worldsteel is one of the few associations that report at the global level and have done so since 2004 when the first industry sustainability report was published.

The steel industry recognised the need of a systematic method to measure and report on its sustainable development performance. To this end, worldsteel established a set of sustainability indicators, which were officially established in 2003.

worldsteel members report on 8 sustainability indicators every year. The indicators are aligned to the commitments underlined in the sustainable development policy. Reporting is voluntary. Values in the table below may vary slightly from previous editions of this table due to updates received from individual companies.

The indicator average results as well as the performance trends of the steel industry over a decade are provided in the environmental, social and economic sustainability pages of this section.

Environmental sustainability indicators


Indicators 1 & 2 (Greenhouse gas emissions and Energy intensity):

  • These two indicators were updated in April 2018.
  • These indicators are calculated using route-specific energy and CO2 intensity for the basic oxygen furnace and electric arc furnace. The indicators are also weighted based on the production share of each route. Indicator 1 includes CO2 emissions only as these make up approximately 93% of all steel industry greenhouse gas emissions. The 2015 figure for Indicator 2 (energy intensity) is lower due to increased use of scrap in the EAF route and increased use of by-product gas in the BOF route.

Data for 2016 is provisional for both indicator 1 & 2.

Social sustainability indicators


Indicator 5: Lost time injury frequency rate includes fatalities and is calculated based on figures including contractors and employees.

Economic sustainability indicators


Indicator 7: Investment in new processes and products includes capital expenditure and R&D investment.


Indicator 8: Data collection for Economic Value Distributed started in 2007.
