Sustainable Web development

We need to change the Internet

The internet accounts for 3.7% of global CO2 emissions, a figure that is expected to double by 2025. Fortunately, we have methods to make positive changes – today.

Paths to a CO2-neutral website

The first step is to measure the current climate footprint. We analyse selected pages with several different independent tools and provide concrete recommendations for improvement.

Photos and video are low-hanging fruit. We reduce file sizes 50-90% with no visible loss of quality. The result is a better user experience and a smaller carbon footprint.

In WordPress you can easily download redundant code for e.g. webshop, newsletters and fonts that are not used. We’re cleaning that up for better performance and lower energy consumption.

Data centres use huge amounts of power. We’re happy to host your WordPress website at reputable Oderland in Sweden and CO₂ offset our total energy consumption by 500%

With independent before and after measurements, we document the reduction of your website’s climate footprint. This can be part of your company’s climate goals, or leverage for your marketing.

Why us?

Why you should talk to us!

Because sustainability is as essential to you as it is to us. Because you prefer durable solutions to actual needs. Because you welcome everyone to your website.

A whole lot greener

Our websites pollute less than 90% of the average. The target is < 0.25 g CO2 per page view.

Modern techniques

New file formats and hand-picked compression settings typically mean half as heavy websites.

We are furiously fast

… or at least our websites are. You don’t have to take our word for it – it can be measured and experienced.

Full transparency

Our results come from professional insight and care. We share all the methods with you.


The Danish Ehlers-Danlos Association

A patient association needs an easily accessible website that is secure and long-lasting. We’ve built that for them. See for yourself how – maybe it will inspire you.

A technical and content reboot

Like any other website five years old, the site needed a thorough overhaul. The result was a fresh website with relevant content imported, a solution with concrete and measurable improvements:

  • 95% reduction in website CO2 emissions.
  • Well-tested web accessibility and WCAG compliance.
  • Complete respect for visitor privacy and GDPR.
  • Perfect Google Lighthouse and Core Web Vitals scores.
  • Robust and secure operation with updates and monitoring.

No two websites are the same and every need should be considered separately, but perhaps the case of the Ehlers-Danlos Association website will inspire you to improve yours.
