Calculation method of carbon dioxide emission intensity from iron and steel production — Part 3: Steel plant with electric arc furnace (EAF) and coal-based or gas-based direct reduction iron (DRI) facility

This document specifies calculation methods applicable to manufacturers using an electric arc furnace (EAF) to produce steel and having direct reduced iron (DRI) facilities within their premises. This document allows the user to cover those particular cases of agglomeration of iron ore on site. It can be used to evaluate the total annual carbon dioxide (CO2) emissions and the emission factor of CO2 intensity of the entire steel production process. This document is applicable to plants producing mainly carbon steel. It includes boundary definition, material and energy flow definition and emission factor of CO2. Besides direct source import to the boundary, upstream and credit concept is applied to exhibit the plant CO2 intensity. This document supports the steel producer to establish CO2 emissions attributable to a site. Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.

Méthode de calcul de l’intensité de l’émission de dioxyde de carbone de la production de la fonte et de l’acier — Partie 3: Usine sidérurgique avec four électrique à arc (EAF) et installation de réduction directe de la fonte (DRI) à base de charbon ou de gaz

Le présent document spécifie des méthodes de calcul applicables aux fabricants utilisant un four électrique à arc (EAF) pour produire de l’acier et ayant des installations de réduction directe de la fonte au sein de leurs locaux. Le présent document permet à l'utilisateur de couvrir les cas particuliers d’agglomération de minerai de fer sur site. Il peut être utilisé pour évaluer les émissions annuelles totales de dioxyde de carbone (CO2) et le facteur d’émission de l’intensité de CO2 de l'ensemble du processus de production d’acier. Le présent document s’applique à des usines produisant principalement de l’acier au carbone. Il comprend la définition du périmètre, la définition des matériaux et du flux d’énergie, et un facteur d’émission de CO2. En dehors de l’importation des sources directes à l’intérieur du périmètre, un concept d’émissions en amont et d’émissions justifiant des crédits est appliqué pour présenter l’intensité de CO2 de l’usine. Le présent document aide le producteur d’acier à déterminer les émissions de CO2 attribuables à un site. Une conversion en consommation d’énergie et en efficacité de consommation peut être obtenue en utilisant l’Annexe A.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). 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 established has the right to be represented on that committee. 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 all matters of electrotechnical standardization.

This second edition cancels and replaces the first edition (ISO 14404-3:2017), which has been technically
revised.
The main changes are as follows:
— revision of Introduction, Terms and Definitions, and default emission factors;
— addition and revision of some emissions sources;
— clarification of the difference between "Boundary" and "Site boundary";
— addition a new informative annex, Annex D on “Decarbonization strategies and its impact in CO
