How Nature Based Climate Tech Can Save Our Future Cities.

In recent years, research led by the EPA has uncovered the benefits of nature based climate tech, and the results give future cities a roadmap to reimagining how we can co-exist with nature and fight against climate change.


Green building policies and city-wide mandates are spreading across Europe and the U.S to implement living architecture to help offset carbon, improve energy savings, retrofit buildings, and prevent over-flooding in urban areas.


Let's explore how nature-based climate technologies will green our future and transform our cities.


Reducing Greenhouse Gas Emissions

According to a study of temperatures worldwide, the average temperature on our Earth has risen by at least 1.1° C (1.9° F) since 1880. What is more alarming, however, is the fact that the majority of this warming has happened since the mid-1970s, at a rate of approximately 0.15 to 0.20°C every 10 years.


This rapid warming within the last few decades can be attributed to a predominance of greenhouse gas effects caused by urbanization. The built environment is a primary contributor to climate change and is responsible for 30 percent of energy-related greenhouse gas emissions.


Additionally, a rise in building construction is destroying the world’s biodiverse ecosystems. This, in turn, increases the emission of carbon dioxide, which is a primary greenhouse gas. According to the Intergovernmental Science and Policy Platform on Biodiversity and Ecosystem Services, there is a clear connection between low biodiversity and climate change.


As cities get larger and the need for housing grows, the area available for greenery becomes increasingly limited. While an increase in parks or nature reserves within these urban areas is proving difficult, living walls are being favored as an effective and space-efficient solution.


This is because the plants in a living wall absorb and store carbon dioxide in vegetation and soils without sacrificing valuable ground space. This is known as carbon sequestration. In doing so, they can significantly reduce this primary greenhouse gas, along with the severity of the greenhouse gas effect.

Just 1m2 of living wall can absorb up to 2kg of carbon dioxide per year. An entire tree can absorb around just 5.5kg of carbon dioxide each year. The plants in living walls also remove harmful toxins from the air, such as nitrogen dioxide.


Considering living walls can span up to tens of meters when installed on the façade of a building, it’s easy to see just how beneficial they can be at alleviating greenhouse gases and improving global air quality when placed within cities all over the world.
