The tech industry is increasingly focused on adopting sustainable practices. In this article we look at ways to build greener websites and applications.

Why it matters

From reducing server energy consumption to optimizing frontend performance, there are many ways developers can contribute to a greener future:

1. Efficient assets — Optimize images, use modern formats, and lazy-load.
2. Less JavaScript — Ship only what you need; code-split and tree-shake.
3. Green hosting — Prefer providers that use renewable energy.

Small steps

You don’t have to rewrite everything. Start with:

• Enabling compression (gzip/brotli)
• Setting cache headers
• Measuring with Lighthouse and Core Web Vitals

Every improvement helps. Sustainable web development is about doing better with less.
