Who We Are
Susta Oy is an expert company in corporate responsibility and sustainability systems, founded in 2019. We help companies and organizations develop, assess, and verify their sustainability — in a practical, clear, and human-centered way. Our goal is to make responsibility a natural part of everyday business, not a separate obligation or formality.
Sustainability is a company’s competitive advantage. It builds trust among customers, investors, and employees, while strengthening the organization’s reputation and long-term success. Susta Oy helps identify risks, clarify objectives, and build frameworks that integrate sustainability into strategy and daily operations.
Our services include sustainability project management, audits and verifications, as well as training and coaching across various industries. We have extensive experience with standards and systems such as ISO 9001, ISO 14001, ISO 45001, ResponsibleSteel, the Mining Responsibility System, and Suppliers’ Code of Conduct — assessments and verification are at the core of our expertise.
