|Sustainability Plan / Air Quality / Indicators|
|Number of existing buildings that join the Building Air Quality Alliance Program (or similar voluntary programs).||
|Number of people going to clinics for respiratory problems.||
|Percentage of new cars registered in San Francisco which are alternatively fueled (e.g., California Air Resources Board-certified, low emission vehicles, ultra-low emission vehicles, or electric vehicles).||
|An upward-pointing arrow indicates that the measurement should rise
if the City is moving in the right direction; a downward-pointing arrow indicates
that the measurement should fall.
These indicators, sampled on a regular basis, will give a birdís-eye view of whether San Francisco is moving toward or away from a sustainable future. Of course, none of the topics are completely covered by the few listed indicators, and there are certainly infinitely more things that could be tracked. These ongoing measures are meant to give an overall indication of whether the City is moving in the right direction, and provide a way of measuring significant trends without entailing major new expense for data-collection. Baselines for these indicators have yet to be researched.
