A new sustainable way of building infrastructure. The solution is wood!
Through many innovations in engineered timber, the world’s first wooden skyscraper has emerged. The material used is cross-laminated timber. This type of timber is engineered wood- small pieces of wood glued together. There are three main types of engineered wood. The first one being glued laminated timber which is the most commonly used, Laminated veneer lumber (LVL) that has the same strength as concrete and the newest one is cross-laminated timber (CLT) .
Compared to traditional building materials such as steel or reinforced concrete, cross-laminated timber has many advantages over it, firstly being more eco-friendly by reducing carbon dioxide emissions, light-weight compared to other building materials thus being easy to transport resulting in low transportation cost, and being readily available  . According to the U.S. Department of Agriculture, a four-story building made of mass timber would save emissions equivalent to taking 500 gasoline cars off the road a year .
Currently, there are many wooden skyscrapers worldwide. An example is Mjös Tower in Norway’s Brumunddal has a height of 85.4 meters and is the world’s tallest wooden building. It is an 18-story building constructed by glue-laminated timber GLUAM that used CLT and LVL mainly, with concrete on the upper seven floors to prevent swaying in the wind and stabilize the pay scraper . It is also used in many other structures such as a 23-meter tower in Portland Oregon and in Quebec, Canada it was a key building material for the 160-meter long Mistissini Bridge .
In the past, it has been used in China to build Sakyamuni Pagoda of Fogong Temple build in 1056 and has a height of 67.31m (220.83ft) and has withstood several large earthquakes  .
