How this result is calculated
Carbon is an estimate based on transferred response bodies, using Sustainable Web Design Model v4. Hosting energy is unverified; the standard grid assumption is used. Response headers are reported separately in the JSON.
This is a bounded observation of one page, with no consent interaction. Unfinished downloads and content beyond the scroll limit may be excluded. It is not a whole-website footprint or a measurement of electricity consumption.
Small pages. Meaningful information.
Page weight is one useful signal. Results include the measurement conditions and limitations, so you can understand what was captured and compare future scans responsibly.
