Sustainability indicators
Sustainability indicators were established in 2003 and data reported for these indicators were published for the first time in 2005. Each indicator aims to address one or more of the commitments outlined in the sustainable development policy.
Indicator performance trends are discussed in the Environmental, Social and Economic Sustainability pages.

Notes
Indicators 1 and 2: These indicators are calculated using route-specific energy and CO2 intensities for three steel production routes: basic oxygen furnace, electric arc furnace and open hearth 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. For more information on GHG emissions in the steel industry see the worldsteel LCA Methodology Report.
Indicator 5: includes employees and contractors.
Indicator 8: Economic value distributed quantifies the value distributed to society and includes operating costs (payments to suppliers, contractors, etc.), employee wages and benefits, dividends paid to all shareholders, interest payments made to providers of loans, payments to government (gross taxes and royalties), and community investments (voluntary contributions and investments of funds in the broader community, including donations and scholarships, etc.). (p) = preliminary; data collection in progress
The number of companies reporting varies from year-to-year. This has an influence on the average results. The aim is always to increase global tonnage coverage and the number of companies reporting, to increase the reliability of the averages. Differences in data from “World Steel in Figures 2011” are due to additional data being received since its publication in June 2011.
100 member and non-member companies and organisations provided data for 2011 figures, an increase from 91 that provided data for 2010. Crude steel produced by the participating companies (consolidated tonnage) was approximately 493 mmt representing 40% of global crude steel production tonnage in 2009 and increased to 605 mmt representing 43% of global crude steel production tonnage in 2010 and 676 mmt representing 45% of global crude steel production tonnage in 2011.
Revenue generated by the companies reporting financial data was US$552.9 billion in 2010, which increased to US$665.9 billion in 2011 (representing approximately 35% of global crude steel production tonnage from 2007 to 2010 and 37% of global crude steel production tonnage in 2011).
