We carefully select suppliers that share our commitment to continuous operational improvement, creating competitive, sustainable advantages within our supply chain.

In 2025, we invested over $7.9 billion with more than 32,000 suppliers globally to procure raw materials, indirect goods and services and transportation. Approximately 96% of greenhouse gas emissions associated with PPG's business are in the value chain, so we understand the criticality of working with supplier and customer partners. We have prioritized work with a selection of key suppliers that represent the majority of our upstream scope 3 emissions. Learn more in the energy and emissions section.
We work with suppliers to understand their current practices and innovate products and processes that use less energy, produce less waste and avoid negative health impacts on people throughout our value chain. By the end of 2025, we assessed 2,060 suppliers, representing 66% of our spend, against sustainability and social responsibility criteria across environmental, labor and human rights, ethics and sustainable procurement practices. The assessment process covered 100% of PPG's key suppliers.
Sourcing sustainable feedstocks
PPG understands that sustainable procurement is a key enabler for the development of more sustainable products. We collaborate with suppliers to measure and certify the environmental impacts of raw materials and advance innovation in areas such as material recycling and bio-based alternatives. In 2025, several PPG sites in Europe achieved REDCert2 certification, enhancing our ability to source sustainable feedstocks with robust chain-of-custody traceability and more reliable impact measurement. Our procurement and technical teams work closely with suppliers to pass certifications through the value chain, including providing documentation, conducting site audits and validating carbon accounting. We continue to pilot these approaches in regions with strong customer demand and regulatory alignment, particularly in Europe. This allows us to explore using lower carbon and bio-based raw materials that match the performance of existing inputs while helping customers address evolving expectations around product carbon footprints and transparency.
Evaluating supplier practices
Our procurement team continues to strengthen its approach to identifying improvement opportunities in our supply chain. We apply a risk-based approach to supply chain management and focus on the industries and geographies most likely to have issues. PPG uses an external supplier screening tool to help us understand where sustainability risks are concentrated along our supply chain. In 2025, we more than doubled the number of suppliers using this tool, while maintaining clear performance expectations, including a minimum score across key sustainability categories. As a result of our ongoing engagement efforts, fewer than 5% of suppliers now fall below this threshold.
To drive continuous improvement, our procurement team works with suppliers to implement corrective action plans based on any deficiencies identified through our digital screening tool or supplier audits. Once corrective action plans are established, category managers are responsible for monitoring implementation and tracking performance improvements. This systematic approach continues to drive strong results, as evidenced by a significant year-over-year improvement in PPG's overall score from our external supplier screening tool. This in turn creates a competitive advantage for PPG through lower carbon footprint product formulations compared to our peers.
Recognizing responsible vendors
Every year, we recognize suppliers for responsible business practices that exceed our expectations with the Excellent Supplier Awards in different categories. Our procurement, business and functional teams evaluate and award suppliers based on competitive advantage and value, as well as a range of sustainability factors. Award recipients must:
- Demonstrate world-class sustainability practices
- Innovate and develop new products requiring less intensive material and energy consumption, and
- Leverage their strengths to support PPG’s sustainability goals.
There was one sustainability award recipient in 2025.
