How is the impact label constructed?

The impact label was created in collaboration with teachers from Breda university of applied sciences and NHL Stenden Hogeschool. With founding from CELTH.

The impact label is based on 32 questions a landlord has to answer for his accommodation. Of these, 1 question is about the energy label of the accommodation and 31 yes/no questions concern aspects such as building(s) & energy, waste & recycling, water, other contributions to biodiversity and local ecosystems and local community and destination. When the questions are answered yes, the accommodation receives x number of points. Below is which label belongs to which number of points.
