As a top energy storage manufacturer, we understand our operational impact on the environment and climate. We take our responsibility seriously, striving to minimize our ecological footprint while assisting our customers in reaching their climate objectives through high-quality energy storage products and services. To that end, we are committed to improving the efficiency of our operations, reducing waste, managing water responsibly, and investigating the use of renewable energy as we strive to reduce our environmental impact and protect valuable natural resources. |
Climate and Greenhouse Gas Emissions
We are actively seeking to reduce our direct and indirect GHG emissions by increasing the efficiency of our operations and exploring renewable energy sources for our facilities. In 2023, we continued to measure and report our energy consumption and the associated Scope 1 & 2 emissions.
In 2023, we decreased our Scope 1 emissions 4.2% from 2022, showing a 25% reduction since 2019. Our Scope 2 emissions increased by 2.1% from 2022 to 2023, as a result of increased electrification. Nevertheless, we expect a long-term decrease as the grid decarbonizes with support from renewables and energy storage – in part, produced by EnerSys. Additionally, we completed our first Scope 3 emissions inventory, providing insights into our supply chain and overall carbon footprint.

Emissions down 4.2% since 2022, and down 25% since 2019.
Emissions up 2.1% since 2022, and down 3.4% since 2021. We expect a long-term decrease as the grid decarbonizes.
We have disclosed Scope 3 emissions for 2022 and 2023.
In 2023 EnerSys took the next step in our sustainability journey by quantifying Scope 3 emissions associated with our upstream and downstream activities, establishing 2022 as the baseline year. Scope 3 GHG emissions account for the footprint from activities associated with our business, but over which we don’t have direct control, such as sourcing materials, product shipping, business travel, employee commute, and the emissions associated with the use of our products – which vary greatly depending on how clean the electricity is where a battery gets used. Like many manufacturing companies, Scope 3 emissions far surpass our direct Scope 1 and Scope 2 emissions. Between 2022 and 2023 our total Scope 3 emissions decreased by 2.5%. Over the next few years, we will continue to explore strategic and cost-effective ways to reduce emissions throughout our supply chain.

New Technologies Improve Energy Efficiency in Bielsko, Poland
The EnerSys Bielsko-Biała factory is one of Europe’s largest traction battery plants producing over 2.2 million 2V cells per year for the European, Asian and Australian markets. Capitalizing on the emergence of new technologies, the operations team in Bielsko- Biała upgraded the insulation in lead pots in the manufacturing process, saving the factory an estimated 367 megawatt hours (MWh) per year. The savings from this efficiency upgrade is roughly equivalent to running an average American home for over 36 years. Teams across all EnerSys facilities are consistently looking to make improvements and find efficiency opportunities.
Water
Water is a vital resource to all life, and EnerSys is committed to being a good water steward everywhere we do business. Water plays a crucial role in our manufacturing operations and is used for multiple processes, including preparing electrolytes, plate manufacturing, battery formation and washing finished production equipment and manufacturing areas. It is imperative that we drive efficiency in our operations, reduce our freshwater usage and reuse water wherever possible to minimize our impact on the environment.
In 2023, we continued to monitor and disclose the quantity of water withdrawn from our manufacturing facilities. In 2023, our operations utilized 892 megaliters, marking an absolute reduction of 9.7% from 2022. We prioritize using recycled water over fresh water whenever feasible, with our recycled water usage at 12% in 2023. Furthermore, we are committed to minimizing wastewater discharge from our operations, and we consistently maintain chemical and total dissolved solids levels well below regulatory requirements.
2030 WATER GOAL & PROGRESS
We are committed to reducing our water intensity per kWh of storage produced by 25% by 2030.
We have achieved a 6% improvement since 2020.

Tijuana Mexico Plant
As part of our commitment to the UN CEO Water Mandate, EnerSys is engaging in water reduction and reuse projects in water-stressed regions, like in Tijuana, and we are logging our progress in the UNGC’s Water Action Hub. Tijuana is a state where water resources are often strained as water shutoffs are increasingly common and key reservoirs are nearing all-time lows.15 The team in Tijuana implemented a water reuse project at the plant which is estimated to have reduced the plant’s city water usage by about 4,400 gallons of water per day. That’s enough water to provide more than 5,200 people with the recommended amount of daily drinking water, 3.2 Liters per day.

Waste
As a global leader in manufacturing energy storage and energy systems, we have an obligation to manage and reduce the waste materials we produce responsibly. Non-hazardous and hazardous waste must be handled carefully across our products’ value chain to promote safe operations and protect human health and the environment. This focus on reducing and eliminating waste also makes good business sense, as it allows us to identify opportunities for reusing products and reducing waste disposal costs.
Waste generation, handling and disposal are managed at the facility levels based on the type of operation and applicable regulatory requirements. We track all waste materials with the paperwork required by regulation to appropriately account for our impact. Where appropriate, we employ expert third-party contractors to manage our waste responsibly.
In 2023, we began the process of performing waste characterization analysis at a select number of facilities. This analysis will allow us to better understand the waste we produce and how it is managed. We will set a waste reduction target when these studies are complete and we have sufficient data to set an appropriate and achievable target.
