The Green-IT Initiative in Amsterdam aims to reduce CO2 emissions in the city by 40% by 2025 by making the ICT sector and data centers more energy efficient, and by using ICT to enable efficiency in other sectors. Over 25 organizations in Amsterdam have joined the initiative to share best practices, set benchmarks and goals, and develop pilots to reduce energy usage. The initiative seeks to promote collaboration across industries to design more efficient data centers, equipment, and applications to cut emissions from ICT and enable other sectors to reduce their carbon footprint through digital technologies.
