The Rock and Roll Hall of Famers have pledged $1 million to New York City's MillionTreesNYC, which will plant 10,000 trees to create new urban forests, according to a press release. The trio has also committed to making their final concert a benefit for NYC public television arts programming.

"We kicked off our very first American tour at CBGB's in 1978 and this summer, thirty years later, our journey will come full circle as we play our final show here in New York City," The Police said in a joint statement. "We are honored to partner with public television and have a deep respect for their commitment to arts and culture."

Details about the fund-raiser will be released at a later date.

Last week, The Police kicked off another round of North American shows, and they've got a dozen more dates across the US through the end of the month, including a two-night stand in Hollywood, CA. In early June, they'll jet to Europe for a month and then return stateside for their fond farewell, which comprises another 17 shows stretching from coast to coast.

Elvis Costello & The Imposters will fill the opening slot on the US outing, which is listed below. Overseas gigs can be found at The Police's website.

The band's reunion trek moved more than 2.5 million tickets in 2007, making it the year's top-grossing tour, according to a press release. Amidst all the hype, speculation had run rampant that The Police would record a new album, but the rockers quashed those rumors, telling various reporters they have no plans to work together once the tour wraps.

The Police released their last studio album, "Synchronicity," nearly 25 years ago. Sting, Stewart Copeland and Andy Summers celebrated their 30th anniversary last year with a best-of collection on A&M Records, and they reportedly have plans to release a live DVD comprising recent concert footage shot in South America.
