With regard to the use of sustainable resources, we concentrate on the use of electricity from renewable energy sources ("green electricity"), biogas and, wherever regionally tenable, rainwater. The share of green electricity used throughout the Group increased 3 % to 42 % (previous year: 39 %) in the reporting year. Due to prevailing circumstances, we were unable to reach our ambitious goal of increasing this number to 60 %. For this reason, the situation will be reassessed in the first half of 2013, at which time a new target timeframe will be set.
