What can be changed
This measures the share of residential surroundings covered by trees – from the satellite, weighted by the population of the same 100 m cells as the heat figure above. Both figures therefore apply to the same places and can stand side by side. Parks, cemeteries and gardens count. The city’s stock of street trees requires the tree register.
A heat action plan is documented for Chemnitz, but we did not find a published document: it is in progress, announced or adopted. Source: „Hitze in Chemnitz – Fachteil zum Hitzeaktionsplan“.
