Statement of the Board of Management on sustainability

Kurk Wilks (CEO) & Emese Weissenbacher (EVP & CFO)

As management, we consider it our special duty to consider the ecological, social and economic consequences of our actions. At a time when the challenges of climate change, social inequalities and rapid technological change present us with new tasks every day, our commitment to sustainability remains firmly integrated into our business strategy.

The year 2023 marks another significant step in our development towards sustainable and future-oriented corporate management. In the area of human rights, the year was marked by the German Supply Chain Due Diligence Act, which is relevant for the MANN+HUMMEL Group. The creation of transparency regarding working conditions in our supply chain and in our own company is part of this legal requirement. To this end, we have established a corresponding risk management system, appointed a human rights officer, added a human rights statement to our Code of Conduct/Social Charta and introduced operational processes. Respect for human rights and fair working conditions has always been part of our business ethics, including an open speak up culture.

This Sustainability Report, prepared in accordance with the recognized guidelines of the Global Reporting Initiative (GRI Standard 2021), provides you with a comprehensive overview of our efforts and achievements in 2023. It highlights not only the progress we have made together with our employees, partners and stakeholders, but also the challenges we have encountered along the way.

Our sustainability strategy is based on three central pillars: protecting our planet, promoting social prosperity and strengthening responsible governance structures. These pillars are anchored in all areas of our company and guide us in every decision we make.

As a technology company, we can continue to provide optimized solutions to separate useful from harmful influences in addition to these three pillars of sustainability.

Last year, we made further progress in reducing our CO2 emissions, further developed our circular economy models and expanded our initiatives to promote occupational safety. As a result, we were able to determine the lowest incidence and severity rate for occupational accidents since records began 10 years ago.

These positive developments are overshadowed by a death during working hours. Our condolences go out to the family of our colleague.

We recognize that there is still much to be done. Sustainability is a continuous process that requires constant learning and adaptation. We are therefore committed to intensifying our efforts, embracing new technologies and innovations, and working with our stakeholders to develop sustainable solutions that create long-term value and support our customers on their journey towards greater sustainability.

In conclusion, we would like to express our sincere thanks to everyone who has contributed to this progress. Our success is the result of hard work, collaboration and a shared belief in a sustainable future.

We look forward to continuing on this path and shaping a world together in which economic success and sustainable development go hand in hand.

Our guiding principle for sustainability remains:

Perform to Transform!

For the seventh time, MANN+HUMMEL presents a complete overview of its corporate responsibility in the form of a Corporate Responsibility Report. This report has been prepared in accordance with the GRI Standards: Core option. We highlight the focus of our corporate social responsibility using the four areas of 'Our value added', 'Our environment', Our employees', and 'Our governance'.

Sustainability Strategy - our understanding

We have a clear understanding of our Corporate Social Responsibility.
  • As leader in Filtration, we enable our customers to be more sustainable.
  • As a company, we are active contributor and we take responsibility for our business, our employees, our value chain and our planet.
  • We have the intention to promote company actions in harmony to our business interest as well as regulations.

In addition to behavioral changes in the use of resources and a fundamental rethinking of product design, production, operation, and recycling, we at MANN+HUMMEL are using technology to make our world more sustainable and cleaner.

As a world-leading filtration company, we focus on filtration with the aim of separating the useful from the harmful. We develop solutions that enable cleaner mobility, air and water and deliver key technologies that pave the way to a cleaner planet.

Our employees make the difference

Santhosh AV

Cleaner air for cities

Form follows function. Or vice versa? We are no fans of dirty city air and urban uniform gray. VERTO AirCubes filter the air where it is the dirtiest in the world's biggest cities.

Amanda Mpoyi

Cultures shape markets.

Knowing markets means understanding cultures. Understanding cultures is MANN+HUMMEL’s DNA. It is not what is technically feasible that is decisive, but desire and need.

Matt Zerilli

Experience meets startup.

Startups are shaking up the market for electromobility. They provide strong impetus for innovative solutions. We add more than eight decades of filtration know-how.

Tiago de Oliveira

Problem solving means finding the root cause

Root canal treatments are painful. But necessary and effective. If you only fight the symptoms, you will fail in the long run. That's why we analyze problems in depth and eliminate the cause. Then it works. Permanently.

Daniela Lißon

Making the world a better place. With the best.

MANN+HUMMEL is active worldwide. This also applies to our recruiters. We are looking for bright minds to continuously improve our outstanding team.

Raja Karthik

Clean drinking water for India

Doing business successfully on a sustainable basis also means taking responsibility. Not only at the company headquarters, but worldwide. In India, MANN+HUMMEL supports the surrounding villages in the supply of clean drinking water.

Marcus Muncan

Money must be green.

Our logo is green and so is our financing: With our promissory bill, the interest rate is linked to our sustainability rating. The more sustainable we are, the lower our interest rate. A turbo for our transformation.

Matthew Nunn

Digitalization is everything.

Our core product may be analog. We are not. Digitalization helps us making our logistics, finance, HR and product development more efficient and sustainable.

Rikki He

Bi-cultural resilience

In an increasingly fast-changing world, old certainties are being shaken. Supply chains are turning upside down. The distribution of goods between international markets follows new laws. Intercultural competence becomes key to success.

Dennis Baiao

Smart data usage

Intensive data analysis means added value for customers. That's what we're working on. And the algorithms. 24/7.

Joomi Kim

Unique position? Good idea!

Filters filter all sorts of things. Why not filter the odors in South Korean barbecue restaurants? Now barbecue becomes a pure taste experience - without annoying odors.

Nick Wang

The somewhat different shared apartment

If you can't get outside, you stay in. 200 employees move into the factory, defying the rigorous curfews in Shanghai. This is true team spirit.

Veeresh Chandrashekhar Patil

Gaining an overview; saving time

Who wants to see well, uses glasses. Who wants to see more, use augmented reality glasses. We look at things very closely. Analog and digital. And sometimes from several thousand kilometers away. 

Dominik Schreier & Maximilian Werner

Medical drugs: a universal remedy?

Modern medications are meant to do good, but they don't cure everything. Sometimes they make things worse—for example, in our wastewater. We ensure that everything that should not be in our water is safely filtered out.

Sabrina Herrmann

Chemistry must be right

It takes two to tango. And chemistry plays a big role. This is true not only for successful cooperation with customers, but also when it comes to binding odors permanently. We take care of that. In the kitchen. In the bathroom. And wherever else there is bad air.

Cleopatra Moscoso

Talking to each other

Some solutions need to be explained. The best way is to talk directly to the customer. We walk the talk. Even if it takes hours and days.

ESG Commitment and Ratings

UN Global Compact

MANN+HUMMEL is participant and supporter since 2021.

The UN Global Compact is the world's largest and most important initiative for sustainable and responsible corporate governance. The UN Global Compact Network Germany (UN GCD) with 1,100 participants from business, civil society and politics supports companies in strategically anchoring sustainability on the basis of 10 universal principles and contributing to the implementation of the Sustainable Development Goals.

CDP Ratings

The CDP (Carbon Disclosure Project) is a non-profit organization that operates an international system for the disclosure of environmental data. Companies and public institutions report on their environmental impact, such as greenhouse gas emissions and water consumption.

The CDP rating evaluates companies on the basis of several criteria contained in the CDP questionnaires on climate change and water security. 

A CDP score provides a snapshot of a company’s disclosure and environmental performance. Bold environmental action must begin with an accurate, transparent assessment of environmental impact and progress, which CDP scoring makes possible.

Actual Rating status

CDP Climate Change: rating grade 2023/2024 “B” (2022: “B”) 

CDP Water Security: rating grade 2023/2024 “B”

EcoVadis

EcoVadis is a global platform for sustainability ratings in the field of corporate responsibility. The EcoVadis ratings assess, among other things, the impact of companies on the environment, labor and human rights, ethics and sustainable procurement.

Actual Rating status

For the fourth time since 2021, MANN+HUMMEL is among the top 5% of all 130,000 companies evaluated and was once again awarded a Gold Medal.

EcoVadis Rating 2024/2025: Gold / 75 points
