Combining news of the UK government’s commitments to cut carbon emissions by 78% by 2035, with the search volume of “house plants” and related phrases on google increasing by 114%, has used research data to provide an expert study on the number of houseplants needed to offset the CO2 emissions of your household appliances and the results are kind of a big dill…

Our results show that on average, a houseplant will absorb 0.0647875 CO2 emissions (kg) per year. This means, in total, you would need an average of 12,626 houseplants to offset the emissions of just 10 household appliances. 

Emitting around 159 kg of CO2 emissions per year, the electric tumble dryer uses the most energy and requires a total of 2454 houseplants to offset its CO2 emissions. However, gas ovens emit the least amount of energy, requiring only 587 houseplants to offset its CO2 emissions for the year.

The Prayer plant is the most energy-efficient household plant to buy, absorbing around 0.0977105 of CO2 (kg) in 1 year.
