The City of Mannheim approaches the EU-Mission “100 climate-neutral and smart cities by 2030” with deep motivation based on the systemic and political changes outlined in the “Mannheim Message” (need of Local Green Deals). The municipal council's decision to develop the Climate Action Plan 2030 with the targeted orientation towards the EU-Mission made the goal of a climate-friendly, climate-resilient and climate-neutral city, which is a role model for environmentally conscious action, a top political priority.

 

Mannheim is using the integrated approach of the LGD to reach its goal of climate neutrality by 2030. As a Local Green Deal pilot city, it combines and concretises the sustainability and climate goals set by the "Mannheim 2030" Mission Statement, focuses on a socially just transformation of a highly industrialized city, makes targeted use of funding and financing opportunities and integrates international commitments and networks in the process. The entire urban system is being developed towards this ambitious goal with the intention of improving quality of life in the city at the same time.

 

Mannheim has an innovative governance approach for localising the 17 SDGs based on the city's strategic goal and management system, which contributes to transparent, inclusive, responsive and effective decision-making for the climate-neutral vision. Mannheim aligns all projects with the city's sustainability and climate goals and links them to the budget. A new governance structure for the EU-Mission that started as an LGD project has since been transformed into a permanent matrix structure directly under the leadership of the Mayors Conference - the 100CNC/LGD transition team, which is driving the process to concretise the vision. 

Key Learnings

Collectively Enabling Effective Climate Investments - Mannheim ECT activity

To achieve climate neutrality, Mannheim is addressing a major bottleneck: the absence of strategic funding and capacity-building systems for climate investments. The COLL€CT project establishes a comprehensive framework for improving the city's ability to secure and manage funding sustainably. It not only addresses urban governance and capacity building in relation to funding, but also systematically identifies existing gaps and assesses innovative financing mechanisms to approach them. By leveraging the knowledge and insights generated by the project, it contributes to EU peer learning while also supporting stakeholders across urban society in their efforts to achieve climate neutrality. Objectives Improving strategic funding management of the city administration Improve access to public and private financing Build a Local Capital Knowledge Hub Investigate on local climate initiatives and innovative financing solutions Develop a project funding platform ECT = Enabling City Transformation

Committed to Local Climate Action Building - German cities pilot activity

How do you change the daily habits of an entire city? Three German cities formed a coalition to answer this question, recognising that consumption-based emissions —from food choices to mobility patterns to heating decisions—require far more than technical fixes. CoLAB created a shared framework called the "House of Change", combining physical transformation spaces, digital engagement tools, and new governance structures to make climate action visible, accessible, and social. Led by Mannheim, the project tested whether cities can shift behavioural norms at scale. The pilot involved Mannheim, Aachen and Münster. 

Mannheim City Lab on Social Innovation in Energy Transitions (SONNET)

In line with the city’s overall climate policy, the city of Mannheim developed and implemented a city lab ("living lab" approach) as part of the EU Horizon project SONNET. The city lab aimed at mobilising citizens for the development of the neighbourhood Neckarstadt-West, a neighbourhood with many residents with migration background, where language barriers posed a challenge to the city to engage with citizens for energy transition efforts. Whereas the Covid-19 crisis posed significant barriers to the original idea and scope of actions, the city still managed to implement diverse actions. The city lab entailed mobile participation/planning containers, gamification with apps, and explored measures for the neighbourhood such as energy role model flats, a neighbourhood fund (crowdfunding) for energy efficiency measures, and more. Towards the end of the project, additional funding from the German development bank KfW was acquired for a neighbourhood renovation management, which enabled a certain level of continuation of the activities. The overall impact lies in the social dialogue and processes that were strengthened and shaped, rather than measureable emmission recutions.

Mannheim, Germany case studies - Intelligent Cities Challenge

The Intelligent Cities Challenge (ICC) is a European Commission initiative bringing together 136 cities to achieve intelligent, socially responsible and sustainable growth through advanced technologies. This resources includes case studies from Mannheim, Germany related to: Using cocoa shells as a biomass fuel to reduce CO2 emissions Installing photovoltaic systems, heat pumps, and other renewable energy technologies

UPPER Project Hackathon in Mannheim

In the framework of the UPPER project we held a series of Hackathons asking innovators and entrepreneurs to come up with solutions to mobility challenges raised by the cities. The Mannheim Hackathon was held on 12-13 March 2024.  More information about the project here: https://www.upperprojecteu.eu/

Multi-Actor Collaboration and Private Sector Engagement in the Cities Mission

This report explores how five European Mission cities - Lund, Leuven, Mannheim, Milan and Bratislava - are using multi-actor collaboration and private sector engagement as core governance mechanisms for advancing climate-neutrality implementation. Building on the first edition of NetZeroCities case work on multi-actor collaboration, the report extends the comparative analysis to a second set of city cases and focuses on the practical governance arrangements, instruments and engagement processes through which cities seek to mobilise companies and other non-state actors around Climate City Contract implementation.
