CITYgreen is a Geographic Information System (GIS) software program for mapping, measuring and analysing a number of different characteristics associated with green infrastructure in urban areas. These include storm water dynamics, summer energy savings, carbon storage and sequestration, air quality, and wildlife. The program enables the user to carry out complex analysis of the economic benefits of urban ecosystem services and to create clear, easy-to-understand reports that can be used for presentation in the planning process. The software can help communities determine what amount and type of green infrastructure is needed to meet sustainability objectives. For example, it can be used to calculate the annual quantity of pollutants removed by urban trees and its associated economic value.


CITYgreen is as an extension for ArcGIS software and requires the user to supply landcover data in the form of aerial photography or satellite imagery. The software is provided by American Forests.
