I read somewhere they are planting one tree per every co2 equivalend produced extra by the tour. It does not take much to take care of the environment. Only a little bit of concern. By the way it is 127 trucks not 60 on the tour now.
I have to remind you that the Stones did a free concert in Feb. 2003 Los Angeles just on this case. See IORR news of Dec. 23 2002:
Staples Center LA free concert Feb. 6
NRDC (the Natural Resources Defense Council) announced today that the Rolling Stones will perform a special free concert to raise awareness about global warming on February 6, 2003 at Staples Center in Los Angeles, CA, USA. Fans can enter a sweepstakes to win two free tickets by completing the entry form at the NRDC Stones Concert pages. For more information see NRDC presents the Rolling Stones. Also, see the Reuters report.
