Leuven Climate City Contract

Leuven's selection for the EU mission ‘100 climate-neutral and smart cities by 2030’ accelerates our work towards a climate-neutral future for our city. The Leuven Climate  City Contract, a collaboration between the city of Leuven, Leuven 2030 and more than 30 key actors, is our plan to achieve this. Never before have we brought together so many perspectives and concrete commitments.

The Leuven Climate City Contract contains dozens of breakthrough projects to limit our CO2 emissions and remove barriers that stand in the way of rapid emission reductions. If we manage to scale up these projects, a CO2 reduction of 80% becomes possible. Over 25 key actors also formally commit to 10 guiding principles that put CO2 reduction at the heart of all their future initiatives. In addition, the Climate City Contract includes a financial plan that identifies investment needs and financial levers for the projects.

Below you will find a selection of breakthrough projects from the Leuven Climate City Contract. A full overview of all projects can be found in the magazine, which was published in spring 2024.

40 Leuven cultural organizations commit to climate action

On 19 May, 40 cultural organizations from Leuven endorsed the ten guiding principles for climate action within the Leuven Climate Contract. By doing so, they committed themselves to actively working towards a future-proof way of operating in the coming years, with a focus on climate, well-being, and societal impact. They follow in the footsteps of 29 Leuven-based organizations, companies, and institutions that had already made this commitment.
Through their pledge, the cultural organizations also emphasize another important point: the climate transition is not only about technology, energy, or infrastructure. Culture also plays a key role in shaping how people perceive societal change and envision the best possible future for our city.

Lawyers get to work on the Leuven Climate Fund

The Leuven Climate Fund is taking increasingly concrete shape. Together with the City of Leuven, investors, and project partners, Leuven 2030 is working towards a robust and future-proof framework for collaboration. The first pilot project is being prepared for investment and is expected to demonstrate that the fund can operate successfully.

Leuven 2030 brings partners of the Leuven Climate Contract together

In October, Leuven 2030 will once again bring together the partners of the Leuven Climate Contract for an afternoon of knowledge exchange and in-depth discussion. During a series of thematic sessions, participants will explore topics such as Leuven’s heat transition, mobility, solar energy, building renovation, and sustainable food systems. The connection between these themes and Leuven’s ambition to become a European Capital of Culture will also be discussed.
Participants will return to their organizations with new insights, practical examples, and valuable connections that can help them advance climate action and sustainability initiatives within their own work.

‘Impact Estimator’ to calculate the societal benefits of Leuven climate projects

How much value does a euro invested in climate action generate? With the Leuven 2030 Impact Estimator, we make the real benefits of climate investments visible. These benefits go beyond reducing CO₂ emissions and include improvements such as healthier air, greater energy independence, climate resilience through heat mitigation, and job creation.
The tool helps us better assess which breakthrough projects within the Leuven Climate Contract create the greatest societal value. It provides a powerful decision-making instrument for policymakers and investors alike, while also serving as an inspiration for other European cities.
In the coming months, we will focus on putting this tool into active use.

Message to Europe: Leuven and other European cities can provide strategic protection

From 6 to 8 May, more than one hundred European cities gathered in Vilnius for the annual NetZeroCities conference, the European platform that supports the ‘Mission Cities’, the more than one hundred cities committed to accelerating their transition to climate neutrality. Leuven was present not only as a participant, but also as a frontrunner.
Together with several other cities, Leuven used the conference to issue a clear call to Europe: cities want to do more than simply implement policies; they want to help shape Europe’s climate-neutral future. This call was set out in a joint position paper that received broad support. Leuven 2030 and the City of Leuven took the initiative in drafting the document and sought out like-minded cities in Vilnius that shared the same vision.

A step closer to a Leuven Climate Fund

On 11 June, we brought together 46 investors, financial institutions, and fund managers at De Hoorn in Leuven. The aim was to explore a new type of fund that intrinsically links financial and societal returns. This initiative was organised in collaboration with the City of Leuven and Impact Finance Belgium.
Many financial players have been working on their sustainability strategies for some time, but this was the first occasion on which so many organisations actively took up the challenge of jointly exploring how such a new model could be made possible. It marks another important step towards the establishment of a Leuven Climate Fund.
More than 20 participants signed a declaration of intent to support the creation of the fund, sending a clear signal that there is strong enthusiasm to move from ambition to concrete action.

Publication of the Leuven Climate Contract magazine

The Leuven Climate Contract, which we officially submitted to the European Commission in November, was transformed over the past months into an attractive magazine. It brings together the stories behind the breakthrough projects and commitments, complemented by in-depth interviews, insights from members of the Leuven network, an overview of the signatories of the guiding principles, and a first look at the financial strategy, the Leuven Climate Fund, that will help turn the ambitions of the Leuven Climate Contract into reality.
On our website, we highlight 10 breakthrough projects led by different partners. They offer an insight into the wide range of initiatives through which the Leuven network is working to implement the Leuven Climate Contract. These are just a selection of examples: significant progress is also being made across many other projects. Communication about those projects is led by the partners responsible for them.
