For the fourth straight year, Newsweek has released its in-depth look at sustainability within the most wealthy companies in the world.
At its most basic, Newsweek's Green Rankings look at the 500 largest global and U.S. companies and rank them on three broad categories: environmental impact, environmental management, and environmental disclosure.
Bell Canada Enterprises (Canada/Telecommunications)
Nokia (Finland/Technology Equipment)
Fujitsu (Japan/Technology Equipment)
NKSJ Holdings (Japan/Financials)
Telefonica Brasil (Brazil/Telecommunications)
If you're not keeping track, Brazil and India each lead the way with three companies in the top 20. If we break it down by sector, financial companies were at the top with seven, followed by IT companies and telecommunications companies with five each.
One positive note, nearly all of the companies on both top 20 lists saw their green score increase from last year.
To produce these lists, Newsweek teamed with environmental research providers, Trucost and Sustainalytics. Over 700 metrics were used to determine the overall score—including emissions of nine key greenhouse gases, water use, solid-waste disposal, and emissions that contribute to acid rain and smog. The scores are weighted with metrics falling in the environmental impact and management categories receiving 45 percent (each) of the final score and environmental disclosure receiving 10 percent.
