The Global Standards Collaboration (GSC) is an initiative of the ITU, ETSI, the United States' Committee T1 and the Japanese TTC to promote efficiency in international standardization activities.

GSC provides for the regular exchange of work programs and other information in a number of agreed high-interest technical areas, and has attracted a growing number of other participants from around the world.
As its name implies, its goal is to promote global standards in these areas of common interest.

The GSC does not have a permanent secretariat.Each GSC meeting is hosted by one or more of the Participating Standards Organizations (PSOs).The host is rotated so all PSOs and the ITU have an equal opportunity to host the event. The host provides a secretariat to manage the particular event.GSC has evolved over the years to incorporate new PSOs and Observers.

The mandate of GSC is to provide a venue for the leaders of the PSOs and the ITU to:

• Freely exchange information on the progress of global standards development and the state of the global standards development environment;
• Collaborate in planningfuture standards development to reduce duplication;

• Support the ITU as the preeminent global telecommunication and radio- communication standards development organization.

The Members of GSC are the PSOs and the ITU.

The PSOs are recognized or accredited to write (tele)communications and /or radio-communications standards in their area of practice, and/or are national or regional consensus development organizations that input to the ITU or use ITU outputs, and are working on similar areas of standardization. That is, the PSOs are by definition standards organizations that potentially exhibit a high degree of overlap in their work programs.

New PSOs may be added by a consensus decision of the existing GSC Members.
