Environment: Stewardship of Planet & Resources

In FY26, EnerSys continued to enhance our fiscal-year-aligned Scope 3 greenhouse gas inventory, further refining our data sources, methodologies, and assumptions across key emissions categories. Scope 3 emissions represent activities beyond our direct operational control, including purchased goods and services, transportation, business travel, employee commuting, and the use-phase of our products. As with many manufacturers, Scope 3 emissions remain significantly greater than our direct Scope 1 and 2 emissions. Ongoing improvements to our inventory - including updated emissions factors, more comprehensive transportation data, and refined procurement categorization - provide greater visibility into our value chain and support informed decisions that improve operational efficiency, strengthen supply chain performance, and create long-term value.

Investing in Operational Excellence 

In 2023, EnerSys established the Green Revolving Fund through its Climate Action Plan Roadmap to accelerate investments in projects that improve energy efficiency, reduce greenhouse gas emissions, and strengthen operational performance. By reinvesting the savings generated by completed projects into future initiatives, the fund creates a self-sustaining approach to continuous improvement. Since its establishment, the Green Revolving Fund has supported several projects, including:

Strengthening Energy Resilience in France

In FY26, EnerSys secured a renewable Power Purchase Agreement to supply approximately 20 GWh of wind-generated electricity annually from two wind farms in France to our Arras manufacturing facility. The agreement enhances energy supply security, provides greater long-term cost visibility, and supports our strategy to improve operational efficiency. During the first quarter, renewable energy supplied 57% of the site's electricity demand, reducing greenhouse gas emissions by approximately 148 metric tons of CO₂ while strengthening the resilience of our operations.

Energy is essential to our operations, and we are continuously pursuing ways to operate more efficiently and reduce consumption. Improving energy performance not only minimizes our operational impact but also drives cost savings and performance gains. Across our manufacturing network and supply chain, we prioritize energy-efficient technologies and actively seek innovative methods to optimize usage and maximize value.

2030 ENERGY GOAL & PROGRESS

We are committed to reducing our energy intensity per kWh produced by 25% by FY30 compared to FY21. 

We have achieved a 21% improvement since FY21

* Per U.S. Department of Energy guidelines, this goal is focused on 5 U.S. factories: Richmond, Warrensburg, Hays, Springfield 1 and Springfield 2. It does not include all EnerSys facilities.

Expanding Our Solar Energy Portfolio

EnerSys continues to expand its portfolio of on-site solar generation to support more efficient and resilient operations. The Newport installations generated approximately 80 MWh during FY26. The recently completed WMA solar project is designed to contribute additional generation in future reporting periods.

Approximately 50 MWh of this renewable electricity was used to charge electric vehicles on site. The Newport installations complement a growing portfolio of renewable energy projects across EnerSys, including the solar array at our Bellingham facility, which generates approximately 5 MWh annually, and our 6.1-acre solar array at our global headquarters in Reading, Pennsylvania, designed with an estimated annual generation capacity of approximately 7.3 GWh, subject to operating conditions. Together, these investments strengthen operational resilience, improve energy efficiency, and support our long-term energy strategy.

Water

In FY26, total water usage at EnerSys decreased to 915 megaliters, approximately 16% lower than FY22 and 5.7% lower than FY20, reflecting lower overall water consumption compared to the previous year. Changes in production volumes and the mix of battery chemistries manufactured continued to influence overall water demand, as different products require varying levels of water throughout the manufacturing process. We continue to prioritize responsible water management across all operations, with particular attention to facilities located in regions facing water stress or other critical constraints. Through ongoing investments in water reuse, recycling, and conservation initiatives, we remain focused on strengthening our long-term approach to efficient and responsible resource management.

2030 WATER GOAL & PROGRESS

We are committed to reducing our water intensity per kWh of storage produced by 25% by FY30.

We have achieved a 6% improvement since FY21

* Although water intensity increased slightly from FY25 to FY26 due to changes in the product mix and external factors such as weather and climate variability, the overall trend since the FY21 baseline reflects continued improvement in water intensity through ongoing operational efficiency and water management initiatives.

Recognizing Excellence in Water Stewardship

In 2025, EnerSys' Missouri manufacturing facilities were recognized by the Missouri Water Environment Association (MWEA) for outstanding wastewater management and regulatory compliance. Warrensburg received Platinum and Gold Awards, Springfield Plant 1 earned a Gold Award, and Springfield Plant 2 received a Silver Award. These recognitions reflect the dedication of our local teams to maintaining high environmental standards and responsible water management across our operations.
