The U.S. Pharmacopeial Convention (USP) is a scientific nonprofit organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed, and consumed worldwide. These standards are recognized in the United States and more than 140 other countries, helping to ensure the quality of medicines and other health-related products.

USP's mission is to improve global health through public standards and related programs that help ensure the quality, safety, and benefit of medicines and foods. The organization collaborates with healthcare practitioners, manufacturers, and regulators to support the development of quality standards and to promote the safe and effective use of medicines.

In terms of sustainability, USP is committed to reducing its environmental impact and promoting sustainable practices. However, specific details about their sustainability initiatives, such as carbon footprint calculations or ESG reports, are not extensively documented in public resources. The organization may engage in sustainability efforts through its operational practices and partnerships, but further information would be needed to provide a comprehensive overview of their sustainability credentials.
