This also defines the boundaries. NOTE Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
