According to Archinect, LEED Gold and Platinum ratings have been surpassed by Protactinium, which provides points for including cute kittens, puppies and baby seals.
"LEED has unveiled a new level of certification, Protactinium.
In order to qualify for the standard, building designers must commit to a lifetime of celibacy and staff the building exclusively with doe-eyed orphans from third world countries. The building must be a net CO2 sink, producing more oxygen than it consumes. Any bamboo used in construction must be certified panda-free. In the event that straw bale construction is used, the straw must be free-range, sustainably harvested straw.
The building must also levitate above the ground to preserve the site for future use. Only free-range, sustainably harvested electromagnets may be used to levitate the building. The electromagnets should also give back 10% of their energy to levitate doe-eyed orphans in third world countries." ::Archinect
