— Digital sustainability report

A lighter web, by intention.

The internet has a measurable environmental footprint. This document outlines the principles, decisions and limitations behind the Planetiers World Gathering website — and what we are still working to improve.

— 01 / Context

Why digital sustainability matters.

The information and communications technology sector is estimated to account for roughly 2 to 4 percent of global greenhouse gas emissions — comparable to the aviation industry — and its share is growing.

Websites contribute to that footprint through the energy required to manufacture devices, run data centers, transmit data across networks and render pages on user hardware. Heavier pages, more requests and longer sessions all compound the impact.

A gathering dedicated to regeneration cannot ignore the medium through which it is announced. The digital experience is part of the message.

— 01.5 / Alignment

Why this matters for Planetiers.

A gathering focused on regeneration cannot ignore the footprint of its own digital infrastructure.

The website is part of the event experience, and therefore part of its responsibility.

Every page, image, interaction and request contributes to the overall impact of the gathering. Designing lighter systems is one small but meaningful way to align the medium with the message.

— 02 / Principles

Six principles that guide every decision.

These are commitments, not certifications. They are tested against every page, component and dependency we add.

Restraint by default

Every byte shipped is a deliberate choice. We prefer omission over decoration and ship only what serves the reader.

Performance is sustainability

Fewer bytes, fewer requests and less compute mean less energy consumed end-to-end — from data center to device.

Longevity over novelty

We design for years, not seasons. Stable patterns, durable typography and content that ages without breaking.

Accessibility is non-negotiable

An inclusive experience is also a lighter experience. Semantic structure, sufficient contrast, predictable motion.

Transparency over claims

We publish what we measure and what we do not. No certifications we have not earned. No metrics we cannot verify.

Renewable infrastructure

Hosting and delivery are selected for proximity to renewable energy grids and efficient edge computing.

— 03 / Practice

Decisions applied to this website.

A non-exhaustive list of the engineering and design choices behind the experience you are currently using.

01Media: Images served in modern formats (AVIF, WebP) with responsive sizing and lazy loading. Video is avoided unless it carries irreplaceable information.
02Typography: A limited type system with subset webfonts and system fallbacks. No decorative weights loaded unless used.
03Motion: Animation is reserved for orientation and meaning, not ornament. Respect for prefers-reduced-motion is built in.
04Color & contrast: A dark palette tuned in OKLCH to reduce screen luminance on OLED devices while maintaining WCAG AA contrast.
05Code & dependencies: A conservative dependency tree, server-rendered routes and code-split bundles to minimize JavaScript on first paint.
06Data & tracking: No third-party advertising trackers. Analytics are limited to what we genuinely use, with privacy preserved by default.

— 03.5 / Note

Digital systems are part of the solution.

Digital sustainability alone will not solve the climate crisis.

But responsible digital systems can reduce waste, improve accessibility and support more resilient forms of collaboration.

For a gathering focused on regeneration, these principles are not separate from the mission. They are part of it.

— 04 / Measurement

Measured impact. Verified performance, openly disclosed.

Sustainability should be measurable, not assumed. The Planetiers World Gathering website is regularly tested using independent performance, accessibility and carbon measurement tools. The results below reflect the current verified performance of the platform.
