How this page is made, what it weighs, and what it costs to send to you. We publish this because a website’s environmental cost is usually invisible, and because a festival arguing for slower, less extractive cultural practice should be able to account for its own.

How it is built

One HTML document. No framework, no build step, no content management system.
No cookies of our own, no analytics and no tracking scripts. The one third-party element is the newsletter sign-up, an embed from Substack that loads as you scroll to it; Substack’s own privacy policy applies to anything you enter there.
One line of JavaScript, which sets the header photograph. The page works without it.
The decorative shapes and rules are drawn as vector paths written into the stylesheet, so they cost no extra requests and no image data.
The photograph is embedded in the document rather than loaded separately. That removes a request but adds about a third to the image’s size, because of how binary data is encoded as text.

What it weighs

Photograph	152 KB
Funders’ logos	18 KB
Text, layout and script	11 KB
Whole page	237 KB

Typefaces are requested separately from Google Fonts and are not counted above. Removing the photograph would cut the page by roughly two thirds.

What that costs

0.03 g CO₂e and 0.07 Wh per visit

Calculated with version 4 of the Sustainable Web Design Model, which puts the operational and embodied energy of moving data at 0.300 kWh per gigabyte across data centres, networks and user devices, and uses a global average grid intensity of 494 g CO₂e per kWh from Ember’s world dataset. 237 KB at those rates gives the figures above. The model is an estimate of a system-wide average, not a measurement of your visit: the real figure depends on the electricity where the page is served, the network it crosses and the device you are reading on.

An independent test by Website Carbon on 9 October 2026 gave the same result: 0.03 g of CO₂ per visit, a rating of A+, cleaner than 95% of web pages tested globally.

For comparison and method, see Website Carbon and the Green Web Foundation’s CO2.js, which implements the same model.
