When we think of companies that stand out as role models of exceptionally responsible behavior in the realm of sustainability, Halliburton is hardly one of the first to spring to mind. Which is why I was a little surprised to learn that “the company we love to hate” was just named to the Dow Jones Sustainability Index (DJSI) as both a North American and a World leader. This means that they were considered to be in the top 10% among companies in the oil field services sector.
