@msolga,
Not trying to be an apologist for the Rudd govt's recalcitrance but...
It strikes me that if people really gave a rat's ass about carbon footprints they could do a lot to cut their emissions by their own behaviours, like....
Use public transport more often
stop using incandescent bulbs
install solar panels
pay the green surchage on their power bills (if it's an option)
Turn their non essential appliances off a the wall when they're not in use
Get a more fuel efficient vehicle
Walk to the corner shop or at least turn your engine off once you're there (pet peeve)
Plant some goddam trees!
Buy local produce and eschew the fruit and veg chains.
Buy things with no packaging (especially avoid plastic packaging)
Eat kangaroo and avoid beef
Vote with your feet!
Just getting off high horse now - ooh, saddle sores.
