Personally, I don’t understand carbon neutrality. How deep does this rabbit hole go? If Google only buys and uses fully electric cars for street view and use only solar and wind to power them is that good enough? Does the manufacture of the car, batteries, solar panels also have to be carbon neutral? If not, can a company become carbon neutral by simply letting another company do the dirty work?
