To understand the environmental performance of a product, its entire life cycle needs to be taken into consideration. A life cycle assessment (LCA) of a steel product looks at resources, energy and emissions, from the steel production stage to its end-of-life stage, including recycling.
The life cycle of steel
Life cycle thinking: key to every aspect of sustainability
About our Life Cycle Inventory Data
The study has been carried out in accordance with the worldsteel LCI methodology report and ISO standards 14040 and 14044 and is the most comprehensive and accurate LCI dataset for steel products produced in the world.The study report for the 2020 data release provides a more detailed insight into the data collected and the results published. A key goal of worldsteel is to provide support on the environmental credentials of steel to customers and users of steel, with the intention that those that specify and use materials in applications have access to relevant data to facilitate their own informed decision-making. This is achieved by generating this LCI database for steel products and making it available to stakeholders all around the world.
