Somehow funny that this needs to be marketed as a climate project. That impact is probably marginal, and energy/material cost of the surface material - not covered here - is more important. Probably it has more positive effect by reducing flooding, which tends to get worse in built up areas with lots of pavement. When rain and melting snow can bw absorbed to the ground, flooding risks go down.
