MANN+HUMMEL: Sustainability report 2024
Statement of the Board of Management on sustainability
Kurk Wilks (CEO) & Emese Weissenbacher (EVP & CFO)
Filtration is much more than a technical solution; it is a key technology for a sustainable future. Whether it’s cleaner air, cleaner water, cleaner mobility, cleaner industry, or resource-efficient production, our solutions actively contribute to achieving the United Nations Sustainable Development Goals (SDGs).
Our responsibility goes beyond our products. In a dynamic world, adaptability is essential—for our technologies, our processes, and our organization. Through digitalization, sustainable action, and agility, MANN+HUMMEL continuously puts its customers at the center of progress.
As a signatory to the United Nations Global Compact (UNGC), we are fully committed to its 10 principles in the areas of human rights, labor standards, environmental protection, and anti-corruption. Sustainability is an integral part of our strategy.
In 2024, we reduced our carbon footprint by 9% — despite a slight decline in sales. A recycling rate of 97% in the Transportation division and the lowest accident downtime since we began recording these numbers are further proof of the effectiveness of our measures.
With our revised management policy, we are setting new standards, including commitments to climate neutrality, product safety, and human rights. The German Supply Chain Act (LkSG) and transparent supply chains are central components of our environmental, social, and governance (ESG) approach.
We are also preparing intensively for the Corporate Sustainability Reporting Directive (CSRD) and other regulatory requirements. Together with the increasing number of new ESG regulations worldwide, this marks a change towards more transparency and comparability.
This requires not only professional expertise but also entrepreneurial agility to both adapt processes and structures flexibly and communicate our sustainability performance in a credible, measurable way.
For us, sustainability is a continuous learning and development process. With every solution and every filter, we contribute to a better future.
We would like to thank all our employees, partners, and friends who have shaped this path with their commitment and conviction.

MANN+HUMMEL is also providing information on its strategies and progress in the area of corporate responsibility for the 2024 fiscal year in the form of a sustainability report. This report was prepared in accordance with the GRI standards for the 2024 fiscal year and also serves as the progress report in accordance with the UN Global Compact (CoP). We highlight the focus areas of our corporate responsibility in four areas: “Our value creation,” “Our environment,” “Our employees,” and “Our governance.”
Performance and responsibility for a sustainable future
We ensure that sustainability is part of every product by combining performance with purpose to create lasting value for our customers and our planet.
For example, at Heathrow Airport, we advanced sustainability efforts and ensured optimal air quality, protecting 75,000 employees and 20 million passengers annually from harmful particulate matter, viruses, bacteria, and other airborne pollutants.
- For example, at a university in Scotland, we ensured optimal protection against air pollutants in approximately 300 buildings, resulting in annual savings of around £179,000 and 170 tons CO₂, reducing energy consumption by approximately 813,000 kWh per year.
We develop innovative solutions for the filtration of particulate matter and nitrogen dioxide to improve outdoor air quality.
Responsibility in production
We transform the way we produce to make our processes more responsible and resource-efficient – paving the way for a more sustainable future.

Our technologies help to improve air and water quality, thereby contributing to the realization of the Sustainable Development Goals, particularly SDG 3 (Good Health) and SDG 6 (Clean Water).
A focus on improving machine safety and adopting a safety-first mindset has led to a 29% drop in accident rates since 2020, resulting in our lowest ever recorded accident rate.
