He is co-author of different green roofs books and has been an invited speaker at congresses in Europe, North America and Asia in recent years. IGRA`s targets include the worldwide promotion of the ecological green roof idea, an international knowledge transfer in the field of green roofs and the stimulation of international standards for good practices and reliable green roof technology. One of IGRA´s main areas of work is implementing green roof policies on an international level.
