New developments are driving the need for GHG accounting programs around the world to evolve more efficiently, more effectively, and at a greater scale. On the business side, there is a trend toward managing GHG emissions along the value chain. Companies are looking up and down the supply chain and throughout the product life-cycle for GHG management opportunities. As climate policy becomes a reality in industrialized and developing countries around the world, many emerging economies are adopting voluntary national GHG mitigation targets and identifying the policies and measures to best achieve them. These trends point to the need for greatly enhanced GHG accounting capacity and tools at a global scale to ensure that mitigation actions can be measurable, reportable and verifiable.
