International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on

22、IntroductionThe steel industry recognizes there is an urgent need to take actions concerning climate change. Slowing and halting global warming requires reductions in GHG emissions on a global scale. To play a role in achieving these reductions, it is necessary for steel plants to determine the amou

23、nt of CO2emitted during the production of steel products, in order to identify further CO2reduction opportunities.The steel production process involves complex chemical reactions, several heating cycles and the cycling of various by-products. This variety of imports, including raw materials, reactiv

24、e agents, fuel and heat sources, are transformed into a wide range of steel products, by-products, waste materials and waste heat.Steel plants manufacture various products including: flat items, long items, pipes, tubes and many others. In addition, they produce unique specialty-grade steel products

25、 with high performance. These are achieved using a number of sub-processes including micro-alloying and applying surface treatments like galvanizing and coating, which require additional heat treatments. The variety of products produced and processes used means there are not two identical steel plan

26、ts in the world.Climate regulations in each country require steel companies to devise methods to lower CO2emissions while continuing to produce steel products by these diverse and complex steelmaking processes. To accomplish this, it is desirable to have universally common indicators for determining

27、 steel plant CO2emissions.There are many methods for calculating CO2emission intensity from steel plants and specific processes. Each method was created to meet the objectives of a particular country or region. In some cases, a single country can have several calculation methods in order to fulfil d

28、ifferent objectives. Each one of these methods reflects the unique local characteristics of a particular country or region. Therefore, these methods cannot be used for comparisons of CO2emission intensity from steel plants located in different countries and regions.The World Steel Association (world

29、steel), which consists of more than 161 major steel companies in 60 countries and regions of the world, has been working on the development of a calculation method for CO2emission intensity to facilitate the improvement of steel plant CO2emissions. The calculation method is based on an objective com

30、parison of CO2emissions intensity among the member steel companies located in different places in the world. An agreement was reached among members and worldsteel issued the method as “CO2Emissions Data Collection User Guide”. Actual data collection among worldsteel members based upon the guide star

31、ted in 2007. Furthermore, worldsteel is encouraging non-member steel companies to begin using the guide to calculate CO2emission intensity of their steel plants.The calculation method establishes clear boundaries for the collection of CO2emissions data. The net CO2emissions and production from a ste

32、el plant are calculated using all the parameters within the boundaries. The CO2emission intensity is calculated by the net CO2emission from the plant using the boundaries divided by the amount of crude steel production of that plant. With this methodology, the CO2emission intensity of steel plants i

33、s calculated irrespective of the type of process used, products manufactured and geographic characteristics.This calculation method only uses basic imports and exports that are commonly measured and recorded by the plants; thus, the method requires neither the measurement of the specific efficiency

34、of individual equipment or processes nor dedicated measurements of the complex flow and recycling of materials and waste heat. In this way, the calculation method ensures its simplicity and universal applicability without requiring steel plants to install additional dedicated measuring devices or to

35、 collect additional dedicated data other than those commonly used in the plant management. However, since different regions have different energy sources and raw materials available to them, the resulting calculations cannot be used to determine a benchmark or best in class across regions.With this

36、method, a steel company can calculate a single figure for the CO2emissions intensity of a site as a whole. Most steel plants manufacture a vast range of products with various shapes and specifications. This calculation method is simple and universally applicable because it is not affected ISO 2017 A
