The American Iron and Steel Institute (AISI) reported on January 14 that the United States steel industry has achieved a new milestone in energy efficiency by reducing its energy intensity per ton of steel shipped by approximately 33 percent since 1990. This represents a further improvement since AISI announced a 29 percent reduction in 2006. Because of the close relationship between energy use and greenhouse gas emissions, the industry’s aggregate carbon dioxide (CO2) emissions per ton of steel shipped have also been substantially reduced. Compared to the Kyoto Protocol’s call for an average U.S. reduction of 7 percent in greenhouse gas emissions between 1990 and 2012, this means the American steel industry has already surpassed the Kyoto target.
“This improvement in energy efficiency is evidence of the steel industry’s longstanding commitment to sustainability,” Thomas J. Gibson, AISI president and CEO, said. “This commitment has brought our processes almost to the limit of energy-efficiency. Our future plans are built round sectoral programs, such as the Asia Pacific Partnership – where steelmakers and their governments in China, India, Australia, Canada, Japan, and Korea, with us, are discussing energy intensity reduction targets until 2020. In the long-term, we are working on developing breakthrough steelmaking processes that emit little or no CO2.”
On average, 1.14 tons of carbon dioxide was emitted in 2007 for every ton of steel produced in the United States. The low CO2 intensity of American-manufactured steel coupled with its infinite recyclability is why products made of steel have such low environmental impacts during their life cycle. It is why steel is the material of choice in so many applications.
AISI serves as the voice of the North American steel industry in the public policy arena and advances the case for steel in the marketplace as the preferred material of choice. AISI also plays a lead role in the development and application of new steels and steelmaking technology. AISI is comprised of 25 member companies, including integrated and electric furnace steelmakers, and 130 associate and affiliate members who are suppliers to or customers of the steel industry. AISI's member companies represent over 70 percent of both U.S. and North American steel capacity. For more news about steel and its applications, view AISI’s Web site at www.steel.org.
