I should probably offset the long taxi rides to and from the airport, as well as the fairly long bus ride plus I'm fairly sure the bus was idling as it waited for enough people to arrive. But I'm not so keen on offsetting automotive sins as I have never owned a car and live downtown so that I (almost) never have to drive anywhere.
I was surprised that Google had bottled water. I don't know whether it's true that it takes "3 liters of water to produce one liter of bottled water" (Pacific Institute) but it certainly can't be good to raise a generation of people who think it's better to drink branded water out of a throwaway plastic bottle than to fill a glass from a tap or bend over a water fountain.
