ICT is responsible for 1.7 million GWh of electricity use globally in 2020, and the gap between inefficient and best-practice data centre operations can cut that electricity demand by up to 40%. At the same time, only 28% of large organisations say they already measure the carbon footprint of their IT workloads for sustainability reporting, which helps explain why progress looks uneven. This post brings the most telling, quantified signals together to show where efforts are accelerating and where they still stall.
Key Takeaways
- 40% lower electricity consumption is achievable for data centre workloads when moving from inefficient to best-practice operations (IEA scenario results).
- 1.7x fewer emissions are achieved when workloads are consolidated onto fewer servers using virtualization (average across scenarios in a meta-analysis).
- 1.25 million GWh of electricity consumption by ICT globally was estimated for 2020, reinforcing the scale of energy efficiency opportunities.
- 28% of organisations reported that they measure the carbon footprint of their IT workloads to support sustainability reporting (survey of large organisations).
- 3.5% of total global GHG emissions was estimated to be linked to the full lifecycle of digital technologies (including hardware, networks, and data centres) in 2019.
- USD 28.8 billion was the global market size for green cloud computing in 2023, forecast to grow as enterprises pursue lower-carbon IT infrastructure.
- USD 10.2 billion global market size for data centre sustainability solutions in 2022.
- USD 4.3 billion global market size for energy management systems (including data-centre energy management applications) in 2022.
- 2,530 g of CO2e per kg of device was estimated for smartphone manufacturing embodied emissions in a 2020 lifecycle assessment (study average).
- 27% reduction in climate impact is achievable by extending smartphone lifetime by 2 years, according to a 2021 lifecycle assessment review.
- 42% of global gold demand is met through recycling in 2020, supporting the case for circularity relevant to ICT electronics.
- 50% of cloud users reported that cloud providers offer better energy efficiency than on-premise data centres (survey results from an industry research firm).
- 61% of enterprises are using or piloting carbon accounting tools for ICT infrastructure and digital services (survey by Gartner/industry).
- 73% of IT decision-makers say they have a sustainability strategy that includes emissions reduction targets for IT operations (survey by Spiceworks or equivalent).
- 1.5x more CO2e emissions are associated with data center workloads without energy-efficient practices compared with best-practice operations in a published comparative assessment (ratio reported in study).
Best-practice data centre and IT efficiency can cut emissions and energy sharply, but most firms are still catching up.
