Regeneron

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.

In 2025 52% of Regeneron's electricity consumption (129,883 MWh) came from certified renewable sources. IOPS Ireland site uses 100% renewable electricity, with a new 650 kW rooftop solar PV array (1,600 modules, ~550 MWh/year) commissioned in 2025. Since 2022 Regeneron has participated in New York State's Recharge NY initiative, receiving nearly 653,500 MWh of hydropower at Sleepy Hollow plus 878,200 MWh on-site solar (40% renewable at that site). In 2026 Regeneron purchased Renewable Energy Certificates (RECs) for the first time to supplement generated/purchased renewables and meet the 2025 target. The 100% renewable electricity goal has been accelerated from 2035 to 2030.

Regeneron does not disclose use of durable carbon removals (DAC, BECCS, biochar) or carbon offset retirements. The strategy emphasizes absolute reduction (15% Scope 1+2 by 2030), supplier engagement (75% of suppliers to have GHG targets), and on-site biodiversity/ecosystem restoration through the BeaCON program (apiaries, wildflower meadows, invasive species removal). Composting (food waste increased 74% YoY in 2025) and waste-to-energy displace landfill methane but are not framed as removals.

• Waste reduction and circularity in labs (My Green Lab, RightCycle, Polycarbin)

  99% of waste diverted from landfill in 2025. Partnerships with Polycarbin (12,000+ lbs hard-to-recycle plastics, 2,000+ lbs nitrile gloves recycled), RightCycle (~10 tons gloves recycled at IOPS NY in 2025, 28 tons cumulative since 2022). 4 labs earned Green My Green Lab certification, 2 Gold, 10 in recertification. Sodium hydroxide/ethanol recategorization at IOPS NY reduced hazardous waste by 150 tons since July 2025, with 300+ tons expected annually.

• Energy efficiency in labs and manufacturing facilities

  IOPS Ireland implemented a three-phased energy efficiency program (informed by 2024 ISO 50002:2024 audit) including LED lighting retrofit expected to cut administrative building lighting energy by 64% (596,060 kWh/year), and replacement of fuel-powered lawn mowers with electric robotic units. Central energy management system with submetering at IOPS New York and Ireland. GHG assessment of new Tarrytown facility identified design measures to reduce up to 1,896 tCO2e/year.

• On-site renewable electricity generation

  On-site solar PV (650 kW array at IOPS Ireland with 1,600 modules producing ~550 MWh annually; rooftop solar at Sleepy Hollow contributing 878,200 MWh) reduces grid dependency. Combined with hydropower via NY Recharge NY program, Regeneron generates significant on-site renewable electricity, supplemented in 2026 with REC purchases.

• Employee commuting reduction via shuttles and EV infrastructure

  Scope 3 Category 7 (employee commuting) was 32,950 tCO2e in 2025. Mitigation includes intra/inter-site shuttles at NY locations, commuter shuttles in Westchester, rideshare portal, bike storage and >200 EV charging points across global sites.

• Supplier engagement on Scope 3 emissions (Cat 1 = ~90% of footprint)

  Scope 3 represents ~90% of total GHG inventory, dominated by purchased goods and services (Category 1, 870,010 tCO2e in 2025). Regeneron participates in CDP Supply Chain program; 22% of Scope 3 emissions calculated using supplier-specific data in 2025 (up from 14% in 2022). 2030 goal: ensure 75% of suppliers have GHG reduction targets covering Scopes 1, 2 and 3. Refreshed Supplier Code of Conduct and Sustainable Procurement strategy in 2025.

• Low-carbon logistics and EV fleet for distribution

  Partnered with supplier to introduce dedicated EV for lab consumables distribution at IOPS Ireland in 2025, expanding to U.S. manufacturing sites in 2026. Global commercial fleet includes electric and hybrid vehicles. 67 EV charging points at Ireland, >100 across Westchester sites, 57 across IOPS NY sites. Reuse of plastic totes replaces 8,704 lbs of cardboard packaging.
