The Public Administration is forced to transform itself by taking advantage of the contribution of ICT to in the process of reducing bureaucracy and increase transparency, promoting the dematerialization of processes, increasing the quality of online services, allowing greater ubiquity of access, reducing response times, in the search for improvement of the quality of life of its citizens. Decision-making should consider objectives not only technical but also financial, environmental, and social objectives, ideally aligning with Green IT. The objective of the paper is to present a framework, supported by international standards and frameworks, that allows measuring and guiding the alignment of ICT with Green IT for the optimization of practices instituted in organizations, namely in Local Government. This framework includes a qualitative component with several phases and quantitative component with a metric that allows the evaluation of alternative strategies for a given goal. The phases considered are Problem Identification; Problem assessment; Study and planning; Project; Telecommunications and Printing; Information Security; Innovation; Improvement of Citizen Service; Evaluation / opinion. The complete metric includes four valences: IT, financial, environmental, and social. The IT valence, its indicators and corresponding weights are illustrated in a practical example. The proposed framework is an innovative contribution to the area, clearly integrating the support of the perspective of Green IT and thus actively contributing to the implementation of sustainability policies and alignment with Green IT best practices in Local Government, as well as presenting with greater level of detail the components of the structure that emphasize Green IT concerns. The main expected results of the application of the framework are contributing to the implementation, in local government, of sustainable policies and good practices aligned with Green IT, whist targeting cost reduction and optimization, ubiquity of access, increased productivity and ensuring safety standards.
