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 targeting 100% renewable electricity by 2025, with 64% achieved as of 2023. Approach combines: self-generation from solar arrays at Foster City, La Verne, Oceanside and Cork (4% of total electricity demand); green tariff contracts with local utilities; and unbundled energy attribute certificates (EACs) where green tariffs are not available. In 2024, Gilead signed its first virtual Power Purchase Agreement (vPPA) in Spain through Schneider Electric's Energize Program, in partnership with Thermo Fisher Scientific, GSK and Haleon, expected online 2026 delivering 369 MW of new solar to the European grid. Signatory to RE100.

Gilead's climate strategy emphasizes reductions and renewables rather than carbon removals. The report does not disclose use of DAC, BECCS, biochar, soil carbon or nature-based removals to meet its net-zero 2030 operations target. The strategy focuses on the four pillars of Rethinking, Reducing, Replacing and Restoring — with 'Restoring' framed as investing in solutions to offset residual emissions and improve water quality, but no specific removal volumes, vintages or certifications are stated.

• Sustainable packaging & single-use plastic elimination

  96% of secondary/tertiary packaging is designed to be recyclable (representing 98% of packaging volume). 89% of facilities have eliminated single-use plastics (excluding R&D/manufacturing). Testing 15-30% post-consumer recycled content plastics and 30-100% recycled paper at largest packaging facilities. Cork launched first product packaging with 70% recycled cartons and ~100% recycled corrugated shippers. Reduced EPS Styrofoam in cell therapy packaging by 24%.

• Energy efficiency & retro-commissioning across labs and manufacturing

  In 2024 Gilead achieved 16.6M kWh in energy savings (107% of 15.5M kWh KPI) saving $1.8M. Programs include retro-commissioning (6.8M kWh), BMS optimization (4.8M kWh), facility optimization (3.4M kWh), HVAC optimization (1.3M kWh). Earned 2024 AEE International Award for Corporate Energy Management. Cork facility is ISO 50001 certified.

• Fleet electrification (EV100 commitment)

  Target: transition 100% of fleet vehicles to electric/low-emissions by 2030. As of 2024, 13% of global fleet is electric, with 58 EVs in U.S. fleet pilot, 626 charging points across 40 locations, and home-charging incentives offered in 10 countries for fleet EVs. Member of Climate Group EV100.

• Green building & sustainable lab design

  31 building certifications since 2016. New Foster City research facility targeting ILFI Zero Carbon certification with <500 kg CO2e/m² embodied carbon, 50% water savings, 85% C&D waste diversion. My Green Lab program has certified labs across 6 locations with 770+ scientists participating; three new lab certifications in 2024 (Santa Monica Platinum, Oceanside Green, El Segundo Green).

• Supply chain decarbonisation — supplier SBTi engagement

  Scope 3 represents 93% of Gilead's total GHG footprint. Gilead engages suppliers comprising top 75% of Scope 3 emissions: 38% have SBTi-approved targets and 16% have committed to set targets (54% total). New 2025 KPI: increase proportion of spend with SBTi-committed suppliers by 10% annually. Participation in Schneider Electric Energize Program for joint pharma renewables PPAs.

• Sustainable aviation fuel and business travel

  In 2024, use of sustainable aviation fuels (SAF) avoided 546 MT CO2e of emissions. SAF sourcing began in 2022 as part of business travel decarbonisation efforts.
