Statement of the Board of Management on sustainability

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

At MANN+HUMMEL our sustainability transformation is based on clear values and our vision of Leadership in Filtration. We want to support our customers on their way to more sustainability and drive our own transformation in parallel.

The pursuit of sustainability is not a luxury, but a compelling necessity in order to dovetail entrepreneurial activity with social and ecological progress. 

This insight is not new at MANN+HUMMEL, but has been evident in our corporate philosophy since the company's beginnings: separating the harmful from the useful. We not only support our customers on their way to more sustainable products and services, but also work in parallel with all our strength on the social and ecological optimization of our own processes and solutions.

In the past reporting year 2022, we sharpened our focus in all dimensions of our sustainability strategy (ecology, economy, social affairs and technology); on the basis of an updated double materiality analysis, we focused on ten topics.

We are implementing our Carbon Zero Strategy with groupwide packages of measures. The successes are evident in the reporting year: Despite a significant increase in production volumes, we reduced both the specific use of resources per product and CO2 emissions by 19 percent compared with the previous year. In return, we reduced our own energy consumption by 5 percent compared with the previous year. On balance, we obtained our electricity entirely from renewable sources. In this way, we are shaping our transformation process toward CO2-neutral production and, in the long term, a CO2-neutral value chain in 2050. We are thus on the right track, as confirmed by the external CDP climate rating, in which we improved to a B rating. 

As a member of the UN Global Compact, we are committed to the ten principles of this United Nations initiative in the areas of human rights, labor standards, the environment, and anti-corruption. 

For MANN+HUMMEL, human rights are indispensable pillars of business interaction. It is therefore no surprise that there were no confirmed cases of human rights violations at MANN+HUMMEL in the year under review.

In preparation for the introduction of the German Supply Chain Due Diligence Act (Lieferkettensorgfaltspflichtengesetz) on January 1, 2023, we have updated and once again expanded our monitoring and control mechanisms in the context of human rights in our group of companies and our supply chain.  

Independent sustainability ratings confirm that we have taken the right course. MANN+HUMMEL is among the top five percent of companies evaluated in the ecoVadis® rating and was again awarded the gold medal in the reporting year. 

We are pursuing this path with conviction: Employees and all management levels are aware of the positive impact of forward-looking planning and early anticipation of opportunities and threats. We are all committed to the ambitious goals we have set ourselves in our strategy.

This is our path to a sustainable future.

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 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

CDP is the gold standard for corporate environmental reporting and is fully aligned with the TCFD recommendations.

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 2022 “B” (2021: “C”) 

CDP Water Security: rating grade 2022 “C”


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.
