Concerns About Climate Change Not Taken Lightly By Nucor

As a member of a very carbon-intense industry sector, Nucor is keenly aware of its responsibilities regarding environmental protection. Issues concerning climate change and greenhouse gas emissions are of vital concern to the company. As a result, Nucor is a strong supporter of the U.S. Government's Climate VISION program which seeks to voluntarily lower greenhouse gas emissions in the United States without sacrificing economic growth.

In addition, Nucor continues to search for other ways to improve energy efficiency and to research and invest in new technologies that can facilitate further reductions in greenhouse gas emissions from the steel making and recycling process.

For example, with Nucor's Castrip® process, energy and associated carbon required to cast and roll carbon steel sheet are reduced by approximately 60 percent from conventional production methods.

As proof, even though the Kyoto Protocol calls for a 7 percent reduction in greenhouse gas emissions between 1990 and 2012, the U.S. iron and steel industry had already achieved a 28 percent reduction by 2005 — a figure that surpassed the Kyoto target by more than 240 percent.

To assure that Nucor remains one of the safest, productive and environmentally conscious companies in the world, Nucor's board regularly reviews management's efforts to affect and respond to such issues through research, analysis, educational efforts and participation in business and governmental programs.

The growth of Nucor contributes significantly to the reduction in greenhouse gas emissions. As Nucor grows, the percent of recycled steel manufactured in the U.S. also grows, displacing other processes that emit significantly higher greenhouse gases.
