DS/EN 19694-2:2016

This European Standard provides a harmonized methodology for calculating GHG emissions and GHG performance in the steel industry. This European Standard applies to facilities producing any of the multiple products of the steel value chain. It is supported by a set of worksheets [1]. This European Standard deals with the specific aspects for the determination of GHG emissions from steel production and the assessment of emission performance. This standard is to be used in conjunction with EN 19694-1, which contains overall requirements, definitions and rules applicable to the determination of GHG emissions for energy-intensive sectors, thereby providing a common methodological approach. EN 19694-1 and EN 19694-2 provide a harmonized method for: a) measuring, testing and quantifying methods for the determination of greenhouse gas (GHG) emissions; b) assessing the level of GHG emissions performance of production processes over time, at production sites; c) the establishment and provision of reliable and accurate information of proper quality for reporting and verification purposes. In addition, this standard provides a stepwise approach for the determination of CO2 emissions and the assessment of CO2 performance of steel facilities, providing a set of methodologies allowing for a fair and reliable assessment of the CO2 performance of each individual process along the steel production value chain. It can be seen as a toolbox which enables the determination of CO2 emissions and the assessment of CO2 performance of steel production facilities at various levels of disaggregation, establishing a sound system for: - the evaluation of the global CO2 performance of a steel production facility taking its production structure into account; - setting a reliable basis for evaluation of the CO2 reduction potential in a facility and the contributing processes; - setting a basis for accurate evaluation of new technologies. Next to the determination of the direct and indirect CO2 emissions of a steel facility, this standard has a strong focus on performance assessment which it strives to address through the following aspects: - assessment of CO2 impact, including process emissions: this methodology evaluates the total CO2 emission of a steel facility, with the carbon content of the waste gases burdened as CO2 to the processes giving rise to them; - assessment of the actual CO2 impact: this methodology evaluates the total CO2 emissions released by a steel facility, but considers waste gases exported or used in a power plant as equal to natural gas in terms of CO2 emissions; - carbon input CO2 performance at facility level: this methodology delivers an indicator comparing the facility performance with best practice, on the basis of the carbon input to the system; - CO2 performance assessment at process level: this methodology delivers a set of indicators comparing process performance with best practice at unit level. These indicators are then combined as a consolidated figure for the whole facility. This methodology also provides a theoretical assessment of the CO2 saving potential up to best practice.
