This is a personal website, not a company with a certified report. This page
documents the environmental choices behind it — and their limits.

## Hosting and delivery

The site is pre-built as static files and served by nginx: no per-visit
rendering, no database query behind a page view. Hosting is OVH, with Cloudflare
caching in front, so repeat visits are served from cache rather than the origin.
The machine-readable version of this statement lives at /carbon.txt.

## Lightweight by design

Assets are pre-compressed at publish time and cached immutably, so repeat visits
transfer almost nothing new. Fonts are self-hosted, icons are inline SVG, and
images are resized at build time. There is no advertising, no third-party
tracking, no auto-playing media. Search runs on a pre-built local index, and the
search code loads only when first used.

## Analytics

When enabled, analytics is self-hosted Matomo — no data is sold or shared with
ad networks. See the privacy page for details.

## Supply chain

Beyond OVH (hosting) and Cloudflare (CDN), this site has no other runtime
infrastructure provider. Both publish their own environmental data:

- [OVHcloud environmental data — efficiency indicators, carbon balance, and sustainability statement](https://corporate.ovhcloud.com/en/sustainability/environment/)
- [Cloudflare Impact — annual emissions inventories and Impact Report](https://www.cloudflare.com/impact/)

## Limits

Static does not mean zero-carbon: networks, devices, and datacenters still
consume energy, and the visitor’s device dominates the footprint of a page view.
The statements above describe the architecture, not measured grams of CO₂.
