A company's true commitment to sustainability requires not only reducing the negative impacts from its operations, but more importantly, changing its products and services to be more sustainable and help address environmental and social challenges.Dow Chemical Co. has had a long commitment to sustainability -- which I've been fortunate to see in action through Dow's engagement with my organization, the Boston College Center for Corporate Citizenship. But when I heard Rose Perkins' recent presentation during my Green Innovation class at the Carroll School of Management, it became clear just how much Dow has changed its strategies and product portfolio in the last few years.
