Accor said the partnership signalled the group’s values as an open and inclusive company to LGBT+ communities.
John Tanzella, president of the IGLTA, said the association has "long admired" Accor’s commitment to diversity, equality and inclusion.
"Accor’s commitment to creating safe, welcoming experiences for LGBTQ+ travellers and to championing diversity within their team perfectly aligns with IGLTA’s mission and the work of our global partners."
Steven Daines, chief talent and culture officer for Accor, added the company was "immensely proud" to make the pledge and join with other partners.
