Not...Thanks for your comments Robert and pedaller. Note that offsets doesn't necessarily mean planting trees - it could be investment in renewable energy projects or energy efficiency programs, for example. (Using your suggestion, pedaller, it could even be something like NSW Buses earning credits from changing their buses from diesel to natural gas and/or ethanol - although I agree with you they shouldn't need this encouragement!)David Jefferyhttps://www.blogger.com/profile/11826563619710355534noreply@blogger.comtag:blogger.com,1999:blog-19408890.post-1143930394705479492006-04-02T08:26:00.000+10:002006-04-02T08:26:00.000+10:00I think Robert in the comment above makes some ver...I think Robert in the comment above makes some very valid points. I would also add that planting trees requires arable land, that in Australia is already at a premium, whether for housing, food production or maintenance and protection of the environment. At some point in the not too-distant future, there will not be enough land available to feed the population and off-set its cabon emissions in this way.<BR/>The second point I would make is that Australians pay a lot of lip-service to the environment, but in reality do very little to susport ecologically-sustainable initiatives. The latest news that NSW is about to buy 255 new buses, a combination of natural-gas and deisel-powered buses is just one such example. Surely now is the time to introduce ethanol-powered buses onto our roads, the technology is now over a decade old, has been tried and tested in numerous countries, reduces NOx and particulate emissions .... and would give our pilot ethanol producers soemthing to do with ethanol they are making!Jhttps://www.blogger.com/profile/07546908073918671511noreply@blogger.com
