A ctive Engagement and Dialogue We initiate and maintain conversations with relevant organizations, both internally and externally. We actively engage in standards development so our customers can assess our products and solutions using an unbiased and independent methodology. R euse, Reduce, Recycle We make these three intertwined behaviors a priority, by reusing when possible, reducing consumption when appropriate, and recycling at every opportunity. T angible and Continuous Improvement We set concrete goals and objectives that are crucial to measure progress. As we dialogue with our various stakeholders, including our Customers and Suppliers, it will be critical to show our ability to react to ideas and opportunities to improve our processes. We must listen with the intent to apply concepts and ideas which will move the yardsticks. H armonious product design which contributes to a sustainable planet We have an engineering legacy; it is in our DNA. The design of our products and solutions does not come by accident or happenstance – it is accomplished with a clear understanding of our Customers needs and a belief in the value of our Design for Environment attributes.
