HAHN+KOLB relies on modern and sustainable construction for its own facility management, making it possible to generate power while protecting resources. The photovoltaic system with a maximum capacity of 87 kWp on the south side of the corporate headquarters generates up to 88,000 kWh of electricity per year. Not only does the company use regenerative electricity, it has also reduced its annual heating needs considerably by using a heat pump. In the warm summer months, this helps cool the building. Native plants cover 1,400 m2 of the green roof, thus compensating in part for sealed surfaces. In addition, the outdoor area has been recultivated while preserving the old trees. Nesting boxes and insect hotels enrich the biodiversity on the company premises and serve to protect local species. HAHN+KOLB was honored by the “UN Decade on Biodiversity 2019” for its efforts.

As a traditional sales company, many of the employees at Würth Norge AS spend a great deal of time on the road. Because of this, the company is ideally positioned to make use of alternative drives to drastically reduce its greenhouse gas emissions. Würth Norge AS is leading by example by transitioning to electromobility. Charging stations have already been set up for the employees at the headquarters. In 2022, charging stations were installed at several pick-up shops, and more will follow so that customers can charge their electric vehicles there while they shop. In addition, the company has started to install super chargers, which were available from first quarter of 2023 and which is powered in part by solar panels on the roof of the warehouse. Würth Norge AS plans to replace 100 % of its company and service vehicles with emission-free vehicles by 2030. At the end of 2024, 50 % of all company vehicles were already electric or hybrid. When renewing future leases, employees will be required to opt for electric or non-emission vehicles.

Würth Spain procures 100 % of the power it requires for its headquarters and pick-up shops from renewable and thus green energy sources. At the location in Agoncillo, 2,650 photovoltaic modules with a maximum total output of 1,200 kWp provide 37 % of the electricity required there. In order to bolster the in-house power supply, 50 photovoltaic modules were installed at the Palau location in 2022, with a nominal output of 22.5 kilowatts. Aerothermal energy is also used there to heat the water using a heat pump to exchange heat with the outside air and thus generate warm water throughout the entire year. Furthermore, Würth Spain has a contract with an energy provider guaranteeing that 100 % of the additional electricity required is generated from renewable energy sources. At the beginning of 2025, the installation of 1017 photovoltaic panels with a peak power of 442kW and a nominal power of 500kW is planned at the Palau Headquarters.

In 2021, Arnold Fasteners (Shenyang) Co. LTD installed a vacuum evaporator for the electroplating process, which made it possible to reuse process water and thus reduce the consumption of fresh water. The wastewater is separated into sludge and distillate, which is then fed back into the process instead of fresh water. Since it was put into operation, approx. 65,400 m³ of wastewater have been separated into 64,400 m³ of distillate and approx. 1,000 tons of sludge. The sludge containing heavy metals, suspended matter, and chemical residues is disposed of properly. This technology is currently the most ecological and economical solution for treating electroplating wastewater, laundry wastewater, and lubricating/cooling emulsions from the manufacturing process.

As a screw specialist for timber construction, sustainability and environmental protection are key components for the growth strategy of SWG Schraubenwerk Gaisbach GmbH (Production). The company’s own production floor with offices demonstrates that it is possible to construct industrial buildings out of timber instead of steel and reinforced concrete, thus capturing eleven times more CO₂ than conventional buildings. A total of 1,800 m³ of wood were used for the new building. 400 m³ of this are beech laminated veneer lumber and result in the largest roof structure in the world made of this innovative and high-strength material (trade name BauBuche). Thanks to the ASSY^® wood screws approved specifically for this project as fasteners, the rooftop spans up to an impressive 40 meters in width. Furthermore, by using another 1,400 m³ of softwood materials, the builders were able to support the forestry sector in developing diverse mixed forests. In doing so, SWG hopes to cultivate and help shape a new sustainable building culture.

From product development, use and repair through to reuse and recycling, Würth is committed to preserving valuable materials in the long term. The aim of the Circular Power Tool strategy is to keep valuable raw materials in cycles. This should also reduce the ecological footprint and potential negative social impacts. A particular highlight of the award-winning M-CUBE Power Tools are the world's first Cradle to Cradle^®-certified cordless drill drivers ABS 18 Compact and Subcompact. Following successful pilot projects, Würth is taking its sustainability strategy to a new level with this initiative and demonstrating that corporate responsibility and economic success can go hand in hand in a circular future. The awarding of the German Sustainability Award 2025 to the M-CUBE Power Tools represents an important milestone on this path and a strong statement of the company's commitment as a co-creator of a sustainable economic system.

Würth International is one of three central purchasing companies in the Würth Group. Compliance with social standards in the supply chain is among the most essential pillars of procurement management. Würth International AG's declared aim is to establish and further develop long-term supplier relationships in compliance with sustainable and social standards, for which the German Supply Chain Due Diligence Act and its direct counterpart, the Swiss Responsible Business Initiative, form the legal foundation. Würth International only considers companies that meet specified social standards to be reliable partners. This is monitored by setting up a risk management system, conducting regular risk analyses, and taking appropriate remedial measures such as training, mandatory declarations, and regular assessments to further develop suppliers.

In order to verify whether suppliers meet social standards, Würth Electronics in Shenyang, China, uses self-assessment forms before initiating a business relationship. This has applied to major suppliers of raw materials since 2019 and to suppliers that only supply equipment since 2023. Prospective suppliers first receive two questionnaires: one on environmental safety measures and one to assess their own social responsibility. To be considered as a business partner, they must score a minimum number of points on each questionnaire. They must also sign a supplier code of conduct before the business relationship can begin. Through these measures, Würth Electronics Shenyang wants to deliberately avoid business relationships with risky suppliers from the outset.

Würth Industrie Service GmbH & Co. KG has established an international network of source quality engineers (SQE) who systematically audit and develop the suppliers of critical fastening elements in close collaboration with the entire Würth Group. This international network of the Industry division consists of approximately 30 highly qualified colleagues who are stationed in the main procurement markets for fasteners across the globe. This network is rounded off by additional source quality engineers from other business units. Audits are carried out according to uniform standards and are coordinated centrally by Würth Industrie Service GmbH & Co. KG. In addition to the systematic screening of quality risks, the network also discusses general risks related to environmental hazards, occupational health and safety, and compliance with social standards. The results form the basis for decisions to approve suppliers for the entire Würth Group.
