This edition collectively explores the critical intersection of artificial intelligence, digital infrastructure, and environmental sustainability as the industry moves towards 2026. Experts highlight that while AI offers transformative potential for climate mitigation, its rapid expansion creates significant energy and water demands that necessitate smarter, more efficient hardware and software design. Key strategies discussed include liquid cooling, waste heat recovery, and circular hardware cycles to reduce the carbon footprint of expanding data centres. Regional perspectives from Europe and the Nordics emphasise that green technology is shifting from a voluntary ESG initiative to a core economic and security strategy. Furthermore, the texts showcase practical innovations such as Green Prompt Engineering and renewable energy integration as essential tools for achieving net-zero goals. Ultimately, the contributors argue that the future of technology depends on a systemic transition where ecological responsibility is embedded into every layer of digital innovation.These sources collectively explore the critical intersection of artificial intelligence, digital infrastructure, and environmental sustainability as the industry moves towards 2026.
