Finnish shopping centre developer Citycon announced on Wednesday that it has launched three pilot projects in sustainable construction. In a statement, the company said the move is aimed at evaluating 'the implementation of development projects comprehensively from the viewpoint of sustainable operations, and to systematise pro-environmental practices'. The projects are the development of the Liljeholmen shopping centre in Stockholm, the extension to the Rocca al Mare shopping centre in Tallinn and the refurbishment of the Trio shopping mall in Lahti. Citycon is also seeking international environmental rating for its projects.
