The open Peer Networking Meetups that began when Covid-19 struck and we were all suddenly working from home have proven their value. In consultation with those who were on the last few calls we’ve decided to make them a permanent, monthly event.

Discarded tires are an environmental disaster, and finding a beneficial use for them is a high priority.

BuildingGreen does not approve any flooring product that is made with tire-derived rubber, though some products may be appropriate for exterior use.

If I'm remembering correctly, someone at the summer summit mentioned working on / or being familiar with the Berkeley CA gas ban. A town here in MA is also considering a ban and wanted to get some feedback from Berkeley.
