一项分析研究了利用室内植物减少二氧化碳的可行性。[1] 人类每天产生约1公斤二氧化碳，[1] 植物需要通过光合作用将其转化为氧气。[1] 理论最小能耗仅为132.5瓦，[1] 但考虑植物实际效率后需要918瓦。[1] 现实中则需要5000-10000瓦的LED照明设备才能满足植物光饱和点约52瓦/平方米的需求。[1]
实现这一目标还面临其他技术障碍。[1] 所需最小植物叶面积达到17.6平方米以上，[1] 且每天必须生长并移除4.6公斤新植物才能真正实现碳固定。[1] 鉴于这些约束条件，分析建议打开窗户，表明室内植物策略在实际应用中并不可行。[1]
An analysis of employing indoor plants to mitigate carbon dioxide emissions reveals significant practical limitations despite theoretical feasibility [1]. Humans produce approximately one kilogram of CO₂ daily, which would require plants to convert through photosynthesis into oxygen [1]. While the theoretical minimum energy requirement stands at 132.5 watts under ideal conditions, accounting for actual plant efficiency raises this to 918 watts [1]. In real-world scenarios, however, achieving meaningful CO₂ reduction would demand between 5,000 and 10,000 watts of LED lighting [1].
The spatial and biological constraints further undermine the viability of this approach [1]. Removing CO₂ effectively would necessitate a minimum plant leaf surface area of 17.6 square meters, combined with the need to grow and remove 4.6 kilograms of new plant biomass daily to achieve genuine carbon sequestration [1]. Given that plants reach light saturation at approximately 52 watts per square meter, the energy costs and space requirements make this strategy impractical for indoor environments [1]. The analysis concludes that opening windows remains a far more efficient alternative to relying on houseplants for carbon dioxide reduction [1].
