 Rio de Janeiro 's bidding process began on July 28 , 2006 , when the Executive Council of the Brazilian Olympic Committee ( COB in the Portuguese acronym ) met to consider the possibility of nominating a Brazilian city to host the 2016 Summer Olympics and Paralympics . This meeting was prompted by the fact that several cities in the world demonstrated interest around the election , some having already announced their bidding intention . Then a technical analysis was commissioned by COB to evaluate the conditions of the city , unveiled on August 25 , 2006 . A week later , on September 1 , 2006 , the COB 's Annual Assembly decided by acclamation that Rio de Janeiro would be the Brazilian representative seeking to host the Olympic and Paralympic Games in 2016 . The Assembly felt it was the only city in Brazil and South America which would possess Olympic @-@ level facilities ready for an Olympic and Paralympic bid , a legacy of its upcoming hosting of the XV Pan American Games in 2007 , later considered to be the best in history . Another positive aspect was that Rio de Janeiro could host all Olympic sports within the city limits , although the Olympic football tournament is hosted by multiple cities . The Brazilian government immediately expressed its support to the bid . Carlos Arthur Nuzman , president of COB , and César Maia , then Mayor of Rio de Janeiro , approved the decision , thus making the bid official .
