CORPORATE SOCIAL RESPONSIBILITY AND DECLARATION OF EXTRA-FINANCIAL PERFORMANCE

LIMITING OUR ENVIRONMENTAL IMPACT

By the end of 2018, priority 1 practices had been implemented by 100% of the Group’s R&D centers, in line with the target, and 94% of these teams had adopted priority 2 practices, against an end- 2018 target of 100%. Life cycle assessment (LCA) techniques that establish product environmental profiles (PEPs) are a powerful tool for designing better products. By challenging the usual technical solutions in the design and industrialization phases, the analysis of environmental impacts is also an excellent tool for innovation. The following are some examples of ecodesigned products launched by Legrand: W the Mosaic and Céliane user interface range: mechanisms used in the Mosaic and Céliane ranges of switches were reviewed in order to reduce the use of materials with high potential for depleting non-renewable natural resources. The resulting reduction was around 75%. This initiative also led to a significant reduction of some 15% in the amount of energy lost through heating when current is passed, which was achieved by changing the latching inside the switch. This reduction, extrapolated for all future production of these items, is expected to reduce environmental impact by some 57 metric tons of CO 2 equivalent; W the EDM range of transformers: a reduction in power dissipation resulted in a decrease in environmental impacts of approximately 30% compared with the previous generation of products. The PEP ecopassport ® issued for this series provides details of their environmental impacts. Moreover, the transformer generates less noise with this new design; W RX3 circuit breakers: the adoption of the ecodesign approach by the R&D team in India resulted in a range of circuit breakers that reduce the use of non-renewable natural resources and mitigate the impact of their manufacture and distribution; W “KALANK CS” recessed lights for drywall: the use of more efficient components with 40% less energy consumption and a new compact aluminum shell design made from 50% recycled aluminum have resulted in a more compact product that is easier to recycle. Overall, the environmental footprint has been reduced by around 40% for almost all environmental indicators; W the ecodesign approach also applies to packaging. It enables the ratio of packaging volume to product volume to be lowered. For instance, packaging experts have defined best practices that are

implemented by all R&D teams. These include using cardboard containing a high percentage of recycled material, printing with water-based inks, and using acrylic adhesives that emit fewer VOCs. In 2018, “Wrapeasy Universal Packaging” developed by Bticino won the “Oscar de l’emballage” award: improved use of materials sharply reduced the environmental impact of packaging used for the P31 cable tray range by more than 70% on average. R 4.5.2.4 2019-2021 CSR ROADMAP For its fourth CSR roadmap, due to be published in 2019, in connection with SDG9 (Industry, innovation and infrastructure) and SDG12 (Responsible consumption and production) Legrand is addressing the issue of innovating for a circular economy by adopting initiatives to: W integrate circular economy principles into the development of new products : To reduce the environmental impact of its products, Legrand integrates circular economy principles into its new product development. This ecodesign approach concerns all stages of the product life cycle. The Group also works to deal with waste arising from its manufacturing activities as effectively as possible. In 2004, Legrand also took early action to eliminate all substances covered by European directive no. 2002/95/EC on the Restriction of Hazardous Substances (RoHS). W provide environmental information on our products : Reducing the environmental impact of buildings also requires careful design choices. As a result, being able to inform users of the environmental impact of the products they are using is critical. The PEP ecopassport ® program, developed in France with Legrand’s support, provides a benchmark for measuring the environmental impact of electrical products. Product environmental profiles are now being supplemented by new environmental information programs. W make the most of our waste : Legrand also endeavors to limit the amount of waste generated by its industrial operations and is working on a waste treatment process that mitigates their negative externalities. This partly involves reusing waste in its production, and partly sharing best practice. It also involves identifying waste more accurately in order to sort it more effectively and eventually to make it easier to recycle or to give it a second life.
