Our TripleS (Sustainable Solution Steering) is based on the internationally aligned method Portfolio Sustainability Assessment (PSA) by the World Business Council for Sustainable Development (WBCSD) and is an international recognized method for sustainability assessments for BASF’s global portfolio. TripleS assesses whether a product meets BASF’s internal as well as regulatory, customer-specific, and social requirements and how it compares to market standard solutions in nine sustainability categories. Products that are being identified as likely affected by a sustainability issue will be classified as «monitored» or «challenged». Challenged solutions will be phased out within five years.
