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.

In the new 2030 goals, Regeneron accelerated its goal to match 100% of electricity consumption with certified renewable sources by five years — from 2035 to 2030.
sustainability_report p.54
New 2030 goals introduced: reduce combined Scope 1 and 2 GHG emissions by 15%; 75% of suppliers to have GHG reduction targets for Scopes 1, 2 and 3; 100% renewable electricity by 2030 (accelerated from 2035); zero waste-to-landfill for owned sites; divert 50% of nonhazardous waste; develop water mass balance; conduct PEFs for at least two products.
sustainability_report p.11
In 2024 and 2025 Regeneron began disclosing Scope 3 Category 4 (Upstream Transportation and Distribution) emissions; no prior-year data shown for 2021-2023.
sustainability_report p.69
Regeneron's 2025 responsibility goals align with five UN Sustainable Development Goals: SDG 3 (Good Health and Well-Being), SDG 4 (Quality Education), SDG 5 (Gender Equality), SDG 12 (Responsible Consumption and Production), SDG 17 (Partnerships for the Goals).
sustainability_report p.64
Limited assurance from ERM CVS for GHG emissions, energy, water, waste, health and safety, and STEM programming data using ISAE 3000 (Revised).
sustainability_report p.61
Total water usage data from 2021 to 2023 has been restated, reflecting methodological changes. Scope 1 and Scope 2 (market-based) emissions intensity revised for 2020-2022 to account for updated square meters.
sustainability_report p.69
Achieved 2025 target to match 50% of electricity consumption with certified renewable energy sources (52% in 2025); achieved 46% reduction in combined Scope 1+2 (market-based) GHG emissions per square meter vs. 2016 baseline, surpassing 30% goal.
sustainability_report p.66
Received LEED Gold certification for on-site day care facility in Tarrytown; fully electric building with 145 kW rooftop solar array.
sustainability_report p.52
2030 goal to develop water mass balance to advance water resource management. Regeneron also assessed water stress across operations using WRI Aqueduct Water Risk Atlas.
sustainability_report p.58
In 2025 Regeneron began to assess nature-related dependencies, impacts, risks and opportunities. Findings will inform approach to nature and biodiversity.
sustainability_report p.59
Aim to achieve zero waste-to-landfill for owned sites and divert 50% of nonhazardous waste to recycling, beneficial reuse and composting by 2030. Also conducting Product Environmental Footprints for at least two products by 2030.
sustainability_report p.11
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.
sustainability_report p.59
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.
sustainability_report p.53
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.
sustainability_report p.54
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.
sustainability_report p.55
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.
sustainability_report p.54
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.

2023· 1 event
Regeneron did not set the previously committed science-based targets for Scope 1 and 2 by 2023 due to rapid growth and evolving landscape. Replaced with new 2030 target of 15% absolute reduction in combined Scope 1+2.
