Business Supply Chain At PPG, we believe that achieving sustainability within our company is only part of the equation. We also must work to ensure our suppliers around the world are equally committed to sustainability as a core value. We expect our suppliers and their subcontractors to fully comply with all applicable laws and to adhere to internationally recognized environmental, social and governance standards. Our Global Code of Ethics, Supplier Sustainability Policy and Global Supplier Code of Conduct clearly state our expectations for every supplier. In 2015, we distributed a detailed questionnaire to our top 100 suppliers globally to assess their sustainability against our expectations. These suppliers represent approximately 25 percent of our annual procurement spend. Areas evaluated by the questionnaire included: Policies—Sustainability, code of conduct, anti-corruption and bribery, human rights, conflict minerals, proprietary technology, health and safety and environmental sustainability. Criminal violations involving corruption, bribery or antitrust. Spills, chemical releases and environmental contamination. Significant health and safety incidents and notices of violations. Citations or fines related to a breach of labor law. Process to educate, train and audit employees regarding company policies. Sustainability review processes to monitor corporate and supply chain performance. The majority of the evaluated suppliers scored favorably in the 2015 survey, and we are working collaboratively with the remaining to better align their sustainability culture with our expectations. Our Europe, Middle East and Africa region evaluates approximately 85 percent of its suppliers each year. While many areas evaluated pertain to sustainability, such as human rights and anti-corruption, the 2015 evaluation included specific sustainability performance indicators. In addition to helping suppliers evaluate and improve their sustainability performance, we seek their help in improving our own. Examples include asking suppliers to provide more environmentally friendly products, recycle packaging used to ship materials to our facilities and offer more fuel-efficient transportation services.

Supplier Diversity We believe that our company and communities benefit when we provide equal opportunities for diverse suppliers to compete for our business. As such, we actively seek small businesses and businesses owned by veterans, minorities and women that provide quality products and services at competitive prices.
