Anarchic contra not pro FBI's measure of green policy (6,9)
I believe the answer is:
carbon footprint
'measure of green policy' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'anarchic contra not pro fbi's' is the wordplay.
'anarchic' indicates anagramming the letters.
'contra'+'not'+'pro'+'fbi'='contranotprofbi'
'contranotprofbi' with letters rearranged gives 'CARBON FOOTPRINT'.
Can you help me to learn more?
(Other definitions for carbon footprint that I've seen before include "From measure of energy usage" , "personal effects?" , "emission level" , "emissions" .)
