OUR INDICATORS

Steel companies from around the world have been providing data for the wordsteel sustainability indicators since 2004.

These indicators provide a systematic way of measuring key aspects of our economic, environmental and social performance on a yearly basis.

In 2020, 104 steel companies and associations contributed to the data collection. Crude steel produced
by companies who reported on one or more indicators for fiscal year 2019 was 1,103 Mt, representing 59% of global crude steel production.

Access to the worldsteel data collection platform is open exclusively to worldsteel member companies.

Indicators 2010 - 2019 (10-year trends)

 

Environmental sustainability indicators

Notes:

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

Indicators 1 and 2 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.

Social sustainability indicators

Notes:

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

Economic sustainability indicators

Notes:

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

Notes:

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