Based in Chicago (the birthplace of the skyscraper), the CTBUH is the world’s leading authority on tall buildings. For over 50 years, they haven't just been measuring height; they’ve been defining the future of how humanity lives vertically.

The answer is the .

When you look at a city skyline—whether it’s the sleek spire of the Burj Khalifa or the twisting silhouette of Shanghai Tower—you are looking at a physical manifestation of data, safety standards, and innovation.

Here is why this non-profit organization matters to everyone who lives in or designs a city. If a building claims to be the tallest in the world, it has to go through the CTBUH. They are the official scorekeepers of the skyline.

The CTBUH stands as the referee, the historian, and the innovator. Whether you love skyscrapers as art or hate them as giants, the Council ensures that when we build for the sky, we don't forget the ground.

But who decides what a "supertall" is? Who tracks the race for the "World’s Tallest"? And more importantly, who ensures that as we build higher, we build smarter?
