Global Corporate Social To reduce ADP’s overall greenhouse gas emissions, we continue to assess and improve the energy efficiency of our data centers. We look for ways to conserve energy by implementing passive design features, reconfiguring office design and investing in efficient hardware and cooling systems.
We continue to rationalize our data center network as we offload some ADP-hosted workloads. ADP has decommissioned 24 data center facilities since 2015 and plans to rationalize another 4 through 2022, contributing to a reduction in carbon footprint.
ADP's average data center Power Usage Effectiveness (PUE) increased slightly from 1.5475 to 1.610 between 2018 and 2019. However, energy usage [Scope 2 (Location-Based)] emissions from these facilities decreased from 36,856.40 in 2018, to 30,762.64 in 2019, reflecting a 16% decrease!
