In 2020, we successfully finished implementing a sustainable water management system across all high water use sites, a process we started in 2016. At sites that consume large quantities of water and are also located in water-stressed areas, we reduced our water use by 27% relative to 2014, surpassing our original target of 10%.
Building on this success, in 2020 we developed a new set of goals for 2025 and 2030 aimed at enhancing the water efficiency of our processes and reducing the environmental impacts of our waste water. For instance, we defined an intensity score aimed at boosting water efficiency, which we intend to improve by 10% by 2025 (2019 baseline). Furthermore, it is our stated goal to exceed regulatory water-quality requirements. In an effort to minimize our negative environmental impacts, we plan to reduce potentially harmful emission residues in our waste water to below a scientifically defined threshold by 2030. In 2020, CDP gave our Water Security efforts a B rating (2019: B).
Water is not the only resource growing scarcer, which makes it imperative for us to use raw materials as efficiently as possible while simultaneously reducing our waste. We use a variety of methods for recycling, recovering and disposing of the waste we generate, each of which has a different impact on the environment. To systematically account for these effects, we have put in place the company Waste Score. We aim to reduce this score by 5% by 2025 compared with 2016. In order to support waste reduction, we are also constantly evaluating ways to enhance our production processes and waste disposal methods. By the end of 2020, we had achieved a 4.6% reduction.
