Pearl Jam have invested $210,000 to plant trees in Washington in a bid to offset the carbon footprint left behind by their 2009 US tour.
The group's investment covers their own travel and hotel contributions, as well as the emissions by fans who travelled to dates on the 32-date jaunt.
As well as Washington, the band also want to build similar urban forests in Seattle, Kent, Kirkland and Redmond.
"Pearl Jam is a band but we are also a business," guitarist and co-founder Stone Gossard told Reuters.
"We're seeing ourselves as a Washington business, a regional business that is acknowledging its carbon footprint and hoping to inspire other businesses."
Gossard added that the sporadic support of musicians and celebrities to slow climate change was not enough, and that “consistent business policy” was needed.
Pearl Jam made a similar investment in 2003 and are continuing to look at ways to minimise their footprint.
As previously reported on Gigwise, the band are set to headline the Hard Rock Calling festival in London this summer.
