“Sustainability and responsibility are the guiding principles of our company’s actions.”
– Erich Sixt
Sharing mobility instead of owning it.
That’s the guiding idea behind SIXT. Beyond that, we are actively working to electrify our fleet in line with customer demand, to measure and reduce our own emissions, and to report transparently on our progress.
Our Sustainability Strategy
Another aspect: the average age of vehicles in the SIXT fleet is significantly under one year. This means we help ensure that the vehicles on the road are as new as possible - and therefore technologically state-of-the-art, particularly with regard to their emissions performance.
Since 2023, we have offset any remaining emissions annually through compensation projects. The emissions from our rental fleet are not part of this offsetting. Between 2023 and 2025, certificates covering a total of 44,013 tonnes of CO₂ were purchased and retired. These projects originate from recognized climate protection standards (Gold Standard, Verra/VCS, and Climate Action Reserve).
ISO Certification: Our environmental and quality management system is certified according to ISO 14001:2015 and ISO 9001:2015 (issued by TÜV SÜD, valid until 2027). The scope covers the car rental business at several hundred locations in Germany.
CDP Reporting & CSRD: SIXT publishes its Corporate Carbon Footprint annually through the CDP (Carbon Disclosure Project). This data is publicly available. Starting with fiscal year 2025, we will additionally report under CSRD.
Scope 3 Emissions: The majority of our climate-relevant emissions arise upstream in the supply chain and through customer use of our vehicles (Scope 3). Electrifying our fleet is therefore the most effective lever available: every electric vehicle in our fleet directly reduces these emissions.
ESG Governance: ESG targets are embedded in the Management Board's compensation, and one Board member holds formal responsibility for this area.
Culture & New Work
SIXT stands for a culture with strong corporate values. We rely on first-class leadership and innovative ways of working. And on our unique “Team Orange.”

We are not a car rental business serving people. We are a people business renting cars.”
In our Code of Conduct, you will find the basic principles and standards of behaviour of our company, with regard to ecology, social responsibility and governance, for example.
In addition, we give all of our employees and external stakeholders the opportunity to use our integrity tool to report misconduct or raise complaints about deficiencies related to human rights, environmental damage or ethical misbehavior within our supply chain.
Please note that more general comments regarding SIXT´s service or customer experiences should not be addressed to this platform but rather be sent to SIXT’s customer service.
Our policy statement represents an important step along this route. We also realise that doing business sustainably is a shared task.
Supplier Code of Conduct
We strive to create responsible and sustainable value across our entire business spectrum and value chain. Our company’s performance is not based solely on successfully managing the business but also requires both, legal compliance and ethically impeccable behavior. This is essential in order to justify the confidence that customers and suppliers, shareholders and business partners as well as employees place in us. We expect our suppliers to follow the same principles. They must internalize our principles, which are manifested in our Code of Conduct, and promote them just as actively as we do. Our Supplier Code of Conduct reflects SIXT’s fundamental principles and sets minimum standards for business relationships with Sixt SE or any of its affiliated Group companies.
