Croonwolter&dros

From sustainability report to impact platform

Croonwolter&dros brings technology to life. For more than 150 years, the organisation has been developing smart solutions for buildings, infrastructure, industry and digital security.

‍

This year, Croonwolter&dros set out to create its first sustainability report, covering 2025. But the ambition went beyond CSRD reporting. Sustainability and innovation needed to become a strategic story. One that provides direction, strengthens pride within the organisation and clearly communicates what Croonwolter&dros stands for to the outside world.

The Challenge

Making technology meaningful

Croonwolter&dros makes an impact every day. With technology that makes tunnels smarter, buildings more sustainable, maintenance more predictable and digital security stronger. From circularity to the energy transition, there were plenty of examples. Now it was time to make them visible and easy to understand.

Croonwolter&dros wanted the sustainability report to become more than just a publication. It needed to tell a story that provides direction, creates recognition and engages clients, partners, stakeholders and employees. That is why the scope was broader: develop the messaging, storytelling, copy, design and activation, and bring it to life across the website, video, social content and commercial materials.

The Approach

Define the direction first, then bring it to life

During strategic deep dives, we clearly defined what Croonwolter&dros wanted to communicate, who the story was for and what it needed to achieve. The key insight: Croonwolter&dros was already showing what it does, but not yet enough of why it matters.

From this foundation, we developed the strategic framework, naming, overarching concept, tone of voice, storytelling structure and a distinctive visual style. This led to Stories of Progress: an impact platform that shows what technology can achieve for people, organisations and the world around us. ESG was not the format of the story, but the foundation beneath it.

We then translated the story into an online impact platform, impact report, social content, templates, cases, interviews and commercial materials. This turned the report from an end point into the starting point of a much bigger story.

The effect*

A platform that makes impact visible

With Stories of Progress, Croonwolter&dros can communicate its positive impact on society more clearly. The stories were already there within the organisation. Through interviews and case studies, we brought them to the surface, connecting people, projects and results and turning them into content that can be used across different channels and moments.

The result is a strong communications foundation that builds pride internally and positions Croonwolter&dros externally as an innovation partner in sustainability, safety and the energy transition. And the best part: the story does not end with publication. Croonwolter&dros can continue to expand the platform with new projects, insights and results, allowing Stories of Progress to grow alongside the organisation.

The approach also caught the attention of partners across the value chain. A great indication that the story creates value beyond the organisation itself.
