BS EN 19694-2:2016EN 19694-2:2016 (E) 5 Introduction The steel industry recognizes the urgent need to take action to combat climate change. Slowing and halting global warming will require substantial
25、reductions in greenhouse gas emission on a global scale. To play a part in achieving these reductions, steel production sites, recognized as major emitters of GHG, should as a first step assess their CO2emission performance relating to the production of steel products in order to identify and quanti
26、fy emission reduction opportunities. Steel production involves complex chemical reactions, successive heating cycles, and the recycling of various by-products. A variety of inputs, including raw materials, reactive agents, fuel and heat sources are transformed into a wide range of steel products, by
27、-products, waste materials and waste energy. Steel sites manufacture a wide range of products including, among others, sheet products, plate products, long products, pipe and tubes. In addition, some steel sites produce unique high-performance specialty steel products, which are created by employing
28、 various sub-processes including micro-alloying and surface treatment, thus requiring additional heat treatments. Therefore, there are no two steel sites in the world which are the same. As a consequence, a sound assessment of performance should be made independent of the production structure. Regul
29、ations related to climate change require steel companies to devise methods to reduce CO2emissions from steel sites while continuing to produce steel products from these diverse and complex steelmaking processes. To accomplish this, it is desirable to have universally common indicators for determinin
30、g the CO2emission performance of a site. It has been the usual practice to determine CO2emissions at facility level, from which a CO2intensity per unit of reference product, usually “crude steel”, can be derived. ISO TC 17/SC /WG 21 has proposed and issued a standard for the determination of CO2inte
31、nsity derived from the method developed by worldsteel (the world steel association) as ISO 14404-1 and ISO 14404-2. Although giving a valuable insight on CO2emission performance, the “CO2intensity” approach suggested by the ISO 14404 standards series has some limitations as it provides only one sing
32、le CO2value for any specific facility, regardless of the complexity of its structure. With a view to better evaluating the CO2performance of a facility along the steel value chain, the European Steel Industry has, since 2005, worked to set up CO2accounting rules aimed at carrying out the CO2emission
33、 performance assessment of steel production facilities while taking into account and properly addressing potential distortions due to differing facility structure. To this end, this standard goes beyond the mere “CO2intensity” approach to determine the performance of each process and unit that is pa
34、rt of the facility in order to identify the strengths and weaknesses in the value chain and, at a later stage, consolidate the performance at facility level. As stressed in Part 1 of this standard series, this standard does not prejudice the content or application of any other standard or legal prov
35、ision. BS EN 19694-2:2016EN 19694-2:2016 (E) 6 1 Scope 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
36、 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, defini
37、tions 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) em
38、issions; 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 appro
39、ach for the determination of CO2emissions and the assessment of CO2performance of steel facilities, providing a set of methodologies allowing for a fair and reliable assessment of the CO2performance of each individual process along the steel production value chain. It can be seen as a toolbox which
40、enables the determination of CO2emissions and the assessment of CO2performance of steel production facilities at various levels of disaggregation, establishing a sound system for: the evaluation of the global CO2performance of a steel production facility taking its production structure into account;
41、 setting a reliable basis for evaluation of the CO2reduction 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 CO2emissions of a steel facility, this standard has a strong focus on
42、 performance assessment which it strives to address through the following aspects: assessment of CO2impact, including process emissions: this methodology evaluates the total CO2emission of a steel facility, with the carbon content of the waste gases burdened as CO2to the processes giving rise to the
43、m; assessment of the actual CO2impact: this methodology evaluates the total CO2emissions released by a steel facility, but considers waste gases exported or used in a power plant as equal to natural gas in terms of CO2emissions; carbon input CO2performance at facility level: this methodology deliver
44、s an indicator comparing the facility performance with best practice, on the basis of the carbon input to the system; BS EN 19694-2:2016EN 19694-2:2016 (E) 7 CO2performance assessment at process level: this methodology delivers a set of indicators comparing process performance with best practice at
45、unit level. These indicators are then combined as a consolidated figure for the whole facility. This methodology also provides a theoretical assessment of the CO2saving potential up to best practice. 2 Normative references The following documents, in whole or in part, are normatively referenced in t
