Solutions for Reducing your GHG Footprint Dr. Andree Blesgen 6/23/2016

How Evonik approaches the topic of Sustainability Three Levers to Sustainability Measure & communicate Life Cycle Assessments, Carbon Footprint Estimations, SusCHEQs, Evonik Carbon Footprint Optimize processes Reduce energy and water consumption, decrease waste water and solid waste generation, close raw material cycles High quality products Long life time, more with less, recycle products, Design for Sustainability

Our Supply Chain is important – and Evonik is part of someone else‘s supply chain Evonik Carbon Footprint 25.7 million metric tons total CO2e emissions 5.9 million metric tons direct CO2e emissions Typical distribution for the chemical sector About 30 % of emissions (Scope 1 and 2) can directly be influenced MM mt CO2 equivalents

We are optimizing our gate-to-gate processes Some Examples for Optimized Processes Recovery and re-use Raw material, intermediate, and product recovery from waste streams Organic solvent recovery Highest standards in waste treatment Anaerobic processes for energy recovery Compliance to very strict discharge limits Safe in-house incineration of solid wastes Energy- and raw material-efficient, high-yield processes Top catalysts, high yields, low losses Continuous improvement processes, e.g. Environmental Technology Excellence
