The green padlocks are only for EV certs. Let&#x27;s Encrypt doesn&#x27;t do EV certs (nobody automatically issues those). There&#x27;s a reason why browsers visually distinguish between EV certs and DV certs, and it&#x27;s because DV certs don&#x27;t indicate anything at all beyond the fact that the cert owner is able to serve HTTPS at a given domain.
