Streets was not intended for use outside of the United States of America because the software uses tree growth, climate and cost data based on reference cities in 16 different climate zones throughout the United States.
In order to calculate tree-related benefits for your city, for instance, Streets must know what species are most likely to be found in your region, how big the trees are expected to grow, how quickly they will reach mature size and what leaf area they will have. The application also uses building, energy use, land use, and climate information to calculate trees’ functionality. Unfortunately Streets doesn’t have these data for cities outside of the U.S. As a result, any analysis you conducted using Streets would lack regional field data to support it.
While there is no facility for calculating error associated with trees outside the specified climate zones, a first order approximation of benefits and resource is possible. It’s up to you whether or not the results will be valid for their intended use.

A journal article by Greg McPherson, Selecting Reference Cities for i-Tree Streets, is also available describing a systematic process for selecting the best reference city for international applications if you are considering the Streets model abroad. https://www.itreetools.org/streets/reso ... %20AUF.pdf
