On Monday, the International Olympic Committee voted unanimously to add sexual orientation to the list of traits for which an athlete can not be discriminated against.
The recommendation was part of a 40-part initiative known as Agenda 2020, which aims to "promote the Olympic values" and "strengthen sport in society."
Recommendation 14 was to add sexual orientation to the 6th Fundamental Principle of Olympism, which currently reads:
"Any form of discrimination with regard to a country or a person on grounds of race, religion, politics, gender or otherwise is incompatible with belonging to the Olympic Movement."
The issue of LGB discrimination in the Olympics has been a hotly debated subject since the 2014 Sochi Olympics due to Russia's many discriminatory laws.
Not included in today's recommendation was the protection and inclusion of trans and gender-nonconforming athletes. Athlete Ally, an organization working to end discrimination against LGBT athletes, said that while the inclusion of the sexual orientation clause was progress, the failure to add gender identity in the 6th Principle means there is still progress to be made.
