The Sochi 2014 Olympic Winter Games was by far the Games that Oben felt he made his most important contribution. The Games organizers were faced with resistance from NGOs and civil society groups who were not happy with the location of some of the sliding venues, particularly the Bobsleigh venue. Oben led a UNEP expert team to review the location of the venue. The team and UNEP recommended to the International Olympic Committee that the location of the venue would pose serious challenges to the environment and migratory species (some of which were endemic). As a result of this recommendation, the venue was changed.

Theodore Oben subsequently led several UNEP expert teams to review progress on the implementation of the environmental commitments for the Games. He organized several rountable meetings between companies developing Olympic and tourism infrastructures around the Sochi Games and stakeholders to discuss cooperation on the preparations and staging of the Games.

He convinced all key stakeholders involved in the development of facilities in the Mzymta Basin – the main area that was heavily impacted by the facilities and infrastructures of the Games – to sign a commitment to work with all relevant stakeholders to restore the Mzymta Basin.

He subsequently led a UNEP expert team to develop GAP analysis and action plans on the restoration of the Mzymta Basin. The action plans were handed over to the Russian Government for implementation.
