EC and EFTA have given a mandate (M/478) to CEN for the standardization of the determination of greenhouse gas emissions from energy-intensive industries. This standard "Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 1: General aspects" deals with general aspects for the determination of GHG emissions from sector-specific sources as of the steel and iron, cement, aluminium, lime and ferroalloy producing industry. The complete list of worked out standards reads as follows: prEN xxxxx, Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 1: General aspects prEN xxxxx Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 2: Steel and iron industry prEN xxxxx Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 3: Cement industry prEN xxxxx Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 4: Aluminium industry prEN xxxxx Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 5: Lime industry prEN xxxxx Stationary source emissions Determination of Greenhouse Gas (GHG) emissions in energy intensive industries Part 6: Ferroalloy industry This standard contains in particular definitions and rules valid to all above enlisted sector-specific standards, provides common methodological issues and defines the details for applying the rules for the harmonised methods which include: a) measuring, testing and quantifying methods for greenhouse gas (GHG) emissions of the above mentioned sector-specific sources in the cited standards; b) assessment of the level of GHG emissions performance of production processes over time, at production sites; c) establishment and provision of reliable, accurate and quality information for reporting and verification purposes; The application of this standard to the above mentioned sector-specific standards ensures accuracy, precision and reproducibility of the obtained results and is for this reason a normative reference standard, umbrella standard resp.
