We recognize that water is a finite, shared resource and we minimize water use in our facilities through conservation, innovation and reuse

Reduction in water intensity at priority sites in water scarce communities

We consider our impacts on the entire water basin, and take into account the local environmental, regulatory and socioeconomic context of each of our sites.

Our most significant impact on water availability in local communities comes from our facilities located in water stressed communities. When setting our 2030 water goal, we chose to prioritize water efficiency measures in areas with high water scarcity risk rather than reducing our overall water intensity.

We focused our efforts in 2023 on 26 PPG facilities that were identified for high water use and proximity to water stressed regions. We invested in submeters to measure the water used for different production processes rather than relying on facility-level water meters. These submeters helped us to identify the most water-intensive production processes so we could develop strategies to reduce our usage. The detailed view of our water usage also helped identify water lines in need of repair or replacement, which helped reduce water waste.

Combined, these strategies have helped reduce the amount of water that we use in water stressed communities by 13% from a 2019 baseline. We are continuing to broaden our focus, evaluating more of our facilities in water stressed areas and building on our progress to date. Given our rapid progress toward meeting the 2030 goal, we are exploring the possibility of setting a more ambitious water reduction target in the future.

Zero Discharge Project

During our production processes, some paint gets left behind in the tanks and pipes we use to mix and package our products. We clean out the system with water to keep it running properly and avoid cross contamination between batches. Historically, we have sent pretreated wash water to a municipal water treatment facility to be further cleaned and then released back into the local water system. The Zero Discharge Project is an ongoing initiative which aims to reuse wash water and reduce raw material waste. In 2023 alone, we were able to reuse approximately 16 million pounds of water in our U.S. and Canada architectural coatings business, an increase of 615,000 pounds, or 4%, over the previous year.

Reuse of wash water may be limited by a range of factors, including local legislation that limits certain material use and physical constraints on the amount of water that can be stored for reuse at our production facilities. In 2023, we implemented an optimization process to consider these factors and expand the reuse of wash water and recovery of raw materials from the Zero Discharge Project. We expect that this process will enable us to reuse as much as 10% more water in 2024.

Leak detection in Caivano, Italy

As climate change increases the frequency and severity of droughts, many countries have responded by instituting water rationing measures. We focus our investments to ensure we're abiding by local regulation and using water efficiently, particularly in water stressed areas.

The PPG site in Caivano, Italy, responded to local water stress by installing water monitoring systems to identify leaks in the facility. The operations team found underground leaks in the sanitary water system and fire water storage tank which had previously gone unnoticed. By repairing the leaks and stopping water losses, we reduced monthly water use at the site by more than 60%. The repairs are projected to reduce water use at the site by 210,000 m3 per year and save PPG more than €200,000.

The operations team at our Caivano site continues to reduce the amount of water withdrawn from the municipal water supply through a combination of repairs, refurbishments and process improvements. The long-term goal for the Caivano site is to reduce water use by 90% from a 2022 baseline.
