Greenhouse Gas Emissions
Amphenol is acting to reduce our operational energy use and minimize our greenhouse gas (GHG) emissions through the application of lean production processes and capital investments in energy-saving equipment, which have allowed us to reduce our Scope 1 and 2 GHG emissions intensity. Our renewable energy strategy and GHG reduction efforts have led to a 36% decrease in our revenue-normalized Scope 1 and 2 (market-based) GHG emissions in 2025 compared to 2021. On an absolute basis, our GHG emissions have declined by 8% since 2021 and we remain on-track to achieve our goal to reduce our absolute Scope 1 and Scope 2 (market-based) GHG emissions by 10% by 2030 compared to our 2021 levels.
The use of renewable energy is an important part of our GHG emissions reduction strategy. Over the past few years, the renewable electricity portion of our total energy purchased has increased. We plan to further expand our use of renewable energy in our facilities as we work toward our goal of increasing our use of renewable energy to 50% by 2030.

Reducing our Carbon Footprint
Our global facilities continue to support our emissions reduction goals through proactive and innovative actions that reduce their environmental footprint and conserve resources, while at the same time helping our facilities save on energy costs. To support these goals, several Amphenol facilities have installed on-site solar panels to increase their renewable electricity consumption and decrease their dependency on fossil fuels. These installations have helped provide a continuous, stable and clean source of energy for their facilities. In addition, our successful solar installments at some facilities have inspired other Amphenol businesses to consider increasing their renewable energy consumption.
Water Use
Amphenol's manufacturing processes do not require a significant amount of water, however we do strive to be as responsible as possible with the water we use. In order to reduce our overall water usage, we pursue water optimization projects across our facilities and have invested in systems to reuse and reclaim our wastewater. Through our continued actions and investments, we were able to reduce our water withdrawal intensity by 21% in 2025 versus the prior year. Since 2021, our actions have resulted in our water withdrawal intensity declining by 36%, a 10% compound annual reduction over this four-year period.
We plan to continue to explore new opportunities for improvement in our water usage across our global footprint. To support our commitment, we have set a goal under SDG 6.4 Clean Water and Sanitation. By the end of 2030, Amphenol will reduce total water withdrawal of our top 20 facilities by 15% versus 2021 levels.

Limiting Our Water Use
Our team in Cerritos identified significant consumption in the facility's steel passivation process which utilizes fresh distilled water with strict quality parameters. Through a continuous improvement review, the team identified an existing wastewater recycling system at the facility that was underutilized. Engineers redesigned the system and installed an additional filtration stage using deionizing resin to achieve the required purity levels for the steel passivation process. The redesigned system was connected to the process, and following validation testing, the upgraded system successfully allowed water to be recycled, treated and reintroduced into the passivation process. This process improvement significantly reduced labor time, operational waste and the facility's demand for fresh distilled water.
Waste Disposal
Limiting our use of resources and minimizing our waste remain a core component of Amphenol's operational management culture. Our operations employ a number of methods to limit our waste, with some examples including utilizing recycled packaging for connectors, regrinding thermoplastics as appropriate to supplement virgin material feedstocks, composting organic material from our employee cafeterias and reducing our paper usage. As a result of our efforts, we were able to reuse, recycle or recover 68% of our total waste in 2025. We will continue to look for new ways to minimize our material use as we work to further reduce our waste production and deliver more sustainable products to our customers.

Reducing Raw Materials Use
As part of our environmental stewardship and sustainability initiatives, our Penang team actively manages waste generated from raw materials and production activities, including cartons, cardboard and plastic foam. Rather than sending these materials to landfills, the facility collaborates with a local organization which collects general waste from the site and carries out segregation and sorting activities. Beyond waste management, the initiative helps raise community awareness about the importance of recycling and upcycling. Encouraged by this effort, local residents also contribute by bringing recyclable items to the center, strengthening community participation and ownership. Through this initiative, the facility diverted 99 metric tons of waste and avoided 74 tons of CO2e emissions in 2025.
