Our values drive our approach

At EnerSys, sustainability, reliability, and resilience are core to our values and embodied in our daily operations. Our products address global challenges such as climate change, decarbonization, efficient goods distribution, grid reliability, telecommunications, and innovation. Our batteries and energy storage solutions contribute to a resilient, low-carbon future.


Our sustainability policies underscore our unwavering dedication to excellence in managing environmental, social and governance (ESG) issues, encompassing not only our internal operations but also extending throughout our supply chain. These standards apply to every employee, contractor, operating unit, vendor and supplier within the organization, and the Board and senior executive team oversee compliance. Our policies serve as the compass for shaping our strategy and programs, ensuring a perpetual cycle of monitoring and enhancing our performance. Our policies undergo thorough annual reviews conducted by subject matter experts (SMEs), ensuring relevance and accuracy, and updates are implemented as necessary. Our sustainability policies can be seen here.

“Sustainability is part of who we are at EnerSys, it’s something that all of our stakeholders – investors, customers and employees – care about and want to see more of.”

Our Sustainability Goals & Commitments


Alignment With SDGs


The United Nations Global Compact (UNGC) is a call to companies to align their business strategies and operations with ten universal principles on human rights, labor, the environment and more, and to take actions to advance societal goals. More than 20,000 companies in 167 countries participate in the Compact, including EnerSys. Our corporate policies adhere to the UNGC. Our corporate policies and actions adhere to the UNGC’s 10 Principles.



The 2030 Agenda for Sustainable Development, embraced by United Nations (UN) member states in 2015, outlines a global plan for peace, prosperity, and sustainability for current and future generations. Central to this agenda are the 17 SDGs, urging global action across developed and developing nations to address climate change, eliminate poverty, enhance health and education, reduce inequalities, and promote economic growth.

EnerSys is dedicated to advancing the SDGs, aiming to make a positive impact through our products, operations, community involvement, and workplace. We are focused on contributing significantly to the top three SDGs where we believe our impact is most substantial:


  • SDG 7: Affordable and Clean Energy
  • SDG 10: Reduced Inequalities
  • SDG 13: Climate Action

We aim to leverage the UNGC and the SDGs to further the transition to a low-carbon, clean energy future everywhere, for everyone. Throughout this report, we have indicated where our actions and metrics align with specific SDG targets.

Our Stakeholders


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.


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.
