Vishal, I really appreciate your articulate response on this-- my rule of thumb has been to try to do things the way they used to be done-- as much as one can in a modern world. Designing buildings suited for their climate with proper passive systems, reusing what can be reused, incorporating alternative or renewable energy systems when applicable, are always on the design table as an architecture practice. However, I'm sure I fall short of a zero footprint every time I drive to work or take a plane
I plan to take the quiz (though I've always tried to offset my carbon footprint with a sense of humor) because the questions may give me a new awareness of something I hadn't yet considered-- and of course I might offer it as a link on my blog for those so interested.
And doesn't carbon trading seem a bit too much like buying indulgences from the 14th C?
