Google’s 2025 Environmental Report provides a detailed look at its progress toward achieving net-zero emissions across operations and its value chain by 2030, while highlighting the growing environmental impact of artificial intelligence infrastructure.
In 2025, Google reported a 13 percent increase in total greenhouse gas emissions compared to the previous year, largely driven by the expansion of data centers and rising supply chain emissions linked to hardware manufacturing. The report underscores the dual role of AI, which offers significant decarbonization potential but also increases energy consumption due to compute-intensive workloads.
To address this challenge, Google is advancing its goal of operating on 100 percent 24/7 carbon-free energy across all grids by 2030. In 2025, the company achieved an average of 64 percent carbon-free energy usage globally, with several regions in Europe and the Americas exceeding 90 percent. Under the leadership of Chief Sustainability Officer Kate Brandt, Google is investing in advanced energy solutions such as geothermal power and long-duration energy storage to ensure reliable clean energy supply for AI infrastructure.
The company is also driving innovation in grid-scale clean technologies. Its enhanced geothermal systems project in Nevada represents a major step toward delivering continuous carbon-free power. In addition, Google is expanding investments in clean hydrogen and small modular nuclear reactors to diversify its energy mix. By leveraging AI to optimize these energy systems, the company aims to demonstrate that high-growth digital services can coexist with a decarbonized and stable power grid.
Water stewardship remains a critical focus area as cooling demands increase. Google has set a target to replenish 120 percent of the freshwater it consumes by 2030. In 2025, it restored approximately 18 percent of its freshwater usage through watershed projects. The company has also deployed AI-driven cooling systems that reduce data center cooling energy consumption by around 30 percent. Additionally, it is adopting water-conscious cooling technologies that use reclaimed or non-potable water, helping conserve freshwater in water-stressed regions.
Google is making steady progress in circular economy initiatives across both consumer hardware and data center operations. In 2025, 100 percent of newly launched Nest and Pixel devices incorporated recycled materials, with some components containing up to 50 percent recycled plastics. Within its data centers, 27 percent of components used for server upgrades were sourced from refurbished or diverted materials, supporting efforts to extend hardware lifecycles and reduce electronic waste.
Addressing supply chain emissions is a key pillar of Google’s net-zero strategy. In 2025, the company required suppliers representing 80 percent of its manufacturing spend to adopt science-based emissions reduction targets. Google is also providing financial and technical support to help suppliers transition to renewable energy, aiming to reduce the carbon intensity of producing semiconductors and servers essential for AI services.
Under the leadership of Sundar Pichai, Google is positioning AI as a tool for climate action. Initiatives include using machine learning to optimize global logistics and predict wildfire risks, helping industries lower their carbon footprints. Despite the current rise in emissions, the company remains committed to long-term decarbonization, focusing on scaling carbon removal technologies and strengthening supply chain engagement to align with global climate targets.
Overall, Google’s 2025 Environmental Report reflects the complex balance between rapid AI-driven growth and sustainability, with continued investments in clean energy, efficient infrastructure, and circular practices shaping its path toward net-zero emissions by 2030.
