Top 10 IT Sustainability Service Providers for 2024

December 29, 2023 by Joe Panettieri

Which IT service providers have built top-notch sustainability services? We took a close look at The Forrester Wave: IT Sustainability Service Providers report for Q3 of 2023. Then we compared that report to our own ongoing coverage of the green IT services market.

In Forrester's report, the research firm describes IT sustainability services as: "Services related to environmental sustainability and carbon footprint reduction exclusively in the enterprise IT stack, covering IT in the workplace, IT development, and IT infrastructure."

That generally aligns with our thoughts, especially as CIOs tap IT service providers for help with their sustainability strategies. Among the reasons:

  • By 2025, 50% of CIOs will have specific performance metrics tied to energy consumption, according to Gartner.
  • And by 2027, 75% of organizations will have implemented a data center infrastructure sustainability program, up from less than 5% in 2022, Gartner predicted.
  • Moreover, the green technology and sustainability market is expected to reach $51.09 billion by 2029, up from $13.76 billion in 2022, according to Fortune Business Insights. That’s a compound annual growth rate (CAGR) of 20.6%.
