Mexico's secretariat of environmental and natural resources, Semanart, has endorsed the environmental license of Mexico’s largest integrated steelmaker Altos Hornos de Mexico (AHMSA), the steelmaker said.
AHMSA’s environmental license, also known as the “unique” or the integrated environment license (LAU), was last updated in 2010. Until 2009, Mexico had different a regulation overseeing AHMSA’s operations.
Mexico requires companies that release emissions to operate under a LAU. The license attests the company meets certain environmental criteria as a clean industry.
