<p>The lifecycle of a computer application (expressing needs, specifications, cycle development / qualification, production, end use) is marked by decisions impacting significantly its overall environmental footprint.<br />
Upstream of the development phase, is the choice of a programming language one of those decisions? In particular, has this choice a quantifiable impact on a software energy consumption?<br />
We shall answer this last question in the limited context of a case study.</p>
A consortium of companies grouping KaliTerre, TOCEA, the engineering school of ICAM Nantes and SIGMA Informatique have launched the project "Code Vert" which aims to develop software that will verify the "Sustainability" of a software. This tool uses a repository of best practices for software design more friendly environmental from its establishment phase until its waste phase. This project, accompanied by Atlanpole, has been accredited by the competiveness cluster "Image & Réseau" in December 2011 and started its operational phase in February 2012.
