Characterised by its proximity to two rivers, the Rhine and the Neckar, as well as its heavy industry, the City of Mannheim in south-western Germany faces an urgent climate challenge. The city has committed to becoming climate neutral by 2050 and is looking into whether this goal can be achieved even sooner. The City of Mannheim is taking on this task, for example, with its Climate Action Plan 2030, climate impact adaptation measures and the provision of funding in cooperation with the Climate Action Agency. Together, they offer consultation, subsidies and a newly created City Lab where residents can get involved in the decision-making process.
