Council tree felling...

[Cyclone]

Are you saying that you aren't defending them?

Since the replacement trees are smaller species than ones being replaced, the long-term net effect is greater CO2 emissions.

Greater CO2 emissions from what?

Suppose the mature tree being cut down weighs 100 tons, and its replacement, when fully grown. weighs 50 tons. Then in the long term replacing the tree with a smaller species will have released the carbon content of 50 tons of wood more than if the original tree  had been left.

Lower CO2 absorption and lower O2 emission would be more accurate.

Also that.  But trees absorb CO2 and produce O2 even when not actively getting larger.

What happens when the 100T tree dies and the replacement tree never existed?

That's still a terrible argument for removing mature trees for no good reason.

When the 100T tree dies, I would hope that the council will plant a sapling that will in time grow to 100T

In isolation the argument would be yes.

 

But in terms of the overall impact of replacing ornamental trees on inner city streets it should be considered.

You are making that argument in isolation in an attempt to justify the tree felling that took place in order to make the contract cheaper for Amey.
