Does Bamboo Produce Oxygen? The Plant's Climate Role Explained
Short answer: Yes, bamboo produces oxygen, as all green plants do through photosynthesis. Because bamboo grows fast and has dense foliage, a bamboo plantation can produce a lot of oxygen per area while absorbing a lot of CO2. The figures do vary with species, climate and cultivation.
Photosynthesis in brief
In photosynthesis, the plant uses energy from sunlight to turn CO2 from the air and water from the soil into sugar. The sugar is used to build new leaves, stems and roots, and oxygen is released as a by-product. The process is basically the same in all green plants.
Fast growth means a lot of work
Bamboo is known for growing unusually fast during the growing season. When a plant is constantly building new mass, photosynthesis runs at full speed and a corresponding amount of oxygen is released. A slow-growing plant also makes oxygen, but at a calmer pace and over a longer time.
The leaves do the work
It is mainly the leaves that carry out photosynthesis. Bamboo has many narrow leaves along the stem, and in a dense stand they catch much of the light that falls through. The more light the plant uses, the more sugar it makes, and the more oxygen is released.
More oxygen than forest
Some comparisons suggest that bamboo plantations can produce more oxygen per area than many tree plantations, because growth is faster and the plant regrows after harvest. The figures vary with species, soil and climate, though, so take specific percentages with a pinch of salt.
Oxygen and CO2 go together
When the plant makes oxygen, it takes up CO2 from the air at the same time. The carbon is stored in stems, leaves and the large root system underground. When a stem is harvested, the roots stay in the soil and send up new shoots, so the ground is not left bare.
What the oxygen means in practice
The oxygen in the atmosphere comes from plants and algae all over the planet, and a single plantation does not change the air you breathe. Oxygen production is mostly a sign of how actively the plant grows. That speaks well for the raw material, but it is not an argument for a garment on its own.
From plant to fabric
The plant is a good starting point, but processing counts too. Bamboo cannot be spun directly, so the cellulose is dissolved chemically and spun into bamboo viscose. That process uses energy and chemicals, and what happens in the factory matters just as much as what happens on the plantation.
Look for certification
If you want to know more about how the raw material is grown, you can look for certification. See FSC for the products whose raw material comes from operations that follow a forest standard. Read what the certificate covers, because it concerns the plantation and not how the fibre is made.
Wear your clothes for a long time
The thing you can influence most is how often you wear your clothes. A garment used for years spreads its production over many days. Wash at 30 to 40 degrees, skip fabric softener and the tumble dryer, and let the garment air dry so the fibres keep their shape longer.
Our range
See bamboo clothing for women and bamboo clothing for men, where the material composition is listed on every product. You will find basics, underwear and nightwear for everyday use. Check the care label when you choose, so you know how the garment should be looked after. See also the honest guide to bamboo and the environment.
Frequently asked questions
Does bamboo produce more oxygen than trees?
Per area, a bamboo plantation can produce a lot of oxygen because it grows fast. The figures depend on species, soil and climate, so comparisons should be read with caution.
Is bamboo clothing good for the climate because the plant makes oxygen?
Not automatically. The growth of the plant is a good starting point, but processing into fabric and how long the garment is worn matter at least as much.
What does FSC mean on bamboo clothing?
FSC says something about how the forest or plantation is managed. It does not necessarily cover how the fibre is made afterwards, so read what the certificate includes.
