On Monday the largest day-to-day change was at Bellbird Park, where the daily average fell by 18ppm – about the same amount by which it rose three days earlier. 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.
