Digital Sustainability and Energy Efficiency: The IFG Protocol for a Green Web
Last updated: March 21, 2026
The energy footprint of code
The web is responsible for a significant share of global CO2 emissions. Every redundant line of code, every unused script, and every unoptimized image requires extra processing cycles in data centers and more battery power on user devices. The sustainability of an eCommerce store is not just about product packaging, but also about the efficiency of the digital infrastructure that sells them.
The ESG approach applied to development
Designing Shopify stores that consume less bandwidth and less energy is not just an advantage in terms of loading speed: it is also a concrete contribution to reducing the digital carbon footprint.
How I reduce the technical weight of a store
- Asset optimization: next-generation image formats (WebP, AVIF) and video compression to reduce data transfer.
- Code cleanup: removal of technical debt and unused third-party apps, which reduce the workload on servers and mobile devices.
- Hosting on Shopify infrastructure, which uses 100% renewable energy for its servers.
Performance as a responsible choice
By reducing Total Blocking Time (TBT) and improving Largest Contentful Paint (LCP), a site achieves the user's goal with fewer interactions and less screen-on time — a benefit for both conversion and overall energy consumption.
Accessibility as part of sustainability
Following WCAG 2.1 standards and the European Accessibility Act ensures that a store is usable by anyone, regardless of physical abilities or the device used — including older devices or slow connections, which remain usable longer when the site is lightweight.
What I offer clients
I consider the technical efficiency of the store a useful metric for sustainability reporting. Every migration or redesign I undertake is an opportunity to replace heavy and obsolete systems with leaner, low-impact architectures.
