Why am I unable to appoint my verifier in the EU ETS Registry? And can I appoint another verfier?

If you are unable to appoint your verifier, it is most likely that they do not yet have a verifier account in the registry. You have to appoint the same verifier as the one you use for the MRV obligations. So you cannot select another verifier for the ETS obligations. Please note that we are working hard to add all the verifiers to registry a.s.a.p. and your verifier should be available soon.
