CDP is considered a gold standard of environmental reporting, and Cisco has reported to CDP since 2005. CDP runs the global disclosure system for investors, companies, cities, states, and regions to manage their environmental impacts. The CDP Climate A List includes companies from around the world that have been identified as leaders in their reporting and actions to reduce greenhouse gas emissions. Cisco's 2025 CDP Climate and Water Response is available here.
