The Together for Sustainability initiative was founded in 2011 by
BASF,
Bayer,
Evonik,
Henkel,
Lanxess, and
Solvay. The objective was to develop a global supplier engagement program and improve their own sustainability sourcing practices in line with the
United Nations Global Compact. Since January 2015, the TfS initiative is incorporated as an international non-profit association according to the Belgian law. Since June 2012, TfS conducts assessments and audits by independent experts, as well as the early partnership with the French company EcoVadis, which provided with sustainability scorecards and benchmarks. In June 2023, Jennifer Jewson, CPO of
LyondellBasell, was elected as president of the TfS. She was re-elected as TfS President in 2025 for a second term of 2 years. == Structure ==
