Carbon you can actually compute.
Every page in this site reports its own carbon footprint in the footer pill. The number is computed locally from transferred bytes × regional grid intensity, with no third-party tracking. The methodology is published below.
Sustainable Web Design Model v4 baseline.
The footer pill multiplies transferred bytes by a published kWh-per-GB coefficient and the visitor's nearest grid's gCO2/kWh figure. No estimation of device-side energy or upstream embodied carbon — those land in a v2 of this disclosure.

Region detection
Visitor timezone → nearest FlyttGo region. No IP geolocation, no third-party API.
- M.02
Bytes transferred
performance.getEntriesByType('resource') sum + navigation entry. Cached resources contribute zero.
- M.03
Energy coefficient
Sustainable Web Design Model v4: 0.81 kWh per GB transferred end-to-end.
- M.04
Grid intensity
Per-region gCO2/kWh from IEA 2024 + national grid operator publications.
Per-region grid carbon intensity registry.
| Region | Label | gCO2 / kWh | Note |
|---|---|---|---|
| EU-N | Nordic EU | 25 | Hydro-dominant grid, near zero-carbon |
| EU-W | Western Europe | 230 | EU mainland mix |
| NA-W | North America · West | 240 | CA hydro + solar mix |
| NA-E | North America · East | 380 | Mixed gas + nuclear |
| SA | South America | 90 | Brazil hydro-heavy |
| AF | Africa | 470 | Heavily fossil; offset programmes available |
| MENA | Middle East · GCC | 540 | Fossil-heavy; sovereign deployments only |
| APAC | Asia-Pacific | 410 | Mixed; coal share decreasing year-on-year |
| OCE | Oceania | 510 | Coal-heavy; renewable transition under way |

Engineered to choose the lowest-carbon path.

Region-aware routing
Customer-cloud deployments default to the lowest-carbon eligible region unless a data-residency policy overrides. EU-N (25 g) is selected by default for any deployment without a regional constraint.
- PC.02
Edge-cached HTML
Marketing pages cached at the edge with stale-while-revalidate so visitor requests rarely round-trip back to origin. Cache headers in middleware.ts; per-locale cache keys via Vary.
- PC.03
Static-first delivery
Workspace data is rendered server-side; marketing surface is fully static where possible. View Transitions + Speculation Rules cut perceived navigation latency without extra round-trips.
