Very well said.
I wonder (actually I really dont - it is clear that it doesnt) if 0 emission include also creation of silicon resin, PCBs, wiring, electricity,... And to back up parent claim - where where they produced?
I am not saying it is nothing - surely better than nothing - but it is "a tad" spitting into the sea.
The major footprint comes from heavy industry that is creating the materials so google can actually operate and if I would be sarcastic - they actually create a greater need for materials where its production produce large amount of emissions.
I would even claim, that they would do far more if they would stop showing ads. The electricity footprint on world wide scale must be enormous - not from google serving them but actually reaching destination and browsers processing them - and not all electricity is coming from "green" sources.
I can claim 0 emission for myself except from (sorry, I just had to say it :D), farting and breathing. But once I start to count in how my food was produced, how the goods I am using were produced etc. this is just not true. Anyway as a decades long vegetarian, strictly driven on public transport or bicycle (:D) I do my best here.
This is just publicity stunt from google PR and it doesn't really mean anything.
But looks like it worked. BBC cached it and is doing an article about it.
