A couple of footprint calculator answers:
I suspect that this calculator won't produce a figure lower than 1 (less than one earth required to support everyone at this level of consumption) unless you are vegetarian and probably have no car.
It takes a lot of working through the tips at the end to get below 1, but that's kind of the point - so much of our impact is based on the big infrastructure-level stuff that we can't affect with our daily choices. It comes down to needing business and govt to see a public pressure to change. Sadly, in the current climate (no pun intended) that's getting harder and harder.
3.81 for me but heavily influenced by air travel for work (once a month in europe on average) and a lot of driving (mostly commuting). Not ideal by any means but I do what I can at home.
Technically, work flights shouldn't be included as they're bound up in your employer's footprint - they'd be passed on to the end consumer. Commuting journeys are as they're down to how far you decide to live from work. That said, if you can influence your employer to reduce the amount of flying you have to do (video conferencing etc), then do it.
Is that bad, I have no idea what 1.69 means?
If everyone on the planet lived in exactly the same way as you, how many planets' worth of productive land would we need? Worth bearing in mind that the current world population needs over one planet's worth right now, so we're building up an ecological debt. We (WWF) try to be constructive and positive, but there's some scary stuff going on behind that.
On Edukator's comment, it's designed to be fairly accurate for the middle of the population bell-curve - it's about giving people an indication of their impact. Its accuracy definitely drops rapidly if you've got a relatively low (e.g. you, by the sounds of it) or high (e.g. celebs/billionaires) footprint. There are calculators out there that give a much more consistently accurate answer, but they take ages to fill in and need you to start entering figures from bills and petrol receipts.
