In the steel industry, saying “we are green” is easy. Demonstrating a steel sustainability rating with data validated by third-party bodies is much harder. Our partner Swiss Steel Group has achieved a historic milestone, earning the highest possible score, “A”, in the CDP Climate Change Rating. This result did not come by chance, but is the outcome of a strategic path of continuous improvement: from a “C” in 2022, to a “B” in 2023, and finally to the excellence of an “A” in 2024.

Why is this rating so important? Because it certifies that our climate targets are science-based. A key factor in this assessment was validation by the SBTi (Science Based Targets Initiative), the international partnership that verifies whether corporate strategies are aligned with the goal of limiting global warming to 1.5°C above pre-industrial levels by 2050. In 2024, Swiss Steel Group became the first steel producer in the world to have its sectoral decarbonisation targets validated by the SBTi.

Consistency is everything. The CDP rating does not stand alone, but is confirmed by other high-profile independent assessments:

• EcoVadis Gold (2025): We received the Gold Medal, placing us among the top 5% of companies evaluated worldwide.
• German Sustainability Award (2024): Winner in the “Metallurgical Industry” category.

All these awards are based on externally validated data and indicators, confirming that the transformation toward sustainable management is real and measurable.

You might ask: “What difference does it make to my workshop if the steel mill has an A rating or a gold medal?” The answer is: a lot. In an increasingly interconnected market, the steel sustainability rating of your supplier directly influences your own company rating. Here is how Bonomi Acciai turns these recognitions into added value for you:

1. Supplier Evaluation (Automotive and Mechanical Engineering)
The CDP rating is becoming critically important in B2B business. Major players in the automotive and mechanical engineering industries increasingly integrate CDP data into their “Vendor Lists”. Buying from Bonomi Acciai (Swiss Steel partner) means having a supplier already qualified with top scores, simplifying your audits and accreditations.

2. Access to Credit and Investors
Banks are also looking at this data. Financial institutions use the CDP database to assess climate and ESG risks in financing decisions. Demonstrating an “A-rated” supply chain improves your risk profile and can facilitate access to credit lines or green investments.

3. Ready for the CSRD Directive
Sustainable bureaucracy is coming. Voluntary participation in the CDP program serves as structured preparation for the requirements of the EU reporting directive (CSRD). The standardized information we provide allows you to present your sustainability report content in a comparable, verifiable, and consistent way. In practice: we give you data ready to be included in your reporting.

4. Reputation Protected
Using steel certified EcoVadis Gold and SBTi validated is a powerful marketing tool. You can tell your end customers that your products are made with materials from one of the most sustainable supply chains in the world, protecting your brand from the risk of greenwashing.

An “A” steel sustainability rating is not just a letter on a certificate. It is the guarantee that Bonomi Acciai and Swiss Steel Group are not merely reacting to climate change, but actively leading it. Choosing us as a partner means bringing into your company a strategic asset worth its weight in gold: credibility.
