Costello is a GREEN SCHOOL! 

This program began as a grassroots initiative at Hartland High School in Livingston County in 2005. This effort resulted in Governor Jennifer Granholm signing Public Act 146 into law in May of 2006. Oakland County became involved with this program in the 2007-2008 school year, and awarded the Michigan Green School designation to 45 public and private schools during the first year. Oakland County had more schools participate than any other county in the state.

For the 2016-2017 school year Oakland Schools and Oakland County celebrated their BIG 10th Anniversary!  153 schools were designated a Michigan Green School. There were 30 schools that also received the special designation of Emerald status by successfully earning an additional 15 points for extra activities and 99 schools earned the Evergreen status, by participating in 20 or more activities.  The awards ceremony was held at Oakland Schools on April 26, 2017.
