Charity projects that the band have been involved with include the collaboration with U2 ("The Saints Are Coming") to help raise money for musical instruments lost in Hurricane Katrina, and teaming with the Natural Resources Defense Council for the "Move America Beyond Oil" campaign and other environmental concerns.
In September 2006, Green Day teamed up with U2 and producer Rick Rubin to record a cover of the song "The Saints Are Coming", originally recorded by The Skids, with an accompanying video. The song is to benefit Music Rising, an organization to help raise money for musicians' instruments lost during Hurricane Katrina, and to bring awareness on the eve of the one year anniversary of the disaster. December 2006, Green Day and NRDC opened a web site in partnership to raise awareness on America's dependency on oil.
Green Day released a cover of the John Lennon song "Working Class Hero", that was featured on the album Instant Karma: The Amnesty International Campaign to Save Darfur. The band performed the song on the season finale of American Idol. The song was nominated for a Grammy in 2008, but lost to The White Stripes' "Icky Thump".
That summer, the band appeared in a cameo role in The Simpsons Movie, where they perform the show's theme song. Their version was released as a single on July 24, 2007.
