Yes, but consider the big picture: "Boeing's 20-Year Forecast Predicts World Fleet Will Double in Size" http://www.aviationtoday.com/the-checklist/76670.html# So as with the native plants in landscaping issue, taking the train would be a largely symbolic gesture, not one that could help mitigate, in any mathematically meaningful way, the expected near doubling of CO2 emissions from passenger jets over the next 20 years. Even the newest jet models are only slightly more fuel efficient than the old models, hence their CO2 emissions are only a slightly lower. Paul Cherubini El Dorado, Calif.
