The worldsteel Climate Action data collection programme recognises steel producers that have fulfilled their commitment to participate in the worldsteel CO2 emissions data collection programme.  

The accredited organisations are recognised as Climate Action data providers (formerly named ‘Climate Action members’).

Participation is open exclusively to worldsteel member companies (steel-producing sites or companies). For further details, please contact Rizwan Janjua, Head, Technology (


In 2008, Climate Action data collection programme was launched, under which companies report data on site- or company-level CO2 emissions. A participating company or site receives a report showing the process route average emission data and range to which it can compare itself.

The data collection programme is at the core of the steel industry’s global steel sectoral approach to climate change. Based on a common methodology, definitions and agreed boundaries, the data collection programme enables individual steel plants to compare themselves against both average and best performance and identify its scope for improvement.


Recognition can be obtained at a corporate level or at a site level as long as data has been received for more than 90% of total crude steel production.

The data must be complete, verifiable and approved for each year of collection. The collection process is overseen by worldsteel staff and verified by a panel of experts who review all submissions against standardised parameters and guidelines.

The data is held in the strictest confidence and will be known only to the company or site itself and worldsteel project staff. A participating company or site will receive a report showing the process route average emission data and range to which it can compare itself.

The recognition scheme is governed by the worldsteel Board of Members.

The aim of the climate action 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.

A secure database for data collection

The methodology that is used has 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 globally consistent methodology allows normalised CO2 emission comparisons to be made between sites. (regions or countries are not relevant only business practices have an impact).

Involvement in the CO2 data collection initiative is exclusive to worldsteel members. Data is collected in an online tool and is hosted externally on dedicated servers with ISO 27001 accreditation.

A user guide clearly outlining the data collection process is available for download from the right of this page.

How is the data used

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.

Climate Action data providers 2021

Data provider branding and certification

Any company or site that takes part in the data collection programme can apply for a certificate from worldsteel ( A certificate of recognition will be issued following the approval of data. The member companies are recognised as Climate Action data providers (formerly named ‘Climate Action members’).

The certificate also allows the recipient to use the Climate Action data provider logo on any of their materials, for example, on publications, websites or marketing materials. For more details contact

The recognition period is for one year from the time of issue of the certificate. If the company or site no longer submits approved data to the programme, they must cease using the logo in any shape or form.

Data submission opens in February and runs until the last working day of May.

The list of companies granted a Climate Action Certificate for the last completed data submission cycle is published on in September.
