Green transport revolution (5)
I believe the answer is:
cycle
This might be a double definition.
'green transport' is the first definition.
'cycle' can be an answer for 'transport' (cycle is a kind of transport). I am unsure of the 'green' bit.
'revolution' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for cycle that I've seen before include "Two-wheeler" , "Travel by pedal power" , "Wagnerian series?" , "Go by bike" , "Series of stories or poems" .)
