How We Track Carbon Data in Virtual Worlds

When we started Carbon Worlds Journal, we faced a real problem: there’s no standard way to measure carbon impact in virtual spaces. Second Life and other persistent online worlds consume electricity continuously, but attributing that consumption to individual users or activities requires assumptions. We built our methodology around transparency about those assumptions.

Our approach combines three data streams. First, we use published energy consumption figures from grid operators and hosting providers where available. Linden Lab, which runs Second Life, doesn’t release detailed server power data, so we work from industry benchmarks for data center efficiency and cross-reference against their stated infrastructure scale. Second, we pull real-world carbon intensity data from regional grid operators to convert kilowatt-hours into CO2 equivalent. This matters: a virtual world hosted in Iceland has a vastly different footprint than one in coal-dependent regions.

Third, we conduct our own user behavior surveys and in-world observation. We’ve documented how avatar density affects server load, how different content types (scripted objects, physics simulations, streaming media) change power draw, and how peak usage hours concentrate carbon impact. This data feeds our calculation framework, which we update quarterly as we refine our models.

We publish our raw assumptions, calculation spreadsheets, and margin-of-error estimates with every piece of carbon research. You’ll find these linked in our methodology notes on each article. We’re not trying to present false precision. The real value is consistency and traceable logic, so other researchers can either validate our work or modify it for their own context.

Our editorial standard: if we can’t source or calculate something with reasonable confidence, we say so. We’ve killed several story angles because the underlying data didn’t hold up. That’s the only way this work stays credible.
