To see an example of of well-established hybrid university/community CO2 monitoring network elsewhere – and there are not many – do visit the San Francisco Bay Area’s Beaco2n project run from UC Berkeley. We’re growing the network – if you’d like to host or sponsor a sensor – leave us a message. As we add more sensor sites, comparisons across the urban area will become more robust and informative about Brisbane’s Carbon dioxide emissions.
