Key Takeaways
- Global data center count reached 8,000 hyperscale facilities in 2023, consuming 2% of global power
- Hyperscale data centers grew 24% YoY to 807 in 2023
- Data centers used 116-200 TWh in Europe in 2020, 3.2% of EU electricity
- E-waste generated globally reached 57.4 Mt in 2021, with only 17.4% formally recycled
- Tech sector produces 50 million tons of e-waste yearly, growing 3-5% annually
- Smartphones discarded annually number 1.7 billion units, containing $55 billion in recoverable materials
- The global ICT sector accounted for 2.1% to 3.9% of greenhouse gas emissions in 2022, equivalent to approximately 530 to 990 million tonnes of CO2
- Tech companies' data centers consumed about 240-340 TWh of electricity in 2020, representing 1-1.3% of global electricity use
- By 2030, data centers could consume up to 1,000 TWh annually, doubling their current footprint and equaling Japan's total electricity consumption
- Google committed to net-zero emissions across operations and supply chain by 2030
- Microsoft pledged carbon negative by 2030, removing all historical emissions by 2050
- Apple targets 100% renewable energy for supply chain by 2030
- Global supply chain for tech minerals emitted 240 Mt CO2 in 2020
- Cobalt mining for batteries causes 10-20g CO2e per gram extracted
- 80% of rare earth processing occurs in China, with high pollution emissions
Data centers and device supply chains keep rising fast, but efficiency gains and renewable energy targets can curb emissions.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
