Fossil Free Web 2026 (officially titled the State of the Fossil-Free Internet 2026) is an annual briefing and data project that monitors the internet’s transition toward renewable energy. It provides a status update on the 2030 goal of a fossil-free internet, focusing on the environmental impact of infrastructure expansion driven by artificial intelligence and hyperscale data centres. This resource is relevant to finance professionals seeking to understand the carbon intensity of the tech sector and the physical infrastructure risks associated with energy demand.

Organisation behind the tool

The tool is developed and maintained by the Green Web Foundation, an organisation focused on transitioning the internet to green energy by 2030. The report incorporates data visualizations and mapping provided by Christian Laesser and Data Center Map.

What the tool does

The tool provides a comprehensive analysis of the internet’s energy footprint through the following features:

• A global map of data centre locations, categorised by verified green energy use versus unverified status.
• Tracking of hyperscale data centre capacity and ownership, focusing on major operators like Amazon, Microsoft, and Google.
• Green Web Checks, a verification service that indicates if specific websites show evidence of being powered by renewable energy.
• Analysis of data centre energy demand trends, local grid impacts, and the correlation between generative AI growth and fossil fuel consumption.

Target audience

The primary audience includes technologists, climate researchers, sustainability officers, and policymakers. It also serves community activists and businesses looking to verify the environmental credentials of their web hosting providers.

Relevance to finance professionals

Finance professionals can utilise the tool for:

• Risk assessment – evaluating the regulatory and reputational risks of tech investments as data centre emissions rise and local energy grids face strain.
• ESG analysis – accessing empirical data on the carbon intensity of major tech companies and identifying gaps between corporate net-zero pledges and actual fossil fuel use.
• Market insights – monitoring the massive capital expenditure (estimated at $3.2 trillion) planned for global data centre infrastructure.
• Investment context – understanding the long-term sustainability of the AI boom and its reliance on fossil-fuelled power generation.
