GBTA’s Sustainability Committee leads, guides, and mobilizes the GBTA membership to collaborate on advancing standards and solutions to improve the sustainability performance of business travel across all three ESG pillars (Environment, Social, and Governance).

  • Leverage the committee’s expertise to be an incubator of ideas that provide visibility, education, tools, and resources for our members to expand the sustainability practices into travel policies and programs
  • Utilize GBTA’s history and unique position to play a legitimate leadership role to impact and facilitate effective sustainability change
  • Develop a roadmap for the future of sustainable travel and our communities by taking credible actions today to track, reduce and mitigate emissions from business trips.
  • Be the conduit between business travel buyers, suppliers, and intermediaries to create standardization for emissions calculations and unified sustainability recommendations.

Applications to serve on a Committee are accepted year-round and open to any GBTA member. Members serve 2-year terms running from Convention to Convention. Each Committee will be in contact shortly after an application is received. Based on the application, the Committee may either conduct an interview, hold the application or decline the applicant. Committees must maintain a 51% Direct Member and 49% Allied Member ratio. Fill out the committee application form below.
