Our Approach to Sustainability
Sustainability Report
Built on Discipline, Driven by Continuous ImprovementAt EnerSys, sustainability is not a standalone initiative. It is embedded in how we operate, manage risk, allocate capital, and create long-term value. Our core values of accountability, continuous improvement, and operational excellence guide how we serve customers, support employees, and strengthen the communities where we operate. As a global provider of energy storage and power solutions, we recognise the important role we play in supporting critical infrastructure, industrial operations, transportation networks, and defence applications. We are focused on improving efficiency, reducing waste, managing resources responsibly, and building resilient operations that can adapt to changing market conditions and customer needs. |
U.S. DEPARTMENT OF ENERGY BETTER PLANTS PROGRAM
The U.S. Department of Energy’s Better Plants Program helps leading manufacturers boost their resilience and economic competitiveness by supporting improvements in energy efficiency. As part of the program, EnerSys has committed to reducing our energy intensity by 25% over the next ten years with 2020 as our baseline year.
In 2023, EnerSys won the Better Practice Award for the implementation of the EnerSys Operating System (EOS). EnerSys won the Better Project Award in 2024 for implementation of the cold-cube cutting process which significantly reduces emissions and lead exposure.

Our Stakeholders
CUSTOMERS & PARTNERS
As our customers and partners heighten their focus on sustainability, they are expressing a clear desire for their suppliers to follow suit. We understand that our products and services play a crucial role in helping our customers achieve their sustainability objectives, and we are committed to ensuring that our own operations reflect and support these goals.
EMPLOYEES
Employees are also deeply invested in the practices of their employers. Attracting and retaining top talent necessitates aligning with employees’ values and addressing their concerns regarding ESG matters. Similarly, we must extend the same consideration to the families, friends and neighbors within the communities where we operate and reside.
INVESTORS
Investors increasingly recognize companies that excel in ESG metrics as effectively managed and better equipped to navigate future operational, financial and regulatory landscapes. This includes addressing both short and long-term challenges related to climate change and the global shift towards a low-carbon economy.
SUPPLIERS
EnerSys works with more than seven thousand suppliers, sourcing goods and services from all over the world. In 2023, we sent out our first supplier ESG survey, working with our supply chain to begin the process of measuring and reporting on supply chain ESG topics.
REGULATORS
Regulators worldwide are also looking at new corporate requirements around ESG. As a New York Stock Exchange (NYSE) listed company, EnerSys complies with all corresponding U.S. Securities and Exchange Commission (SEC) requirements. The SEC announced its “Enhancement and Standardization of Climate-Related Disclosures for Investors’’ plan in 2022. While still a few years from required compliance for EnerSys, we are already preparing for this new regulation by aligning a portion of this 2023 Sustainability report with the EU Corporate Sustainability Reporting Directive (CSRD) and ESRS.
Enhancement & Standardization of Climate-Related Disclosures for Investors
EMPLOYEES
With nearly 10,000 employees worldwide, EnerSys sees its workforce as central to operational success and sustainability. Initiatives like business resource groups and employee training opportunities foster engagement and align workplace culture with corporate values.
SUPPLIERS
EnerSys works with around 5,000 suppliers worldwide and continues to embed sustainability into supplier evaluations. Through ongoing supplier engagement and our sustainability survey program, we are advancing responsible sourcing and improving transparency across our global supply chain.
COMMUNITIES
EnerSys actively engages with the communities where it operates through volunteering, local partnerships, and support for veterans and educational programs. These efforts reflect the company’s broader commitment to social impact and ethical business practices.
Materiality Assessment
In alignment with the EnerSys corporate sustainability strategy, we updated our materiality assessment in 2023 to meet double materiality standards, in which we identify and prioritize material risks, opportunities and potential external impacts. The assessment informs our sustainability reporting and disclosure efforts, ensuring that EnerSys reports on the issues most relevant to stakeholders and the business. EnerSys designed the 2023 assessment to engage the company‘s internal subject matter experts (SMEs) and delve into the environmental, social and governance topics that have the most significant bearing on our operations, stakeholders and the world.
MATERIAL TOPICS
As a result of our assessment, we identified 11 recurring themes related to impacts, risks and opportunities. The themes fall under multiple materiality topics. If new themes emerged, we incorporated them into the materiality topics covered in our 2021 Sustainability Report.3 We employed the following three-part process below.
