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.

Regeneron sourced 52% of electricity consumption (129,883 MWh) from certified renewable sources in 2025. IOPS Ireland site uses 100% renewable electricity, with a new 650 kW rooftop solar PV array (1,600 PV modules) generating ~550 MWh annually. Sleepy Hollow site receives nearly 653,500 MWh of hydropower via New York State's Recharge NY initiative since 2022, plus 878,200 MWh from on-site solar — totaling 40% renewable electricity. In 2026, purchased RECs for first time to supplement generated/purchased renewable electricity. Accelerated 100% renewable electricity target from 2035 to 2030.

No narrative on durable removals approach in the firm's most recent reports.

• Energy efficiency upgrades at IOPS Ireland

  Three-phased approach based on 2024 ISO 50002:2024 climate action strategy study. Replacing fluorescent fittings with LED in administrative building (64% lighting energy reduction) and quality control building (61%), saving 596,060 kWh/year. Replaced fuel-powered lawn mowers with robotic battery-operated alternatives. At Tarrytown, GHG assessment identified measures during new facility design to reduce emissions by up to 1,896 MT CO2e/year.

• Product environmental footprint assessment

  Conducting product environmental footprint (PEF) for one medicine, with 2030 goal to complete PEFs for at least two products. Results will inform approach to reduce raw materials in production/packaging, energy, water and waste, optimize shipping/distribution, and design end-of-life device recycling — all while maintaining quality and safety standards.

• Sustainable lab operations & My Green Lab certification

  Four R&D labs earned My Green Lab Green certification (highest level), two earned Gold, and 10 are in recertification. Reduced paper use by >50% through digitization in IOPS. Diverted 99% of waste from landfill in 2025 with goal of zero waste-to-landfill for owned sites by 2030. Expanded Polycarbin lab consumables recycling from 9 to 11 labs (12,000+ lbs single-use plastics recycled); RightCycle Program recycled ~10 tons gloves at IOPS New York in 2025.

• Low-carbon transportation & EV charging infrastructure

  67 EV charging points at Ireland IOPS site, over 100 EV chargers across Westchester-area sites, 57 at IOPS New York sites. Intra- and inter-site shuttles at New York locations. Global commercial fleet includes electric and hybrid vehicle options. In 2025, partnered with supplier to introduce dedicated EV for distribution of lab consumables at IOPS Ireland — expanding to U.S. manufacturing sites in 2026.

• Supplier engagement on Scope 3 emissions

  Scope 3 emissions account for ~90% of total GHG inventory, driven by purchased goods and services (Category 1). Through CDP Supply Chain program, Regeneron engaged 51 suppliers to collect emissions data. In 2025, 22% of Scope 3 emissions calculated using supplier-specific data, up from 14% in 2022. 2030 goal: 75% of suppliers to have GHG emissions reduction targets for Scopes 1, 2 and 3.
