What makes a web page “low-carbon” in 2025 — and why it matters for planet-positive brands

Hi there!

I’m Uta –
Brand Strategist for planet-positive businesses and Founder of Carrot and Karma.

Introduction

Digital presence is now essential for almost every business. At the same time, there is growing awareness of the environmental footprint of the web, prompting many founders to explore more responsible digital design practices.

For planet-positive brands, a website isn’t only a visual asset — it’s a reflection of values, care and intention. As conversations around digital sustainability evolve, so does the question: what does a more responsible website look like in 2025?

Understanding the 0.35g CO₂ benchmark

Industry groups in digital sustainability — including the Eco-Friendly Web Alliance (EFWA) — have introduced guidance to help businesses understand and assess the emissions associated with web pages.

One referenced benchmark is a recommended threshold of ≤0.35g CO₂ per page view, used as an indicator to support more energy-efficient web practices.

This figure should be understood as guidance, not a certification. It encourages designers and developers to:

  • keep websites lightweight
  • streamline code
  • avoid unnecessary assets
  • consider the broader energy context of hosting and content delivery

It’s a prompt toward responsible practice, not a guarantee of environmental performance.

A website that reflects your values

When your work is grounded in sustainability principles, it’s natural to want your digital presence to reflect the same care.

Sometimes, though, websites feel misaligned with a brand’s ethos — visually polished, but technically heavier or built without much consideration of long-term maintenance or efficiency.

A responsibility-led website isn’t defined by a single number or metric. Instead, it’s shaped by:

  • thoughtful choices
  • clear intention
  • mindful design
  • an awareness of the systems behind the screen

These elements help your online presence feel more aligned with how you operate elsewhere in your business.

Designing responsibly with Divi (especially Divi 5)

Divi 5 introduces a leaner architecture and more efficient markup, giving designers a stronger foundation for building websites with responsible digital principles in mind.

Here’s how to apply those principles in practice:

Thoughtful hosting choices

Choose providers that are transparent about their energy sourcing and environmental commitments.

Lightweight Divi builds

Divi 5’s cleaner code output and reduced shortcode dependency allow you to create more streamlined pages when used intentionally.

Optimised assets

Use appropriately compressed images, minimal video and intentional animation. Avoid auto-play media or oversized files that add unnecessary weight.

Accessible, responsive layouts

Design pages that are easy to navigate, mobile-ready and supportive for all users — reducing friction and enhancing clarity.

User experience with intention

Simplify journeys. Clear pathways reduce confusion and help visitors find what they need quickly, supporting a smoother digital experience.

None of these practices guarantee a specific carbon output — but they do support a more mindful, efficiency-oriented approach to digital design.

The bigger picture

Responsible digital design goes beyond technical choices. It’s about creating a website that feels aligned with:

  • your values
  • your user experience goals
  • the way you work as a business

When your brand expresses depth, care and intention, your digital presence can reflect those same qualities — offering clarity, trust and coherence at every touchpoint.
