i-Tree Eco International
i-Tree Eco has different requirements and provides different results depending on whether your project is in the US, in selected international partner countries (Canada, Australia, the United Kingdom, Mexico, South Korea, Colombia & Europe), or in other countries where the model can be used in individual cities.
For the US, the i-Tree Eco model comes preloaded with local weather and pollution data from a network of monitoring stations. The software also includes local species, climate, and human population data for US locations. All of this preloaded data means US users only need to select their location and provide their tree measurements before submitting their data for automated processing and same-day results retrieval.
Canada, Australia, the UK, Mexico,South Korea, Colombia & Europe: i-Tree Eco Ready
The i-Tree Eco software now operates in multiple partner countries the same way it operates for users within the US where available data permits. After establishing a cooperative development agreement with the i-Tree Team, international partners worked directly with the US Forest Service and the i-Tree Development Team to adapt the model and provide required data for automated same-day project processing.
Though Eco is fully functional in these partner countries, there are still a few limitations to consider.
- The energy effect model is adapted from US research that reflects US building practices, climate types, energy uses and emissions factors, which may limit the applicability and accuracy outside the US. For some countries, energy estimates may be enabled based on matching an international location to a US climate region. The following spreadsheets show European/US climate region assignments and regional characteristics (building vintage, percentages, fuel types, etc.) of US climate regions.
- The human health impacts of air pollution removal are based on a US specific model created by the Environmental Protection Agency and are not available for international projects.
- The available pollution and weather year for adapted partner country projects is limited to the year of pollution data that was provided by partner countries for integration in the Eco model.
- For partner country specific model integration details, see the Air Pollutant Removals, Biogenic Emissions and Hydrologic Estimates for i-Tree Applications documentation.
i-Tree Database for Other Countries
i-Tree Eco v6 can be used in all other countries, outside of partner countries mentioned above, but it requires use of the new i-Tree Database system. This online portal was developed to accommodate growing international interest in Eco and provides a automated process for users to submit new international city location information, hourly pollution data, and hourly precipitation data to be validated and later incorporated in future version of Eco.
Many international users have used this process and numerous global cities are now available for all to use in Eco. See the list of Other International Cities to view which cites and data are available in Eco. Some global cities may only have a location and limited pollution or precipitation data, which will limit some Eco reports availability for an individual city.
Visit the i-Tree Database page and select "Get Started" to learn more. Spreadsheet templates for pollution and precipitation hourly data submission can be found under the i-Tree Database Resources section of the i-Tree Methods and Files Page. and the "Add to Database" menu options for pollution and precipitation.

Additional International Eco Resources
The following resources are to help users outside the United States who are considering or are in the process of conducting i-Tree Eco projects. Please also visit the Resources-Archives section of the website for additional Eco resources
Eco Guide to International Projects - Former guide for international projects outside the U.S, AU, CAN and the UK. This guide can be used for reference while it is being updated for the new i-Tree Database system.
The Australia and Canada features have been fully integrated since 2012 leading to dozens of projects in those countries. In Australia, ENSPEC coordinated efforts with the i-Tree Eco Development Team to collect species, location, environmental and economic data with additional support and funding form the Melbourne Urban Forests Accord Group and Arboriculture Australia. Andy Kenney (University of Toronto) helped facilitate data acquisition for development of the Canadian Eco localization.
