Clariant’s Portfolio Value Program is a systematic approach to consistently evaluate the entire product portfolio utilizing sustainability viewpoints. It can be done with an absolute observation (»How sustainable is a product really?«) as well as with a relative observation (»How sustainable is a product compared to similar products on the market?«). The result of this analysis gives indications of the nature and extent of the necessary improvements in order to continuously optimize the entire product portfolio. On the basis of 36 criteria in the categories of environment, society and economy, the portfolio’s products are being examined throughout their entire life-cycle to assess their strengths and weaknesses in reference to sustainability. Subsequently it becomes clear, which products already fulfil Clariant’s sustainability standard and which of them have potential for improvement. Based on the results, Business Units define their individual improvement roadmaps and prioritize measures to optimize the sustainability of their product portfolios.
