The aim of this project is to collect and report CO2 emissions data on a site-by-site basis to give an overall emission intensity for the production of steel at that site, irrespective of the final products that are being made.
The methodology that is used has now been published as an International standard, ISO 14404:2013 - Calculation method of carbon dioxide emission intensity from iron and steel production. This consists of two parts: Part 1: Steel plant with blast furnace and Part 2: Steel plant with electric arc furnace (EAF). This is an intensity-based approach for the measurement of CO2 emissions. This now globally consistent methodology will allow production to be normalised CO2 emission comparisons between sites (regions or countries are not relevant only business practices have an impact).
Involvement in the CO2 data collection initiative is not exclusive to worldsteel members only, and non-members can use the system. Data is collected in an online tool and is hosted externally on dedicated servers with ISO 27001 accreditation.
worldsteel keeps the data secure and confidential and is only reported to those that contribute and reports will not be published apart from global averages for the entire industry or processes. The aim of the project is to obtain a base level of emissions for the industry for the two key process streams. The data collection methodology and standard is designed to ensure that sites report emissions use the same boundaries and parameters. Once data is reported back to the member companies they can develop their own plan to make reductions in emissions and obtain a level closer to the best in class. worldsteel can develop a global impact for the industry on the total emissions both for CO2 and GHG. The IEA report for CO2 emissions from fossil fuels is used to determine the global uprising of CO2 and GHG.
