It is clearly obvious that the CN Tower is the tallest building in the world. Why does the Council not recognize it?
The CTBUH tallest lists only recognize buildings not towers. A tall “building” can be classed as such (as opposed to a telecommunications/observation tower) and is eligible for the “Tallest” lists if at least 50% of its height is occupied by usable floor area. Therefore our lists do not include structures such as telecommunications towers and viewing towers. For more on this, see here.
