Human rights concerns expressed by Amnesty International and politicians in both Europe and the United States were considered by the delegates, according to IOC Executive Director François Carrard. Carrard and others suggested that the selection might lead to improvements in human rights in China. In addition, a number of IOC delegates who had formerly been athletes expressed concern about heat and air quality during the Games, considering the high levels of air pollution in Beijing. China outlined plans to address these environmental concerns in its bid application.
