Pearl Jam pledge green donation

Pearl Jam 's current world tour ends in November

Pearl Jam are to donate $100,000 (£54,500) to environmental groups as part of an effort to offset carbon emissions the band churns out on tour.

The band has been tracking emissions from vehicles and venues to estimate its contribution to global warming.

Band members said this was the latest move in its "ongoing efforts" to advance clean renewable energy.

Pearl Jam emitted 5,000 tons of carbon on its last tour, guitarist Stone Gossard told a Seattle-based newspaper.

"We can get a really relatively accurate picture of what that looks like over a year, and it's a considerable amount of carbon," Gossard reportedly told the Seattle Post-Intelligencer.

Cascade Land Conservancy and EarthCorps - which work to protect and replenish forests - are among nine organizations Pearl Jam chose to receive donations.
