Seventy five percent of New York City's greenhouse gas emissions come from the energy used by buildings. Reducing this energy is a goal of both building managers and the City of New York.
This visualisation takes data about the carbon emissions of municipal buildings in New York City and transforms it into a 3D map of the actual volume of carbon dioxide added to the atmosphere. The city and its buildings are an essential component of the data visualisation.

This form of visualisation also lends itself to a form of data analysis that maintains a physical sense of scale. In this view the distribution of emissions is evident for buildings of different ages. If there were an age-based trend this may give the first view of it. The visualisation does show problems with some records that would not be easy to spot in the table (the block of volumes at the back).
