The idea of ​​the architectural company Skidmore, Owings & Merrill (SOM) is that the buildings, in addition to their primary purpose, also contribute to environmental improvement. The project they presented puts sustainable construction in the foreground that provides an answer to the problem of urban environments and the growing number of buildings that are causing carbon dioxide increases and the greenhouse effect. The fact that the construction sector generates almost 40 percent of all global carbon emissions also contributes to the bad situation at the global level. It is predicted that the number of inhabitants will grow, which further leads to the fact that by 2060, another 230 billion square meters of new buildings will be needed.

Accordingly the new facility concept should transform the built environment into a CO2-absorbing environment like trees do. The prototype of the multi-storey building was unveiled at the recently concluded United Nations Conference on Climate Change in Glasgow “COP26”. The proposed tower is called an “urban redwood” because it mimics a tree. It captures carbon, purifies the air and regenerates the environment, creating a resilient urban environment. An ambitious proposal implies the creation of an “urban forest” or an environment with many such towers.

This sustainable solution could have a far-reaching impact, with the potential to create a circular carbon-absorbing economy. The proposal brings together different reflections on sustainable design, the latest innovations and technologies in order to create objects that will heal the planet. A holistic approach to optimizing building design, minimizing materials, integrating biomaterials, advanced biomass, and carbon capture technology achieves a significant reduction in carbon compared to the separate application of these techniques.

The concept has been developed so that it can be applied and adapted to the needs of any city in the world, with the potential for positive impact in any construction. These strategies can also be applied to buildings of all sizes and types. The prototype is actually a high-rise building that can collect as much as 900t of carbon per year, which is the same as it gathers 48,500 trees. The project includes nature-based solutions and materials that use far less carbon than conventional options and absorb carbon over time.

The solution is promising for the reason that it provides buildings that absorb carbon. In this regard, SOM claims that after 60 years, the prototype would absorb up to 400 percent more carbon than could be emitted during construction. Captured carbon can find application in various types of industries. If every city around the world built urban redwoods, the built environment could remove up to 14.5 billion tons of carbon from the atmosphere each year.
