Background and objective: Carbon dioxide (CO2) is a common indoor air pollutant that can lead to respiratory issues, impaired cognitive function, and increased absenteeism. Plants play a key role in CO2 absorption through the process of photosynthesis,which is influenced by light intensity. This study aimed to assess the potential of plant species for CO2 reduction under different light conditions, providing baseline data to optimize their effectiveness in improving indoor air quality. Methods: Six plant species, including three evergreen broad-leaved plants (Pittosporum tobira (Thunb.) W.T.Aiton, Camellia japonica L., Viburnum odoratissimum Ker Gawl. ex Rümpler var. awabuki (K.Koch) Zabel ex Rümpler) and three foliage house plants (Alocasia sinuata, Monstera deliciosa, and Epipremnum aureum) were selected to evaluate their CO2 reduction ability under four different light intensities (10, 40, 80, and 160 μmol m-2 s-1). The plants were exposed to light for 11 hours, followed by a 11 hour dark period. A CO2 cylinder was used to introduce CO2 into the test chamber, and the CO2 concentration inside the test chamber was recorded every 10 minutes over a 22-hour period. Net photosynthesis was also measured for each plant species. Results: The CO2 reduction capacity varied among plant species and light intensities. All six plant species exhibited thehighest CO2 uptake at 160 μmol m-2 s-1, with uptake decreasing as light intensity decreased. Light intensity had a significant impact on the plants’ CO2 reduction ability, and CO2 absorption continued during the dark period. Among the six species,Monstera deliciosa and Epipremnum aureum demonstrated the highest CO2 uptake. Conclusion: Plants require adequate light intensity for effective CO2 uptake, making it crucial to examine their ability to assimilate CO2, as plant species that emit CO2 can have a negative impact on health. This will help identify which plant speciescan absorb CO2 without raising CO2 levels, especially in indoor environments where low light conditions are common. This study offers additional insights into the CO2 absorption capacity of plants, enabling landscape researchers to select suitablespecies that contribute to balancing and reducing CO2 concentrations in indoor environments. Further research is necessary to determine the optimal light levels and the right plant species for enhancing CO2 reduction effects in plants.
