Steel companies from around the world have been reporting to worldsteel on 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. The indicators are aligned to the commitments outlined in our sustainable development policy and to the UN Sustainable Development goals.
Steel companies report voluntarily on up to 8 sustainability indicators every year. In 2018, 97 steel organisations contributed data for fiscal year 2017. Crude steel produced by companies who reported on one or more indicators was 960.8 MT, representing 56.9% of global crude steel production.
The average indicator results, participation by indicator, as well as performance trends of the steel industry over a decade, are provided below.
Indicators 1 & 2 (Greenhouse gas emissions and Energy intensity):
(p) = preliminary; data collection in progress. Data is provisional for indicators 1 & 2.
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.
Indicator 5: Lost time injury frequency rate includes fatalities and is calculated based on figures including contractors and employees.
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.
