The European Framework Initiative for Energy and Environmental Efficiency in the ICT sector aims to promote green IT solutions that can significantly reduce greenhouse gas emissions from cities, which contribute to 70% of global emissions. The project supports various stakeholders, including public administrations and businesses, in becoming more energy-efficient and environmentally friendly through resources such as self-assessment tools, webinars, and a marketplace for sustainable ICT suppliers. Key cities like Malmö and Linköping demonstrate successful implementations of eco-friendly practices, reducing their carbon footprints through innovative ICT solutions.
