NetZeroDéifferdeng 2030

Differdange stands at the forefront of an extraordinary movement. With over 70% of global CO2 emissions originating from urban areas, and cities being the living space of most EU citizens, the role of cities like ours in tackling climate change is undeniable.

Differdange is more than just a city; it’s a hub of economic activity, knowledge, and innovation. Historically, cities have been the birthplace of significant changes and advancements. In this tradition, Differdange is ready to lead the charge in reducing greenhouse gas emissions, fostering equitable decarbonisation, and enhancing the well-being of our community.

EU policies in action: Differdange’s path to climate neutrality

The European Union, recognizing the crucial role of cities in climate action, has set ambitious targets through initiatives like the Horizon 2020 and Horizon Europe research programs, as well as the European Green Deal. These initiatives aim for a 55% reduction in emissions by 2030 and achieving climate neutrality by 2050.

Differdange’s mission: becoming a climate-neutral and smart city

In alignment with the EU’s Horizon Europe program, Differdange joins the ambitious ‘100 Climate-Neutral and Smart Cities by 2030’ mission. This initiative positions Differdange as a leader and innovator, with the goal of not only achieving climate neutrality by 2030 but also serving as a model for other European cities to emulate by 2050.

Differdange is committed to this path, leveraging innovation and smart solutions to build a vibrant, sustainable future for all its residents.

Join us in shaping a sustainable Differdange

This mission is more than just a policy; it’s an opportunity to reimagine our way of life. It’s about creating new jobs, evolving business models, and fostering a community that values sustainability, cooperation, and innovation. Join us in this transformative journey as Differdange paves the way towards a greener, smarter, and more inclusive future.

The City of Differdange and the non-profit organization CELL invite you to a co-creation workshop on Sunday, November 29, 2026. Come share your ideas to help bring to life a community garden that reflects its residents—no prior knowledge is required.

A community garden will soon be created in the heart of Differdange, on the lot located at 30 Grand-rue. But what will it look like? Who will take care of it? What goals will it pursue? The City would like to answer these questions together with you.

On November 29, 2026, the City of Differdange and the CELL ASBL (Centre for Ecological Learning Luxembourg) are organizing a participatory workshop open to everyone. After a brief presentation by the two partners, participants will work in small groups on various aspects of the future garden:

  • The layout of the plot;
  • Governance and day-to-day organization;
  • Objectives and partnerships;
  • The circular economy.

Whether you have a green thumb or have never planted a seed, your perspective matters. The workshop will be held in French, with translation into Luxembourgish and English.

To ensure everyone can participate comfortably, childcare with arts-and-crafts and upcycling activities will be provided throughout the workshop. The morning will conclude with a friendly lunch provided by the municipality.

How should we prepare Differdange for tomorrow’s climate challenges?

This is what we would like to explore together on Sunday, 11 October, from 2.30 to 4 p.m. at the 1535° Creative Hub, as part of the Creative Day.

As part of Net Zero Déifferdeng 2030, the city is inviting residents to a participatory workshop focusing on climate adaptation. Heat waves, heavy rainfall and flooding, periods of drought and extreme weather events: our city will increasingly need to prepare for the effects of a changing climate.

How can we make our neighbourhoods, public spaces and buildings more resilient? Which places or groups of people are particularly vulnerable? Which measures should be prioritized? And how can the city, residents, property owners, businesses and other stakeholders work together?

During the workshop, participants will be invited to share their experiences and knowledge of Differdange, identify risks and particularly vulnerable locations, and explore possible solutions to better protect the city and its residents. The contributions collected will feed into the ongoing work around Differdange’s Climate City Contract.

The workshop takes place during the Creative Day. You will also be able to visit our participatory exhibition on climate adaptation and contribute your ideas outside the workshop itself.

What if your neighborhood generated its own energy? That’s exactly what we’ll be exploring together on June 13 at 9 a.m. at the 1535° Creative Hub.

As part of the Net Zero Déifferdeng 2030 initiative, the City invites its residents to a participatory morning event focused on energy communities—a practical model that enables neighbors, families, businesses, and institutions to produce and share renewable energy at the local level. Less dependence, lower bills, stronger connections.

The morning will be divided into two parts. First, an informational session: where does Differdange stand in its energy transition? What solar projects are underway or planned? How does an energy community actually work? City experts and external speakers will be on hand to answer your questions.

Then, it’s time for action. Using maps and simple tools, you’ll work on the idea of an energy community in your own neighborhood: identify your potential neighbors, understand the 300-meter radius principle, and brainstorm together the first steps of a real project.

Children are welcome. Drinks and snacks will be provided. And after the workshop, a group lunch will give you a chance to continue the discussion in a friendly atmosphere.

Your neighborhood can become a place for concrete action.
Come discuss it—and maybe leave with a project.

The Municipal Council of Differdange signs the Climate City Contract (CCC) and will be the only city in Luxembourg to join the European Union’s 100 Net-Zero Cities.

The city of Differdange is committed to achieving the EU mission of “100 smart and climate-neutral cities by 2030” to combat climate change, promote a sustainable future and increase the attractiveness of the region with regard to circular economy. The city will engage in technical and scientific exchange with other cities by sharing knowledge and developing innovative solutions. The NetZeroCities label gives Differdange access to globally recognized experts in the field as well as funding opportunities. Differdange aims to achieve a net-zero target by 2030 by increasing the energy efficiency of buildings, supporting renewable energy, promoting sustainable mobility and reducing waste. The city has demonstrated its commitment to climate action through initiatives such as the Climate Pact, Climaborough, Climate Alliance and FUSILLI, to name a few.

The Climate City Contract (CCC), signed by the Municipal Council on 29 March 2023, outlines the city’s commitments to climate action and builds a partnership with citizens to work towards a carbon-neutral and climate-resilient future.

The city has identified five systemic, strategic priorities necessary to achieve its goal, including increasing the efficiency of stationary energy supply through renovations, self-sufficiency in energy generation, reducing individual mileage, waste reduction and offsetting the tons of CO2 generated by the municipality largely within the city limits.

The city recognizes the need for a just transition and the project implementation process is based on principles such as co-creation, innovation and multi-stakeholder and citizen engagement. This approach ensures that the city’s efforts towards carbon neutrality are systemic, demand-driven and take into account the needs and perspectives of all stakeholders.

Policy makers are aware that it is much cheaper to invest in solutions now than to wait and have to pay for what has been missed. The responsibility to be the last generation to make the right decisions lies with them. Although all members of society are equal when it comes to climate change, the responsibility of current decision-makers towards future generations is enormous.
