Lithuania’s advanced digital infrastructure and dynamic technology ecosystem provide excellent conditions for developing Green Software Engineering. The country has near-universal 5G coverage, an almost entirely fibre-based network, and a strong cybersecurity framework. The adoption of artificial intelligence among Lithuanian businesses is also progressing and is now slightly above the EU average. At the same time, the European Commission has identified the need for a more integrated green and digital strategy with measurable national targets. GREENByte research shows that students are eager to gain practical experience in clean coding, software optimisation, efficient data processing, and software energy measurement. Academics are ready to integrate sustainability into their teaching but require structured educational resources, practical exercises, and assessment tools. Industry increasingly understands sustainable software development as an important component of software quality, operational efficiency, cybersecurity, and long-term competitiveness. GREENByte can help connect Lithuania’s strong digital capabilities with more systematic Green Software education and practice.
