Q.How Much Carbon Does A Phormium Plant Take In Compared To A Tree ,because If It Took In As Much Then It Be Advantageous To Grow Th
em as they are not as flammable as trees because they don’t drop their leaves to form a tinder box below their canopy so less ca rbon would be produced by these gigantic forest fires.

Generally, plants are more effective at reducing the, already very low, CO2 levels in the air than trees will be. Trees tend to contribute more carbon dioxide at the end of their lives than they take in.
Now, on to CO2 levels. Generally, we never sit above 400 ppm. Plants prefer it around 800 to 1000ppm We would have to double our CO2 production in order to give plants what they would need, but they would produce O2 just as fast as they consumed CO2. In fact, this is common for indoor gardens. Ramp up CO2 so that plants will go through their processes faster. Anything that you add will be taken up within an hour.
It is important to remember that CO2 is heavy compared to other gases. It will sit close to the surface, so when we supplement, it is from above. It will trickle down and settle around the plants, close to the ground.
Where we DO run into issue, is with Carbon MONOXIDE. This gas is detrimental to all living organisms, and will be the main reason for air pollution when burned. It will take the place of CO2 and O2, causing damage in both plants and animals.
With all of that said, A fast growing and herbaceous plant will be the best option for air contamination removal. Because they have a low carbon footprint, they cannot contribute much carbon, in any form.
Keep in mind that depleting the area of natural carbon, in both solid and gas form, can have equally as negative of a consequence. Some of this detritus needs to go back into the soil in the form of carbon rich nutrients for plants and soil microbes.
In short, your best option would be Phormium, over any trees.
