I guess I'm rather environmentally friendly - I cycle around 200km per week (but not as a mode of transport), I walk to school which is 3.2km both ways & if I need to go somewhere I take public transport or ride my bike.
I must admit the cycling in Brisbane is at best, lousy - despite riding at 5:30 in the morning traffic still poses a problem if you're riding by yourself. We do have a lot of bike paths on roads but that's just a politically correct name for 'parking lane' as cars can and do legally park on them.
Generally cycling is pretty good in groups as cars will normally give you a whole lane - and will not cut you off and even though there are a few dedicated bike/ pedestrian trials none of them compare to the ones in Toronto and Europe I've been to.
As for pollution in Brisbane it doesn’t seem to bad but our government has just completed a half a billion dollar plan to encourage public transport, like building a rail line to the airport, putting in bus lanes etc. and now our government has and is doing a 500million dollar plan to make non-public transport easier – like building a sub-river tunnel and turning the bus lanes into traffic lanes etc.
I think they need to build a really good public transport system and then just gridlock ordinary traffic till the point where people will have to use public transport
