Reporting Overview PPG’s annual sustainability report underscores our commitment to transparent reporting on our economic, environmental and social performance. The report’s content is defined by our material issues, stakeholder expectations, business priorities and the requirements of the Global Reporting Initiative’s G4 Sustainability Reporting Guidelines (core option). We have attempted to be as accurate and inclusive as possible, with the information and data covering PPG locations and joint ventures around the world where we maintain at least 50 percent ownership. We currently do not seek assurance for our report, as the scale of our operations and the resources required are prohibitive. We will continue to explore assurance options as they evolve, but we are confident our internal processes provide sufficient oversight regarding the accuracy of the information we report. We encourage you to provide feedback on this report and our sustainability performance via email, a short online survey or a letter sent to PPG Industries, One PPG Place, Pittsburgh, PA 15272, Attention: Corporate Communications.
