Wilhelmshaven in the Climate Change: How the City is Investing in Climate Protection

In April 2026, the city of Wilhelmshaven adopted a series of decisive measures to combat climate change and adapt to its consequences. With the goal of becoming a climate-neutral municipal administration by 2040, Wilhelmshaven has not only sent a strong signal but also defined concrete action steps. The focus is on decarbonization, the production of renewable energy, and the strengthening of climate resilience – especially in the Kurpark, a central green space in the city.

Climate Neutrality of the Municipal Administration: Between Goal and Implementation

The municipal administration of Wilhelmshaven has committed to becoming climate-neutral by 2040. This goal is not only a political statement but also a legal obligation under the Lower Saxony Climate Protection Act (NKlimaG). In 2023, the emissions of the city administration amounted to 17,500 tonnes of CO₂ equivalents, with 96% attributed to the building sector.

To achieve this goal, 31 concrete measures have been defined across five action areas. These include:

• Decarbonization of heating supply through the modernization of heating systems and the use of heat pumps.
• Energy management in municipal buildings to reduce energy consumption.
• Electrification of the municipal vehicle fleet, with the aim of procuring 38.5% of vehicles emission-free by 2030.
• Expansion of renewable energy, particularly photovoltaics on municipal rooftops.
• Sustainable procurement, including the use of recycled paper with environmental labels.

A central success factor is the establishment of a Climate Protection Management (KSM), which will be responsible for coordination and monitoring starting in 2026. The city plans to publish annual reports on the implementation of climate protection measures to ensure transparency and progress tracking.

PV Expansion: Solar Energy for Wilhelmshaven

Another focal point of the climate protection strategy is the photovoltaics expansion strategy on municipal rooftops. The goal is to equip all priority 1 properties with photovoltaic systems by 2030 and all technically and economically suitable buildings by 2040.

The city has already identified 29 roof areas with a potential performance of 2,023 kWp. Funding will be provided from own resources and funding programs. The administration is tasked with assessing the technical and structural prerequisites for the PV systems and preparing projects.

This measure is not only a contribution to the reduction of greenhouse gases but also a step toward energy independence and a model function in the field of renewable energies.

Emission-Free Mobility: From Combustion Engines to Electric Vehicles

The city has decided to procure only emission-free vehicles from now on. This is not only a consistent implementation of the Clean Vehicle Procurement Act (SaubFahrzeugBeschG) but also a model for other municipalities.

The measure aims for a minimum quota of 38.5% clean passenger cars. Exceptions are only permissible if availability is lacking or if it is not economically feasible, and these must be documented.

In addition, the city plans the expansion of charging infrastructure, which plays a central role in the climate strategy. The goal is to establish a comprehensive charging infrastructure for electric vehicles by 2030.

Kurpark Wilhelmshaven: Climate Resilience in the Green

The Kurpark is not only a cultural and natural treasure of Wilhelmshaven but also a central component of the city's climate and nature protection strategy. With the development of a Kurpark concept, the city has placed a focus on adapting to climatic changes.

The aim is to strengthen the Kurpark as a climate-ecological comfort zone while simultaneously promoting biodiversity. This includes measures such as the renovation of ditches and culverts for retention and water retention, as well as the promotion of species diversity through, for example, sinus mowing and double-cut mowing.

In the Kurpark, 1,052 trees (60 species) and 167 herbaceous plant species were recorded, including 7 Red List species. However, the vitality of the tree population is affected by climate change – particularly in hornbeams and ash trees.

The city has therefore also adopted measures for tree care and replanting to ensure the long-term preservation of the tree population.

Winter Service Optimization: Safety in Winter

Another topic discussed in the meetings was the optimization of winter service. With an emergency and deployment plan for extreme weather conditions, the city aims to increase road safety and relieve staff.

Responsibilities for bus stops and school routes should be more strongly assumed by the city. A needs plan for extreme situations will assess personnel and technical resources to better prepare the city for prolonged frost, freezing rain or snowfall.

Outlook: What’s Next?

The measures adopted by Wilhelmshaven in April 2026 mark an important milestone on the path to climate neutrality. The city has not only chosen a long-term strategy but also concrete steps that must be implemented.

The challenges are considerable – particularly financial. Annual investments will be in the double-digit million range, and the acquisition of funding is a central factor for success. However, with the establishment of the Climate Protection Management, the development of measures concepts, and the involvement of various departments, Wilhelmshaven has good prerequisites for achieving its goals.

Thus, the city of Wilhelmshaven stands not only for active climate protection but also for a sustainable future – for its citizens, for nature, and for the generations to come.
