The Green Meeting Industry Council and the International Association of Professional Conference Organizers have joined the Convention Industry Council.

The CIC, an Washington, D.C.–based umbrella organization for the many groups that represent the meetings, conventions, and exhibitions industry, is now 33 associations strong.

Portland, Ore.–based GMIC was established in 2003 to promote environmentally responsible strategies for meetings and events.

IAPCO, celebrating its 40th anniversary this year, represents professional conference organizers in 26 countries around the world.

“International expansion and green events are extremely timely issues for CIC and the industry as a whole. We welcome these organizations and look forward to their participation and dialogue,” said Brenda Anderson, chairwoman of the CIC Board and CEO of the Society of Incentive & Travel Executives, in a statement.
