The new combined Sustainability and Annual Report released in September 2011 by FMG, Munich Airport's operating company, has received plenty of favorable attention. With this first "integrated report", Munich became the only airport in the world to gain the highest possible rating, Level A+, from the Global Reporting Initiative (GRI), which evaluates the transparency and quality of such documents. On the strength of this highly rated publication, Munich Airport is now taking part in a global pilot project for integrated reporting conducted by the International Integrated Reporting Committee (IIRC). The project is intended to produce guidelines for integrated reporting.
