From regulatory mandates to congressional actions to increasing pressures from shareholder activists, companies have more and more reasons for developing an effective way to manage carbon emissions. The question is just how to go about doing that.
Although some pioneers in sustainability have been tracking their carbon output for a while, “three years is the longest I know that anybody has been at it very seriously,” says Pat Concessi, a climate change leader at Deloitte Canada. Since most businesses need at least three years to get a firm grip on their carbon footprint, she says, most have a long way to go.
