Every byte has a cost. The most sustainable sites are not just fast, they are intentionally small. They respect the user's device and the planet's energy budget.
Start with transfer size. Shrinking images and deferring scripts often yields the biggest carbon savings with the least effort.

Static delivery and aggressive caching reduce repeat computation. The fewer times we ask a server to render the same content, the less energy we burn. Shipping the right asset, in the right format, matters more than fancy effects.
Speed is the visible benefit. Efficiency is the invisible one.
"A performance budget is also a carbon budget."
SUSTAINABLE_RUNTIME
Green computing in the browser is about restraint. Fewer scripts, smaller images, and shorter waterfalls add up to a meaningful reduction in energy use.
- Ship images in modern formats and size to the container.
- Defer non-critical scripts and avoid autoplay media.
- Use caching headers to prevent repeat downloads.
Sustainability is a design choice. When we choose simplicity, we also choose longevity.
