“Corporations have a unique role to play in creating a cleaner environment, and they also have economic incentives to use energy more efficiently as demand and costs rise globally. If every company in the S&P 500 voluntarily reported and disclosed its energy costs, clearly and explicitly as a line item on the balance sheet, there would be pressure to reduce that cost, just as there is for every other expense item. This would result in analyst and investor pressure on corporate executives to be more efficient with their energy output and to source cheaper and alternative sources, which would have a far greater impact on carbon emissions and pollution than any political treaty in history. As an added advantage, reducing costs increases profitability, which provides the appropriate incentives for corporate executives to act in their shareholders’ best interests and effect positive social change. According to PwC, 98 percent of the S&P 500 companies surveyed can link investments in emissions reduction to value creation.55 As a result, these corporations are discovering new ways to enhance efficiencies, create new markets, and build a competitive advantage.”
