We already use teleconferencing to limit air travel, and we are currently in the process of examining additional initiatives, such as: • Increasing access to low-emission rental cars for employee travel • Partnering with airlines that focus on reducing their emissions • Tracking the actual carbon emissions associated with employee flights, rather than using more generic emissions factors to calculate our travel footprint We have begun to request that hotels we do business with explain how they can meet the disclosure requirements of the emerging Hotel Carbon Measurement Initiative (HCMI) standard.
