Sims Metal Management, the international metals recycling giant, has been named one of the world's 100 most sustainable companies for the fifth year in a row.
The Australia-domiciled company took the No. 15 spot in a worldwide ranking by Corporate Knights, a Toronto, Ontario-based sustainable business publication.
The annual ranking, which was launched in 2005, is prepared using several indicators, including resource management, business practices and financial health.
Topping this year's list was Umicore, a Belgium-based materials technology and recycling company that derives the majority of its revenue from clean technologies, according to Corporate Knights.
The U.S. and Canada led in country representation, with 10 companies each included in the ranking. Biogen Idec Inc., a company in the health care industry, was the highest ranked American company.
To make the list, a company must demonstrate leadership in environmental stewardship as well as business policies, according to Corporate Knights. Sims Metal Management regularly measures and reports its waste generation, carbon dioxide emissions, water consumption and energy use, according to its website.
In its 2012 fiscal year, the company reduced its waste generated by 21% and its carbon emissions by 17%. The company also has a 50% stake in LMS Generation, a landfill gas and renewable energy company that provided more than 330,000 megawatt-hours of energy during fiscal year 2012, according to its website.
Sims Metal Management did not return requests for comment.
"The Global 100 are leading a resource productivity revolution, transforming waste into treasure and doing more with less. They are steering our civilization away from ecological overshoot and back to a place of balance with our planet," Toby Heaps, Corporate Knights CEO, said in a statement.
Sims Metal Management operates more than 270 facilities worldwide, including more than 120 in the U.S., Canada and Mexico. Its business units Sims Recycling Solutions and Sims Municipal Recycling handle electronics and household recyclables, respectively.
