Verbund – unique competitive advantage Actively managed in line with market requirements Geismar Nanjing Antwerp Ludwigshafen Freeport Kuantan . Combined heat and power plants Synergies and integrated energy in logistics and >€1 billion Verbundprevented infrastructure, 6.5 million tons of cost savings of CO emissions minimization of per year 2 waste in 2017 8

Waste management BASF Verbundhelps to prevent and reduce waste Global waste volume 2017 Waste is managed based on the following hierarchy: (million tons) 1. Avoid Recycled or Incinerated or 2. Reuse thermally recovered 2.1 disposed of 3. Recycle 0.8 1.3 4. Energy recovery (e.g., waste-to-energy incineration) 5. Other incineration 6. Disposal such as surface or underground landfills 9

Resource efficiency Responsible use of carbon sources  We are committed to resource efficiency and climate protection  BASF uses carbon raw materials responsibly: 82% of carbon converted to products, 17% consumed for process energy and converted to CO , 1% waste1 2  Comparisons with European emissions trading benchmarks show that our chemical plants operate at above-average energy efficiency  23 million tons of CO emissions by BASF worldwide in 2017 2 compared to 10–30 million tons p.a. for one coal-fired power plant  Customers’ use of BASF’s climate protection products sold in 2017 avoided 570 million tons of CO2 equivalents (thereof 6% attributable to BASF)2  In 2017, BASF achieved CDP leadership status once again 1 BASF carbon massbalance calculation (2017, non-audited) 2 Based on the chemical industry standard of the International Council of Chemical Associations (ICCA) and the World Business Council for Sustainable Development (WBCSD) 10
