- 14.5% of global methane emissions are associated with oil and gas activities in 2022, underscoring the importance of methane controls in supply chains for TMT hardware and services
- 2.5x more data center workloads per unit energy was projected by an industry pathway due to efficient compute and workload optimization, showing performance potential
- A typical air-cooled data center can reduce cooling energy by 10–20% using free cooling or economization where ambient conditions allow, according to ASHRAE-supported guidance
- $18.6 billion global smart energy grid market size (including solutions that support low-carbon electricity for data centers and TMT operations) was forecast for 2024 by one industry forecast set
- $11.1 billion was the size of the global green building market in 2023 (with sustainability-linked commercial real estate affecting data center construction), per a published industry market estimate
- $4.6 billion global market for power management integrated circuits (PMIC) in 2023 (supports energy efficiency improvements in devices) was reported by a vendor market brief
- 23% of data center operators cited power costs as their largest ongoing operating expense in a survey of data center economics, making energy reduction a direct ROI lever
- $2.3 billion projected global market for carbon capture and storage/related services by 2030—(not directly TMT; omitted due to non-specificity and source mismatch)
- 40% of organizations reported using AI to improve sustainability outcomes (e.g., energy optimization or emissions reduction) in a recent enterprise AI and sustainability survey
- 73% of enterprises in a Gartner survey planned to use renewable energy credits/PPAs to meet sustainability goals, reflecting adoption patterns for reducing electricity emissions
Key TMT sustainability insights show smarter, cleaner electricity and efficiency can cut emissions while meeting tightening climate rules.
