Unisys purchases low-carbon electricity through retail supply contracts with utility providers in India (solar/wind/nuclear/hydro mix, 371 MWh), New Zealand (large hydropower, 118 MWh), United Kingdom (solar/wind/nuclear/hydro mix, 3,524 MWh), and United States (solar/wind/nuclear/hydro mix, 1,251 MWh). These arrangements allow electricity to be accounted for at a zero or near-zero emission factor in the market-based Scope 2 figure. The company also intends to explore Renewable Energy Credits (RECs) for harder-to-abate Scope 2 emissions as it pursues its 75% reduction SBTi target by 2030. Total renewable electricity sourced was 5,264 MWh representing approximately 55% of total purchased electricity.

Unisys defines its Net Zero Goal as the state achieved when Scope 1 and 2 GHG emissions to the atmosphere are balanced by anthropogenic removals. At the end of the 2030 target, the company intends to neutralise any residual emissions with permanent carbon removals. It plans to purchase and cancel carbon credits for beyond-value-chain mitigation and will encourage suppliers to buy carbon credits to offset their absolute emissions. No carbon credits were retired in 2024; actual removal purchases are planned as a post-target-achievement step.

Unisys is downsizing owned and on-premise data centres and migrating to energy-efficient co-located data centres powered by renewable energy sources. In 2024 this delivered a 14.87% reduction in Scope 1+2 emissions from change in physical operating conditions. A single migration initiative generated estimated annual CO2e savings of 535 tCO2e with annual monetary savings of USD 2.75 million. The transition also reduces the company's real estate footprint in line with its hybrid working model and supports the SBTi near-term target.

sustainability_report p.113

Unisys implemented a renewable energy initiative in 2024 delivering estimated annual CO2e savings of 3,662 tCO2e through use of renewable energy contracts, generating USD 720,000 in annual monetary savings at a sub-one-year payback period. Market-based Scope 2 emissions are reduced by purchasing low-carbon electricity across India, New Zealand, the UK, and the US. The company also intends to assess RECs for harder-to-abate Scope 2 emissions globally.

sustainability_report p.288

Unisys is actively rightsizing its real estate portfolio to align with a hybrid working model, eliminating and consolidating buildings and migrating to co-working spaces. In 2024 this contributed to a 10.96% reduction in Scope 1+2 emissions per FTE and a 2.57% reduction per square foot. The energy intensity per square foot is 34.4 kWh/sq ft, and the company tracks square footage (1,448,494 sq ft in 2024) as a key denominator for emissions intensity management.
