Gilead Sciences

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.

Gilead is closing in on its target to transition to 100% renewable electricity by 2025. As of 2023, 64% of global electricity demand comes from renewable sources. Strategy includes: self-generation from on-site solar arrays (notably in Cork, Ireland and U.S. facilities including Foster City, La Verne and Oceanside) meeting 4% of total electricity demand; green-tariff contracts with electricity suppliers; unbundled Energy Attribute Certificates (EACs); and a first Virtual Power Purchase Agreement (vPPA) signed in 2024 via Schneider Electric's Energize Program with Thermo Fisher, GSK and Haleon in Spain (369 MW of new solar, online 2026). Gilead is a signatory to Climate Group's RE100.

• Fleet electrification (EV100)

  Gilead committed to EV100 to transition 100% of fleet vehicles to electric or low-emissions vehicles by 2030 and increase charging infrastructure. As of 2024, 13% of global fleet is electric/low-emissions. 58 EVs in U.S. fleet via pilot program, 626 charging points in 40 locations, EV incentives in 10 countries.

• Green chemistry and solvent substitution

  Green Chemistry Working Group within Process Chemistry expanded use of greener solvents in manufacturing. Alberta facility switched from dichloromethane to 1,3-dioxolane in equipment cleaning, avoiding large volumes of less sustainable solvent. Goal to reduce hazardous waste stream toxicity.

• Energy efficiency in facilities and labs

  In 2024, Gilead surpassed its annualized energy reduction KPI of 15.5M kWh, achieving 16.6M kWh in savings ($1.8M cost savings). Reductions came from retro-commissioning (6.8M kWh), BMS optimization (4.8M kWh), facility optimization (3.4M kWh), HVAC optimization (1.3M kWh) and decommissioning. La Verne site lowered Water for Injection (WFI) system temperatures, saving 355,785 kWh/year. My Green Lab program has certified labs across six locations with 770+ participating scientists.

• Green buildings and net-zero new construction

  Gilead has earned 31 building certifications since 2016, including in 2024: six new certifications (LEED Silver/Gold for Foster City labs, NJ, DC, Sao Paolo Commercial Interiors; WELL Gold for Foster City Wellbeing Center). New Foster City research facility targeting ILFI Zero Carbon certification, 50% water savings vs baseline, 85% construction waste diversion, 10-60% recycled content for highest-impact materials.

• Supplier engagement on SBTi targets (Scope 3)

  Scope 3 comprises 93% of Gilead's total GHG emissions. Gilead engages key suppliers using segmentation and emissions contributions. Based on analysis of suppliers comprising 75% of Scope 3 emissions, ~38% of spend is associated with suppliers with SBTi-approved targets and another 16% have committed to setting targets. Starting in 2025, Gilead added a new KPI to grow SBTi-committed supplier spend by 10% annually.

• Sustainable aviation fuel & logistics

  Gilead sourced sustainable aviation fuels, avoiding 546 MT of GHG emissions in 2024. Also reduced expanded polystyrene (EPS) in cell therapy cold-chain shipping packaging by 24% by weight through redesigned insulation.
