Michael Rea and Scott Kaufman of the Carbon Trust discuss their efforts to bring about the transition to a low-carbon economy through the application of energy efficiency at mass scale and through the development of new and emerging green technologies. Taking the perspective that carbon saving equals cost saving, Carbon Trust helps companies evaluate their supply chains and industrial processes to determine where efficiency and profitability best intersect. One innovation in emissions reduction has been their development of carbon labeling standards that take a holistic view of product life-cycle: from origin to disposal.
