CO2 accounts for about 76 percent of total greenhouse gas emissions produced by humans
Rise in global Temperature
Increase of respiratory deseases
CO2 concentration in the atmophere from 1750 to 1800 was around 278ppm
CO2 concentration in 2021 was 417ppm...
A Call to Action
Sustainable Initiatives and Reduction Policies
The global policy is to become carbon neutral by 2030, 2035, 2050, 20etc...
Is this enough to compensate 3 centuries of polluting?
CARBON NEUTRAL IS NOT ENOUGH
Carbon negative as an industry standar
Since 1750, human activity has increased CO2 emissions by 50%
If we were to stop polluting immediately, we would still need to remove CO2 that is presently in the atmosphere
For this, we need to:
Plant 1 trillion trees
10 billion acres of land
4 times the size of the USA
Is Nature the Answer?
Nature based solutions are alternatives that can speed the natural carbon sequestration process
Construction has a great incidence on the total production of CO2 emissions, therefore we must change the way we approach the built environment.
The urban landscape must help to capture CO2 while providing comfortable and flexible housing that reacts to societal changes.
A New Co-Housing Typology
Hybrid buildings have proven successful in many contexts. Those who combined housing, commerce, and services for inhabitants have a tendency to be more resilient towards change.
Carbon Capture Towers are co-housing buildings that address housing needs and provide communitary services, such as: urban farming, daycare, shared kitchens. As well as, using carbon capture technology to clean the atmosphere, balance the heating necessities and generete Energy / Revenue from the byproduct, the Micro algae.
Where to Locate Carbon Capture Elements?
Identify the main pollutants and their impact on a city's overall CO2 emissions, while
taking into consideration the heating and cooling for indoor spaces (a greatly overlooked source).
The carbon capture elements should take wind direction into consideration and release the filtered air at street level in order to get direct benefits for the system.
How Many Towers Are Needed?
We have developed a method to visualize the theoretical number of towers needed to absorb what is emitted.
Annual greenhouse scope 3 emissioned gases are quantified from a city's official monitoring data.
Currently a metric cube of photobioreactors has the capacity to absorb 1.82 Tonnes of CO2 per year.
A 21 story Carbon Capture Tower with 30% of its facade surface as PBRs, absorbs 467 Tonnes.
Three Scenarios where chosen to demonstrate the relation between pollution, population, and the Carbon Capture Towers. Seoul Being the most polluted needs 325, 21-story capture towers to compensate its annual CO2 emission.

In the urban Frabic
Carbon capture systems need to be extended to urban spaces. Therefore, urban furniture will be placed near polluting elements, such as streets and highways, to purify the air and generate biomass.
The existing building can be intervened to have carbon capture technologies, utilizing the biomass market for energy production, thanks to photobioreactors. Along with the new carbon capture towers they become a network that will lead us to be carbon negative.
