Foreword Digital technologies have transformed the way we live and work, creating new opportunities, driving economic growth, and helping us tackle some of the planet’s most pressing challenges. As digital infrastructure expands, accelerated by the rise of AI, responsible stewardship of ecosystems and natural resources like water, land, minerals and energy will be essential. This creates both a responsibility and an opportunity for the tech sector to show that innovation can advance while protecting the natural systems we all rely on. Across the tech sector, companies are innovating to accelerate a nature-positive future, helping industries manage water with precision, monitor ecosystems and conservation efforts, scale circular markets for critical minerals and direct investment towards measurable environmental outcomes. These efforts show what is possible when technology and sustainability move forward together. At Microsoft, we believe those who can do more, should. That is why we’ve woven sustainability into how we design, build and operate the physical infrastructure that supports our cloud business and AI. When nature is overlooked, the consequences ripple across communities and economies. Taking steps to use resources responsibly helps to reduce those impacts, lower costs and drive innovation for sustainable operations and energy. The priority actions in this report help to turn that responsibility into practical steps across site selection, operations, procurement and product design that protect natural resources while creating business value. At Microsoft, we have seen this firsthand. In Mount Pleasant, Wisconsin, USA our AI data centre is expected to set a new benchmark for sustainable design, by using a closed-loop cooling system that allows more than 90% of the facility to recirculate water continuously. We plan to balance our energy use by matching fossil-fuel consumption with carbon-free energy on the grid, including power from a nearby solar project that’s now under construction. We are also conscious of our impact beyond our immediate footprint. This is why we are partnering with local organizations to restore important prairie and wetland habitats. Achieving impact at scale will require collaboration between companies, governments, investors and communities. We need to plan together, invest together and innovate together. The challenges ahead are substantial, but we remain optimistic. If we work collectively, technology can help us not only grow and innovate but restore and protect the planet for generations to come.Melanie Nakagawa Corporate Vice President & Chief Sustainability Officer, Microsoft Nature Positive: Role of the Technology Sector December 2025 Nature Positive: Role of the Technology Sector 3
