Unisys Corporation

Carbon per million dollars of revenue. The legacy industry-standard reference (CDP, MSCI). Useful for cross-sector context, but distorted by margin — high-margin firms appear artificially efficient. Read alongside the operational and asset intensities for the full picture.

OpEx (operating expenditure) is the running cost of the business — staff, services, energy, materials. This shows how carbon-intensive operations are per million dollars of spend. Removes the margin distortion that revenue-based ratios introduce.

EVIC (Enterprise Value Including Cash) is the firm's total capital footprint — equity + debt + cash + minority interest. The EU's standard intensity measure (SFDR PAI 3) — answers: how much carbon does each million of capital deployed in this business produce?

PP&E (Property, Plant & Equipment) plus leased real-estate assets is the firm's physical infrastructure on the balance sheet. This shows the carbon intensity of that physical footprint — uses Scope 1+2+3 for consistency with the other headline intensities. Surfaces stranded-asset risk for asset-heavy firms.

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.

• Data centre consolidation and migration to co-location facilities

  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.

• Renewable energy procurement for Scope 2 reduction

  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.

• Real estate footprint optimisation and hybrid work model

  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.

• Business travel reduction

  GHG emissions per headcount in 2023 reduced by approximately 14% vs. 2019 through reducing corporate air and vehicle travel. Employees selecting environmentally friendly travel options (e.g., train rather than plane) reduced 730 tonnes of carbon in 2023.

• Energy efficiency / server virtualization

  In 2023, dedicated physical servers were migrated to virtual servers running physical access control for over 50 sites worldwide, reducing energy consumption by 15,000 kWh. Continued migration of data centers in New Zealand and US to more efficient facilities.

• Right-sizing real estate footprint

  During 2023, Unisys right-sized facilities in Augusta GA, Auckland NZ, Eagan MN, Sydney AU, and Salt Lake City UT, eliminating 5,168 tonnes of CO2 by closing/consolidating offices and data centers. Reduced power consumption globally by over 47% since 2019. Migrating from on-premises to co-location data centers for energy efficiency.

• Supplier SBTi engagement: 78% of Cat 1+2 spend with SBTi-aligned suppliers by 2027

  Unisys has an SBTi-approved supplier engagement target requiring 78% of its spend in Categories 1 and 2 (purchased goods/capital goods) to be with suppliers holding SBTi-aligned targets by 2027. In 2024, 62% of spend (79% of goal) was with qualifying suppliers, up from 47% in 2023. The number of SBTi-aligned suppliers grew from 78 in 2023 to 94 in 2024. Engagement includes annual supplier questionnaires, training, sharing best practices, and collecting GHG data.

• Low-carbon IT solutions: cloud and hybrid computing services

  Unisys classifies cloud-based and hybrid computing services as low-carbon products, representing approximately 10% of total revenue. The company estimates 1,800 metric tonnes CO2e avoided per functional unit compared to legacy on-premise solutions (prior solution ~2,800 tCO2e vs. new solution ~1,000 tCO2e). The transition to co-located data centres with low-carbon technology solutions also enables clients to reduce their own Scope 2 and 3 emissions from purchased IT services.

• Supplier engagement via EcoVadis

  Unisys partners with EcoVadis to access ESG scores of select suppliers; 177 suppliers assessed for environmental and social impacts via EcoVadis. Procurement team has embraced ESG as integral to end-to-end sourcing/contracting in 2023, working with suppliers to identify joint emissions reductions and supply chain efficiencies.

• End-of-life electronics circularity program

  Since 1997 Unisys' EOL product disposition program has recovered 45.8 million pounds of obsolete products. Since 2018, refurbished 65,247 assets for reuse, recycled 78,421 assets for material recovery, and avoided 18,883 tonnes of CO2e. In 2023, over 300,000 lbs of EOL electronics collected for recycling.
