Del Carretto competed at the 2012 Summer Olympics in the Women's épée, but was defeated in the second round by reigning Olympic champion Britta Heidemann. Poor performances in the World Cup, her best placing being a quarter-final in Havana, caused a drop to No.27 in world rankings. 2012–13 was also a meagre year despite a bronze medal in the Xuzhou Grand Prix. Del Carretto then transferred to C.S. Aeronautica Militare, with Andrea Candiani as new coach, and moved from Legnano to Milan.
