Supporting environmental targets subject to law about pollution (11)
I believe the answer is:
sustainable
'supporting' is the definition.
Both the answer and definition are adjectives.
Perhaps they are linked in a way I don't understand?
'environmental targets subject to law about pollution' is the wordplay.
I cannot really understand how this works, but
'subject' could be 'ai' (AI is an example) and 'ai' is present in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sustainable that I've seen before include "It's a bus lane (anag.)" , "Maintaining a balance by not depleting natural resources" , "Able to be maintained" , "Able to continue over a period of time" , "Able to be kept going" .)
