Calculating the real cost of travel

that’s awesome! i wonder if they’ll make an interface that works with other browsers?

and i always wondered; when people make these equations — are they assuming you’re the only one on the plane? or is it just your percentage of the pollution from the flight/bus ride/etc.

i think that needs clarification.

This is four times now that i’ve come on your website in the last 3 days while searching google for absolutely unrelated things. Kinda funny. Keep up the good blogging!
