绿步骤跟踪您的旅行，并揭示其环境影响
Green steps tracks your travels and reveals their environmental impact. The app evaluates the mean of transport, the length of your path and the route you choose.
At the end of your travel, Green Steps scores it: you get 100 points for a perfectly green travel, zero for a very polluting one. You can also share your scores with social networks or email.
To improve usability in next updates, Greens’ employs Google Analytics to anonymously collect use statistics.
The initiative
Greens’ is a prototyping and demonstration phase of "TETRA Innovative Open Source Services", a project of PON Ricerca e Competitività 2007–2013 centred on smart cities and smart objects.
TETRA Innovative Open Source Services is a multilevel initiative, that deals mostly with emergency operations, environmental defence, sustainable mobility and tools that aim to improve everyday life in urban areas.
