Not as much as I'd like to be at the moment I feel like I dont' have time to do anything extra!!
I use Mooncup / CSP part time (finding it really hard with work and having a loo with no basin right in the middle of the house!)
We recycle
Grow some veg (need to get better at it - I kill a lot of things

)
As of yesterday use homemade dishwasher powder!
We don't have a dryer (even though it kills me some days!)
I drive a small diesel car that can do 1000 kms to the tank (even more with 100% highway)
We don't heat the house as with the high ceilings it would be so wasteful / expensive / un-enviromentally friendly - just put a jumper on and use blankets when sat watching TV.
Use no spray cans other than spider / bug / cockroach killer
So clearly there are a huge number of things I can still do! We intend to have a lot more going on when we own (eg compost / solar energy etc), it is hard to get sorted in a rental but we can't afford to at the moment

@littlesez I've always been a sweaty Betty and the only one that works for me is Mitchum which is roll on - might be worth a try for you! I have tried all the 'natural' ones and just end up with BO and I'm not quite that crunchy
