The 1957 Treaty of Rome established the four freedoms - the free movement of persons; the free movement of goods; the free movement of services; and the free movement of capital.

These initial four freedoms reflected the needs of the prevailing industrial economy and helped spur the creation of the 1992 single market project. Today, we are on the path to create a knowledge-based economy. Europe's heads of states acknowledged this shift in 2000 when they launched the Lisbon Agenda for growth and jobs. Now, it is time for the European Union to add a Fifth Freedom to meet the needs of the knowledge economy.

A c
onstructive and creative debate has opened about the meaning of the fifth freedom. In a speech given in April, 2007, Science & Research Commissioner Janez Poto─Źnik emphasised the importance of the European dimension to research. Later that year, the European Commission published a new strategic report, adding high speed Internet and innovation coordination. Last year Information Society Commissioner Viviane Reding published a Communication on the Future of the Internet, which put openness at the heart of her future Fifth Freedom agenda.

For Google, Europe's Fifth Freedom should mean freedom of knowledge to enable collaboration and strengthen community, not only to drive jobs and growth but also, for example, to address climate change and to modernise our democracies.

We've been discussing our first thoughts on the Fifth Freedom with policy makers over the last few weeks. Their suggestions have helped us refine our analysis. Among the thin
gs we now suggest is testing new innovation mechanisms, like awards and public procurement, prioritising opening up and mapping information that can fuel innovation in Green ICTs and re-thinking the barriers to entrepreneurship - collaboratively - with entrepreneurs in the driver's seat.

Collaborative innovation should also be the cornerstone of public policy. Today, we are making our revised contribution - version 1.5 - available. We would be delighted to receive your comments, as we continue to develop this document over time.

This is not the last you will hear from us on the subject. We plan to blog about these issues over the coming months and will continue to discuss our vision.
