After four years of building the largest annual public green exhibition in the world, Earth Day Texas will celebrate its fifth anniversary by expanding to a three-day event.

Earth Day Texas is an annual, outdoor festival seeking to elevate environmental awareness and influence the way Texans think, live and work. The family-friendly and free-admission event allows leaders in the corporate, academic and non-profit worlds to unite and show Texans how green lifestyle choices can lower their cost of living, improve their health and help save the environment.

The event will utilize approximately 750,000 square feet of both indoor and outdoor event space. EDTx’s footprint will easily accommodate the 1,000 exhibitors and 70,000 guests anticipated to attend this year’s event.

The heart of the festival is the Eco Expo where exhibitors will use their presence to promote their achievements as green leaders, and teach attendees how to take environmentally responsible action by better utilizing available resources, switching to eco-friendly products or joining their organizations.

EDTx will open its exhibit and event spaces to professionals and the public at 10 a.m. Friday, April 24. Programs that day will cater to the business and civic communities in particular, increasing EDTx’s educational reach while maintaining the popular public show on Saturday and Sunday.

Confirmed speakers include Dan Patrick, Texas lieutenant governor; Joe Quinlan, managing director and chief market strategist of U.S. Trust; Bjorn Lomborg, author of The Skeptical Environmentalist; and Ryan Sitton, Texas railroad commissioner.
