Carbon garden in Delhi uses plants, algae, and fungi to sequester carbon and improve urban air quality

A new carbon garden at Delhi University uses a curated mix of plants, algae, fungi, and microorganisms to filter pollutants and sequester carbon in a small urban space. The garden includes fast-growing trees, native canopy builders, and microbial life that break down toxic gases. Early measurements show lower AQI and PM levels inside the garden compared to nearby roads. The model is designed for easy replication in schools, residential complexes, and office campuses. The Central Industrial Security Force is already building 44 carbon gardens across three Indian states. Experts caution that plant selection should be based on local ecology to avoid harming native biodiversity.

Interesting to see a real world carbon sequestration project that works at a small scale. The AQI data is promising but I want to see the full independent assessment before getting too excited.

Agreed. The informal study is a start but we need peer reviewed numbers on actual carbon stored per square meter. Still, 44 gardens in the pipeline is real deployment.

CISF building them across three states gives this some institutional weight. If the military police force is adopting it, the cost per garden must be low enough to scale.

The temperature drop of 4C inside the garden is notable. Urban heat island effect is a real grid problem during peak summer. If these gardens can reduce cooling demand even a little, that is a grid benefit too.

The key question for me is carbon accounting methodology. Are they measuring soil carbon, biomass, or just air quality co benefits? Without a standard metric it is hard to compare to other sequestration projects.
