Our areas of action in governance
Ariane Bischoff: Solingen can only achieve its sustainability and climate goals when everyone participates – companies, associations, institutions, and households.
Local businesses play a key role. They account for around 38 percent of Solingen’s energy use and 40 percent of its greenhouse gas emissions. Their commitment is crucial for the city’s economic strength and for securing jobs and training.
Over the past decades, companies have helped reduce the city’s total energy and resource consumption by about 37 percent since 1990, as shown in Solingen’s 2023 greenhouse gas balance. This progress also brings direct economic benefits.
Solingen’s climate neutrality roadmap, adopted by the council in 2024, shows that switching fully to renewable energy – alongside saving energy – offers great potential. By moving electricity and heating to renewables, as planned in Solingen, nearly half (47 percent) of citywide greenhouse gas emissions can be reduced.
ZWILLING’s goal to reduce absolute CO₂ emissions at production and logistics sites by 42 percent by 2030, compared to 2021, and to use 100 percent green electricity in Solingen, clearly contributes to the city’s climate targets. Lowering the CO₂ footprint of products is challenging, especially with energy-intensive, fossil-based steel processes. With a new knife made from emissions-reduced steel that cuts the CO₂ footprint by 50 percent compared to conventional knife steel, ZWILLING shows that solutions are possible. These solutions need to reach more people, and for that, consumers need to recognise and choose these valuable products.
A key part of Solingen’s climate neutrality plan is to minimise raw material use and waste by encouraging everyone to create and use durable, circular materials and products. Advancing innovative solutions means rethinking production, supply chains, and business models. In this spirit, ZWILLING’s project to return steel offcuts from its production back into the steelmaking process is a scalable, circular approach.
Ariane Bischoff: Many people are open to sustainable, resource-saving habits when they see the benefits and can easily put them into practice. However, for many, how food and products are made has become distant. Often, people do not see the effort behind healthy, durable, high-value products and may choose seemingly cheaper, less sustainable items – even if they could afford sustainable ones. Companies, retailers, and education providers need to make the advantages clear and tangible.
ZWILLING shows how long its products last and offers repair and resharpening services, reaching conscious consumers. It is important to apply sustainability principles visibly and consistently – for example, by designing products with FSC®-certified, preferably regional wood for handles, or using minimal, recycled packaging, as ZWILLING already does for certain product lines. The company’s vacuum system, which keeps food fresh longer and helps reduce food waste, is another example of how innovative products can make sustainable living easier.
In Solingen, the “Gläserne Werkstatt” (Transparent Workshop) is a place for quality and sustainability, aiming to become a marketplace for sustainable products from Solingen and the region. As a city lab and creative space, it brings resource-saving habits closer to people of all ages with cooking workshops, do-it-yourself sessions, and repair cafés.
Solingen’s broad-based climate and sustainability education – now established in many nurseries, primary schools, secondary schools, youth centres, and even sports clubs – helps children, young people, and families embrace sustainable lifestyles.
Ariane Bischoff: Decent living and working conditions, fair pay, and standards for health, social care, and education are essential for us – but worldwide, they remain a major challenge and are crucial for achieving universal human rights and sustainability goals. Solingen is working to make its own procurement socially and environmentally responsible. International companies need to implement the Supply Chain Due Diligence Act step by step, using risk analysis, prevention, and controls along the value chain.
ZWILLING applies a code of conduct for suppliers with binding ecological and social standards, conducts training and audits worldwide, and provides disadvantaged children and young people with access to education and health care at its international sites. This shows responsibility and social commitment.
Implementing human rights and environmental standards throughout the entire value chain, especially in complex supply chains, is a long-term task, especially as global changes continue. ZWILLING’s use of BSCI audits to identify supply chain risks demonstrates its commitment to solutions.
Those responsible at company sites need to identify and resolve any issues in the supply chain. At the same time, it is important to involve consumers and show how social and environmental standards are put into practice in product lines. Since 2018, Solingen – the “City of Blades” – has been a certified “Fairtrade Town”, joining over 900 communities worldwide that promote sustainable procurement and fair trade through public activities. Solingen works with partners from retail, churches, civil society, and education. Practical examples from Solingen companies are always welcome.
