Trees as a weapon against climate change
The importance of CO₂ storage
Trees can help fight climate change. As they grow, their wood fibres lock in CO₂ through photosynthesis. "This captures some of the CO₂ gases present in the air for a long time," Professor Joris Van Acker of Ghent University says.
The CO₂ stays in the wood, even when it is processed into a new product such as flooring or furniture. "And even if we recycle and reuse the wood, the CO₂ stays locked inside the wood. Wood is therefore a good material to control climate change. Even when the end product can no longer be recycled, we can convert the energy that is stored inside the wood into green energy," the professor adds. This makes wood a much more sustainable material than alternatives such as concrete or metals.
