This Week in Green Software, hosts Kate and Tzviya explore how green software is moving from theory to practice, highlighting new reference implementations for measuring Software Carbon Intensity in AI workloads and progress toward standardizing SCI for Web. They also examine the growing energy demands of AI and data centers, discuss the role of policy and awareness in driving change, and reflect on why practical tools and real-world examples are essential for turning sustainability goals into everyday engineering decisions.
