Re: Next steps towards a net zero IETF

Greetings!

Earlier in the thread, there was a request to hear from remote participants. I remained remote for this meeting as the distance to travel added too much away time in total. I am planning to be in San Francisco. 

In the past, I did stay up all hours to attend meetings. This was because of a direct responsibility as an AD at the time. For this meeting, I attended all sessions where I was a chair or presenting. I had co-chairs in the room or this would not have been possible. 

The presentation went well with me remote (my perception), but I did have someone in the room in case that helped.

I’m going to watch the recordings of meetings that happened in the very late hours and of course something is missed. 

I do think we can achieve more remotely, but we need to work together for that to be possible.

Michael’s suggestion for plenary meetings makes sense. I also appreciate WGs that meet frequently in between meetings as that lessens the need for travel too. The only problem with that (for me) is that I have a standing conflict with one of them and gave to decide each week what to attend.

I do think we can do better. We have to be willing.

Best regards,
Kathleen
