EnerSys® Sustainability Update 2022

Environmental Data

In May of 2023, EnerSys published its 2022 Sustainability Update. Aligned with internationally recognized reporting standards noted in the Sustainability Report, this document is intended as an addendum, providing quantitative information covering the calendar years, 2019, 2020, 2021 and 2022.

The table below presents key environmental data covering EnerSys globally. The scope includes manufacturing, warehouse, service and distribution centers, offices and other facilities, both owned and leased, totaling around 180 locations.

The data was gathered by the EnerSys Sustainability Team utilizing the NAVEX ESG™ Environmental, Social and Governance global platform. Greenhouse gas data covers Scope 1 (direct) and Scope 2 (indirect) emissions. Data is based on utility data with measurements.

Global warming potential and emissions factor conversations are based on the latest guidance from:

  • International Energy Agency (IEA)
  • The Climate Registry -DEFRA
  • IPCC Fourth Assessment Report (AR4 -100 year)

When utility, supplier, customer or other data were not available, estimates were made in alignment with the Greenhouse Gas Protocol and ISO1464-1 guidance.

Aligned with our vision: "Powering the Future - Everywhere for Everyone," EnerSys intends to provide ongoing updates and increasingly comprehensive sustainability reporting and disclosure aligned with the expectations of our stakeholders.

  1. Figures in the table below have been rounded and may therefore not fully align
  2. Includes electricity, natural gas, propane, coal and other petroleum fuels.
  3. Whereas EnerSys does not specifically contract renewable electricity, this figure does not account for the percentage of renewable electricity that is de facto part of the total electricity consumed across various geographies as part of the grid. It is, however, accounted for in the total Scope 2 greenhouse gas emissions.
  4. Reduction is due to solar array coming temporarily offline in our Bellingham location and now 100% of Brazil location purchased electricity generated via hydroelectric
  5. Certified as Hydroelectric power in Brazil
  6. An assessment to begin measuring Scope 3 supply chain emissions is currently underway
  7. This is an estimate based on Greenhouse Gas Protocol and ISO-14064-1 with a confidence interval of +/- 15%
  8. Pb emitted to the atmosphere per year
  9. Shipped for disposal
  10. Increase due to 1-off remediation in Richmond, KY property
  11. Water is consumed in products as well as through evaporation. Like for like data not available for 2019
  12. As a percentage of discharged water. Note that a significant percentage of water recycling takes place in our Chongqing, China plant which includes cycling water in cooling towers
