Quick answer：

Greening rooftops refers to the practice of creating vegetation on roofs. This can include the installation of a green roof, which is a roof covered with a layer of growing medium, plants, and a drainage system. A green roof has several benefits, such as improving energy efficiency, reducing stormwater runoff, and providing habitats for wildlife. A 'greening plane' could refer to the area or surface where this green roof is implemented.
