CO2 performance

As we care about the environment, as much as we like to work with everything that’s got to do with water, we have implemented the CO2 Performance Ladder program. With several levels to complete, we choose not to start with the easiest. We introduced the program at level 3, and given ourselfs the duty to have a 5% decrease in our CO2 output by 2021, compared with 2017. DNV certifies Muller meets the requirements of CO2 Performance ladder version 3.0
