Sustainable Web Design

The Internet's Carbon Cost

If the internet were a country, it would be the 6th largest polluter. Every byte transferred requires energy—from the data center, through the transmission networks, to the user's device. Heavy, bloated websites aren't just slow; they are dirty.

As digital creators, we have a responsibility to minimize this impact. Sustainable web design is about efficiency, which happily aligns with performance and user experience.

Green Coding

We practice sustainable design by:

  • Optimizing Assets: Using modern formats like AVIF and WebP, and aggressive lazy loading to only load what is seen.
  • Dark Mode: Designing dark-default interfaces saves significant battery life on OLED screens, reducing charging frequency.
  • Efficient Caching: Reducing server requests through smart CDN caching strategies.

Good performance is good for the planet.
