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
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 contractors.
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.
Over 91 member and non-member companies and organisations provided data in 2010, an increase from over 80 that provided data in 2009. 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 approximately 605 mmt representing 43% of global crude steel production tonnage in 2010.
Revenue generated by the companies reporting financial data (representing approximately 35% of global crude steel production tonnage) was US$494.4 billion in 2007, US$578.0 billion in 2008, US$510.0 in 2009 and US$552.9 billion in 2010.
