1 Global Perspectives and Best Practice in the Steel Industry

2 World Crude Steel Production (1950 to 2011) mln t Crude steel production by region EU 27 Other Europe CIS North America South America Africa and Middle East Asia and Oceania 02 August

3 Steel Industry Improvements 02 August

4 worldsteel CO 2 Data Collection Energy Use in the Steel Industry Breakthrough technologies 02 August

5 02 August worldsteel CO 2 Data Collection

6 CO 2 data Collection Methodology CO 2 emissions = Direct + Indirect Credit CO 2 intensity = CO 2 emissions (tonne) / crude steel (tonne) 02 August

7 2011 CO 2 Data Collection in progress Number of companies Number of sites Region Global EU Other Europe C.I.S North America South America Africa Middle East Developed Asia Other Asia (excl. China & India) China India August 2012

8 Trend of Averages 4 Survey Years of CO 2 data CO 2 emissions intensity of each route [tco 2 /tcs] BF-BOF EAF August 2012

9 4 year trend of CO 2 intensity for BF-BOF route CO 2 Intensity [tco 2 /tcs] weighted by production volume Every year the data collection includes different participations Averaged only for those who submitted data 4 years in a row. CO 2 methodology model reflects the economic trend Production drop under BF capacity decrease its efficiency Collection of all submitted sites (over 80 sites) Maximum ~1.5% variation Collection of 4 years fully submitted sites (57 sites) World steel production volume by BOF [Bt]

10 4 year trend of CO 2 intensity for EAF route CO 2 Intensity [tco 2 /tcs] weighted by production volume Every year the data collection includes different participations Averaged only for those who submitted data 4 years in a row. The data collection model reflects the economic trend Economic recession likely reduce external scrap level CI 0.80 Collection of all submitted sites (67~80 sites) 0.71 Maximum ~7% fluctuation Collection of 4 years fully submitted sites (35 sites) World steel production volume by EAF [Bt]

11 Energy Use in the Steel Industry 11

12 Objectives of the Energy Project: Provide opportunities to decrease the energy intensity / ton of crude steel. Provide best or good practices to utilize energy sources more effectively. Provide best or good practices to recover energy (heat, gas) where practical. Enabling companies to develop plans for plant energy intensity reduction. Practice benchmarking allows prioritization of investments to improve energy efficiency with the biggest impact. 12

13 Energy project coverage members steel production in ,413.6 mmt of crude steel was total world steel production in 2010 Energy use project members produced 373,3 mmt of crude steel in mmt of steel represent approximately 26.4% of the total world steel production in 2010
