Assessment of Carbon Dioxide Reduction and Air Quality Improvement through Rooftop Farming in Urban Areas

Urban Farm DB summary

This study assessed carbon dioxide reduction and air quality improvement through rooftop farming in urban areas over five years (2021-2025). It observed lower CO2 concentrations in rooftop farming areas compared to non-vegetated urban areas, where CO2 levels were recorded at 449 ppm in the township. Dense plant growth on rooftops reduced CO2 by absorption during photosynthesis, contributing to fresher air and improved environmental quality.
