Vivawest, the Duisburg-based housing company, has announced plans to make its heating systems carbon-neutral by 2045. The company has not yet published a detailed roadmap or cost estimates for the conversion. Given the scale of Vivawest's portfolio and the 22-year timeline, industry observers question whether the target is achievable without substantial public funding. The announcement comes as German housing associations face mounting pressure to decarbonise aging building stock amid stricter climate regulations.
