Leave carbon recycling to tip (11)
I believe the answer is:
overbalance
'tip' is the definition.
(I've seen this before)
'leave carbon recycling' is the wordplay.
'recycling' is an anagram indicator.
'leave'+'carbon'='leavecarbon'
'leavecarbon' with letters rearranged gives 'OVERBALANCE'.
'to' is the link.
(Other definitions for overbalance that I've seen before include "Topple" , ""take a tumble."" , "Come a cropper" , "Capsize" , "Fall down" .)
