I believe the answer is:

tesla

I'm a little stuck... Click here to teach me more about this clue!

'electric vehicle' is the definition.

'least pollution' is the wordplay.
'least' anagrams to 'TESLA'.
But, I am not clear how the anagram is indicated.

'makes' acts as a link.

Can you help me to learn more?
