Data confidence level:
This FACT indicates the percentage of green star rated projects by the number of construction companies that operate within the respective Australian cities.
A Green Star project is one that has been certified under the Green Building Council of Australia (GBCA). The GBCA's Green Star rating system is awarded to projects that have been implemented with the aim of reducing their environmental impact. The project can be a building, a number of buildings, or a fit-out. The certification is given to both new projects and projects that have undergone extensive renovations. In real numbers, Melbourne and Sydney would certainly have the most green star rated projects, according to the GBCA. However, comparing the number of green-star projects against the number of construction companies, Canberra has the most, at 7.44 percent. At 1.95 percent, Hobart has the lowest percentage of construction companies that are green star rated.
