The U.S. band, which has sold 60 million albums since 1991, said on Monday it was investing $210,000 to plant trees in Washington State to soak up an estimated 7,000 tons of carbon dioxide linked to a 32-date 2009 tour.
"Pearl Jam is a band but we are also a business," guitarist and co-founder Gossard told Reuters in a telephone interview.
"We're seeing ourselves as a Washington business, a regional business that is acknowledging its carbon footprint and hoping to inspire other businesses."
Many leading musicians have sought to raise awareness about the risks of climate change, often by planting trees, and culminating in "Live Earth" concerts in July 2007 across seven continents.
But Gossard, 43, said celebrity-driven inspiration was often short-lived. "The idea of a celebrity is fantastic in terms of raising awareness for a day or a week, but it needs consistent business policy in the long term," he said.
He said there were good business arguments for investing in climate measures -- even though opinion polls in the United States show dwindling belief that mankind causes global warming. Carbon-capping legislation is stalled in the U.S. Senate.
"It's doable. It's not going to kill your company and if anything it will enhance your company's ability to sell whatever it is selling by being good stewards of the land," he said.
The move to cleaner and greener is all well and alive in the rock community these days. Jack Johnson's new tour is going to have its profits delivered back to community groups - some of which will no doubt be asking us to cut back on travelling hundreds of miles to see our favourite bands...
