Problem
Climate Change is Intensifying Urban and Environmental Vulnerabilities in Developing Nations

Developing countries face compounding environmental challenges due to rapid urbanization and climate change:

* Rising temperatures and frequent heatwaves are increasing energy demand and health risks.
* Air pollution from fine dust (PM2.5, PM10) is severely impacting public health.
* Water scarcity and polluted runoff degrade land and communities.
* Urban areas lack green infrastructure to absorb carbon, retain water, and support biodiversity.
* Local governments often lack access to proven, low-cost, and scalable climate solutions.

These challenges demand technologies that are not only effective, but also easily transferable, resource-efficient, and capable of being operated by local communities.
Solution
Supergreen – A Scalable, Low-Carbon Vertical Garden System Tailored for Local Deployment

Supergreen, developed by CMI Corporation (Republic of Korea), is a modular, nature-based technology that transforms vertical surfaces into carbon-absorbing, water-managing, and biodiversity-restoring infrastructure.

Unlike conventional greening approaches, Supergreen is designed for cost-effective transfer to developing countries and ensures adaptability to diverse local conditions.

Key Features:

* Modular, Prefabricated Structure: adapts to buildings, fences, and freestanding structures. Locally fabricable using simple tools and training.
* Soilless Root-Control Planting System (Patented): ensures plant survival with minimal water and maintenance. Prevents root rot and allows for edible or medicinal plants.
* Smart Environmental Response (Optional): IoT sensors enable real-time monitoring of CO₂, PM, humidity, and temperature. Supports national climate tracking systems when needed.
* Stormwater and Water Recycling Function: captures and filters runoff up to 5 liters per minute, removes 82% of pollutants, and reduces heat transfer by 23%. Suitable for LID (Low Impact Development) integration.
* Off-Grid Ready: operable in remote or informal settings with low energy needs and solar compatibility.

Supergreen is not just a product - it is a climate adaptation platform that can be delivered alongside local training, certification programs, and community employment models.
Performance and impacts
Verified by National Testing and Real-World Implementation

Supergreen has been tested and certified by Korean Conformity Laboratories (KCL), Public Procurement Service (PPS), and SHCC.

Key performance metrics include:

* Carbon Absorption: up to 50 ppm per square meter per hour.
* Fine Dust Filtration: removes up to 120 micrograms per square meter per hour (PM2.5 and PM10).
* Temperature Reduction: reduces surface temperatures by up to 4.2°C.
* Humidity Stabilization: maintains relative humidity between 60% and 65%.
* Water Runoff Management: retains up to 5 liters per minute of runoff and removes 82% of pollutants.
* Plant Survival Rate: verified 99.9% survival in a 3-year real-environment pilot in Songdo, Korea.

Socio-Economic Impacts:

* Facilitates green job creation through local technician training.
* Enhances climate resilience in public spaces such as schools, clinics, and housing.
* Supports alignment with SDGs, NDCs, and GCF reporting through measurable environmental data.
Other data of interest
* Recognized as a Government-certified Innovative Product by Korea PPS (2024).
* Deployed at more than 70 public sector sites, including National Assembly offices.
* Winner of the Good Design Award (Ministry of Trade) and listed as a Green Procurement Priority Product.
* Includes an educational component via a Vertical Garden Specialist Certification Program.
* Fully aligned with UN SDG goals:

* SDG 11: Sustainable Cities and Communities
* SDG 13: Climate Action
* SDG 6: Clean Water and Sanitation
* SDG 15: Life on Land

"Supergreen offers more than greenery - it offers a replicable, inclusive, and evidence-based pathway for developing nations to achieve climate resilience and sustainable development.“
