Environmental and social measures at Maritim Hotels
For more than five decades, hospitality, warmth and quality have shaped Maritim's identity. We are proud to carry these values forward into the future. We are convinced that lasting success can only be achieved through responsible action.
Environment
We want to offer our guests the highest level of comfort while using resources in hotel operations in a targeted manner. To achieve this, we record energy and water consumption, implement measures to reduce it, avoid and separate waste, and take environmental and social criteria into account in procurement decisions.
Social
People are at the heart of everything we do. We welcome all guests and create a respectful environment for our employees. We promote diversity, fair working conditions and lifelong learning – and we are committed to upholding human rights throughout our supply chain. In addition, we engage locally through social projects, partnerships and the promotion of regional economic cycles. In this way, we combine hospitality with social responsibility.

“ProUmwelt” Policy
In 2010, Maritim Hotelgesellschaft developed the ProUmwelt Policy, which is based on the three-pillar model of ecology, economy and social responsibility.
For its implementation, Maritim groups its measures into six areas of action: energy, waste, water, procurement, mobility and employees. Projects in these areas are characterised by optimisations in day-to-day operations, innovations in new buildings and renovations, and careful documentation of the measures implemented.
Energy
Energy consumption at our locations is recorded regularly and evaluated as part of a certified energy management system in accordance with ISO 50001. Depending on the location, the hotels are heated using natural gas or district heating; heating oil is not used in operations managed by Maritim. Some locations have their own combined heat and power units, which generate electricity for hotel operations in addition to heat.
With an investment of more than one million euros, all hotels have increasingly been converted to LED technology. According to manufacturers' specifications, LED lamps consume up to 80 per cent less electricity than standard incandescent bulbs. In addition, timers are used in all hotels to control lighting according to demand – particularly in public areas, from underground car parks to corridors. For air-conditioning and ventilation systems, we use recirculating air systems at almost all locations and have also retrofitted heat recovery systems at several locations. Further modernisation measures are being carried out successively depending on the location.
Procurement and delivery logistics
Maritim consolidates procurement for the individual locations and coordinates delivery dates centrally. This makes it possible to reduce the number of deliveries to the respective hotels.
For seasonal fruit, vegetables, salads and herbs, the hotels have access to a supplier database containing producers from the respective hotel regions.
When it comes to furnishings and equipment, Maritim deliberately chooses high-quality materials. Existing furnishings are repaired or refurbished wherever possible, even if this is more time-consuming in individual cases than purchasing new items. This focus on quality is established as a principle in our mission statement.
Employees and responsibility
The company's employees regularly receive training on environmental protection issues from the hotels' technical specialists. As a provider of large conference capacities in the hotel industry, Maritim places particular emphasis on the events sector. Sustainability advisers have been trained for all 24 German Maritim Hotels. The basis for this is the “Fit for Green Meetings” training programme offered by the German Convention Bureau e.V. in cooperation with the German Federal Environmental Foundation (DBU).
As a premium partner of the German Convention Bureau (GCB), Maritim has also signed the sustainability code for the German events industry. The declaration of support is based on recognition of ten guidelines and a commitment to regularly document progress www.fairpflichtet.de.
GreenSign certification
Since 2026, 24 Maritim Hotels in Germany have been certified according to GreenSign and therefore meet a sustainability standard developed specifically for the hotel industry.
GreenSign certification includes an assessment based on defined criteria and an on-site audit, covering areas including environmental management, energy and water consumption, waste prevention, social responsibility and regionality. The independent assessment supports the hotels in implementing sustainability measures and provides impetus for continuous further development.
