Sps Conference Essen 2009 Basf Mock Knoblauch

  1. 1. How to Assess the Sustainability of Products? C. Mock-Knoblauch, BASF SE 28.9.2009
  2. 2. Sustainable Development is based on three Pill th Pillars How to measure the Society sustainability performance of a good or service?  holistic Ecology  scientific, objective  cost effective Economy  decision oriented => BASF’s eco-efficiency analysis
  3. 3. Life Cycle Assessment (LCA): From cradle to grave Output Production P d ti Use U Disposal Di l Products intermediates Landfill Extraction f E t ti of raw materials Incineration Energy production Input
  4. 4. Sustainability assessment of Biodiesel f Bi di l State f th St t of the art: t  Although biodiesel is made from renewable raw materials, the environmental advantages are small g  The production of biodiesel is more expensive than that of conventional fossil diesel (excl. taxes and subsidies)  However, biodiesel production creates jobs in the agriculture sector. customer benefit alternatives Use of a conventional •RME (biodiesel) diesel car (driving distance 200.000 km) ) •conventional diesel
