The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been estab

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

Slowing and halting global warming requires reductions in GHG emissions on a global scale. To play a part in
18、achieving these reductions, it is necessary for steel plants to identify the amount of CO2emitted during the production of steel products, in order to identify next opportunities for reduction of CO2.The production process of steel involves complex chemical reactions, various heating cycles, and the
19、 recycling of various by-products. This variety of imports, including raw materials, reactive agents, fuel and heat sources are transformed into wide range of steel products, by-products, waste materials and waste heat.Steel plants manufacture various products including: sheet products, plate produc
20、ts, long products, pipe and tubes and many other types of products. In addition, steel plants produce unique speciality grade steel products with high-performance, which are achieved by various sub-processes including micro-alloying and applying surface treatments like galvanizing and coating that r
21、equire additional heat treatments. Therefore, none of the steel plants in the world is exactly identical.Climate regulations in each country require steel companies to devise methods to lower CO2emissions from steel plants while continuing to produce steel products by these diverse and complex steel
22、making processes. To accomplish this, it is desirable to have universally common indicators for determining steel plant CO2emissions.There are many methods for calculating CO2emission intensity for steel plants and specific processes. Each method was created to match the objectives of a particular c
23、ountry or region. In some cases, a single country can have several calculation methods in order to fulfill different objectives. Every one of these methods reflects the unique local characteristics of a particular country or region. As a result, these methods cannot be used for comparisons of CO2emi
24、ssion intensity of steel plants in different countries and regions.The World Steel Association (worldsteel), which consists of more than 130 major steel companies in 55 countries and regions of the world, has been working on the development of a calculation method for CO2emission intensity of steel
25、plants to facilitate steel plant CO2emissions improvement by the objective comparison of the intensity among the member companies steel plants located in various places in the world. An agreement was reached among members, and worldsteel has issued the method as a guideline called “CO2Emissions Data
26、 Collection User Guide.” Actual data collection among worldsteel members based upon the guide started in 2007. Furthermore, worldsteel is encouraging even non-member steel companies to begin using the guide to calculate CO2emission intensity of their steel plants.This calculation method establishes
27、clear boundaries for collection of CO2emissions data. The net CO2emissions and production from a steel plant are calculated using all parameters within the boundaries. The CO2emission intensity of the steel plant is calculated by the net CO2emission from the plant using the boundaries divided by the
28、 amount of crude steel production of the plant. With this methodology, the CO2emission intensity of steel plants is calculated irrespective of the variance in the type of process used, products manufactured and geographic characteristics.This calculation method only uses basic imports and exports th
29、at are commonly measured and recorded by the plants; thus, the method requires neither the measurement of the specific efficiency of individual equipments or processes nor dedicated measurements of the complex flow and recycling of materials and waste heat. In this way, the calculation method ensure
30、s its simplicity and universal applicability without requiring steel plants to install additional dedicated measuring devices or to collect additional dedicated data other than commonly used data in the management of plants. However, because different regions have different energy sources and raw ma
31、terials available to them, the resulting calculations cannot be used to determine a benchmark or best in class across regions.With this method, a steel company can calculate a single figure for the CO2emissions intensity of a plant as a whole. As was explained earlier, most steel plants manufacture
32、vast range of products with various shapes and specifications. This calculation method ensures the simplicity and universal applicability by not accommodating the differences in the production processes of such diverse products, and treats ISO 2013 All rights reserved vBS ISO 14404-1:2013ISO 14404-1
33、:2013(E)a whole steel plant as one unit with one CO2emission intensity. Therefore, this calculation method is not applicable for calculating and determining the carbon footprint of any specific steel product. Also, and for this reason, this method can be used neither for establishing caps or benchma
34、rks for emissions under emissions trading scheme in any specific local or regional economic system, nor for the generation of CO2data that would allow a comparison of CO2intensities of production processes that are operated inside the site.vi ISO 2013 All rights reservedBS ISO 14404-1:2013INTERNATIO
35、NAL STANDARD ISO 14404-1:2013(E)Calculation method of carbon dioxide emission intensity from iron and steel production Part 1: Steel plant with blast furnace1 ScopeThis part of ISO 14404 specifies calculation methods for the carbon dioxide (CO2) intensity of plant where steel is produced through a b
