Well, about 6 months ago we signed up both of our cars plus household wastage on http://www.carbonneutral.com.au/ . Electricity is already on green. Would like to plug their site as it’s a great initiative!
If we weren’t renting I’d love to get a solar panel set up. However I settled for getting the air leakage into the garage fixed up; the gaps around this sliding door were big enough to poke a finger through. Got a door specialist to do a perfect install of air blockers to prevent this huge energy loss so that we’re all ready for the winter. It’s pretty mind boggling how bad the house construction standards are here in Australia. 
Also, just noting that Rudd’s first action as incumbent Prime Minister was to sign Australia’s ratification of the Kyoto agreement. Well done.
I’m happy and proud that Rudd finally signed Kyoto. This is a big and important step towards a more environmentally friendly Australia!
If you want to do more on your private end, check out the calculator at the Carbon Reduction Institute http://www.noco2.com.au. They claim to have the most comprehensive out there and I always offset my flights there (if I can’t avoid flying altogether). Similar to Carbon Neutral, only they do energy efficiency, waste diversion and renewable energy instead of trees.
