Mr. Adam's "Beyond the Launch" leadership track will take place on Friday, October 6, from 9:00 - 10:30 AM.   WHAT: The Global Reporting Initiative's Conference on Sustainability and Reporting. The theme of this year's conference is Reporting: a Measure of Sustainability. More than 100 speakers representing business, civil society, labor and government from developed and developing countries will join executives from around the world - including board members, CEOs, COOs and CFOs - who are leaders in sustainability reporting. The Global Reporting Initiative (GRI) is a global voluntary network dedicated to the development and use of a sustainability reporting framework.   During this year's conference, the GRI will launch the new G3 reporting Guidelines. The new G3 Guidelines make reporting simpler, are better harmonized with the UN Global Compact and other tools, and make GRI reports more useful for investors and analysts, focusing on corporate governance.   TOPICS: Hyperion's Philippe Adam will be participating in "Beyond the Launch" leadership track, where he will address the impact of the G3 standards on industry and discuss best practices in implementing these new standards.   During this year's Technology Fair, Hyperion's Erik Thomsen will present, "Linking Sustainability Reporting and Financial Reporting." Many companies treat sustainability reporting as a separate process from their Financial Reporting. Some companies, however, are realizing the benefits of integrating these two processes. Mr. Thomsen will discuss the advantages of sustainability reporting, the benefits of integrating sustainability reporting with financial reporting and how companies can collect and distribute this information throughout the enterprise and beyond. Mr. Thomsen will address how forward-thinking companies are leveraging business performance management software to drive performance improvements by better aligning goals with metrics and increasing operational efficiency, while managing and reporting a responsible environmental policy.   WHERE: Hotel Okura Amsterdam, The Netherlands   For more information or to register go to www.grig3.org/.
