  29. 4thITU Green Standards Week ITU’s vision “The rational solution to citizens’ concerns regarding exposure to EMFs is to ensure that the actions of national regulators and network operators are accompanied to the greatest possible extent by transparency and communication with citizens. Compliance with international standards and associated reporting mechanisms assures citizens that regulators and network operators have complied with international best practices in deploying base stations, thereby safeguarding citizens’ health.” Malcolm Johnson ITU/TSB Director
