The paper examines the extent to which knowledge is relevant in determining climate policy in cities. 

For this reason, we test the proposition that specific measures for climate protection in public real estate management are taken according to predominantly shared beliefs. To determine why different measures are chosen in different cities, we present a case study that compares three major German cities. 

The results indicate that the perspectives from which decisions are made and the resulting climate policy in public real estate management varies among cities. In addition, the research suggests that shared beliefs have a high degree of significance in explaining the various outcomes. With these results, the paper contributes to improving the understanding of local differences in climate policy, including how institutionalized knowledge influences rational decisionmaking. For climate policy, these findings are important because the measures to reduce GHG currently have different effects on local real estate actors.
