The web industry is responsible for nearly 10% of greenhouse gas emissions, equivalent to the aviation industry. Consequently, eco-friendly web design is climbing the priority list for French and international companies conscious of their energy footprint. This article will introduce the concept of eco-friendly web design and provide a checklist of three major areas to improve your website’s eco-friendliness.

Understanding Eco-Friendly Web Design

Eco-friendly web design involves creating websites and e-commerce platforms that consume less energy and are more environmentally friendly. Given our growing awareness of our actions’ environmental impact, many are considering this design approach when creating or redesigning a website. Moreover, the main principles of eco-friendly web design can be applied to an existing site via simple optimizations.

Three Essential Steps to an Eco-Friendly Website

1. Select Green Web Hosting

Choosing ecological or “green” web hosting is the first step toward an eco-friendly website. Green hosting should adhere to the following ISO standards:

  • ISO 14001 – Environmental Management: This standard compels hosts to measure and reduce their activities’ environmental impact. It also aids in anticipating and controlling environmental risks.
  • ISO 50001 – Energy Management: This standard establishes a framework for hosts to set measurable energy performance objectives to gauge the effectiveness of their energy policy.

Furthermore, choosing a host that only uses renewable energy sources can enhance your eco-friendly efforts. The ideal host would meet all ISO standards, use renewable energy, and provide hosting performance tailored to your needs.

2. Design a High-Performance, Fast-Loading Site

The website’s loading time is an easily tracked indicator of its environmental impact. The longer the loading time, the more energy a site consumes. Each site, regardless of its size, plays a role in this.

To optimize a website’s loading time, you could consider these four critical measures:

  • Minimize the number of requests required to display your webpage (less than 50 is ideal).
  • Optimize and compress images to reduce their loading time (which also benefits your SEO).
  • Aim for a minimalist design by limiting unnecessary features, modules, and images.
  • Regularly clear unnecessary media and data from your server and databases.

3. Implement a Dark Mode Option for Website Navigation

Regardless of your website type, offering a dark mode can save electricity when users browse your site. This addition requires some CSS integration, but the cost of development and maintenance remains relatively low if considered early in the project.

There are three main ways to offer dark mode:

  • Enforce it during certain hours without user choice, although this limits its impact if your traffic mainly occurs during the day.
  • Propose dark mode upon site arrival, potentially affecting your conversion rate but raising awareness of its environmental benefits.
  • Enforce it on all users after a certain browsing period, with user consent and environmental rationale provided.

If you’re unsure about how dark mode might impact your conversion rate, develop it if your budget allows, then conduct A/B testing to assess its impact.
