greencode.ai, the website of ITEA GreenCode, the programme we lead, has been rebuilt and relaunched. On 26 September 2026 it moved from WordPress to static pages served from Cloudflare's edge network, and it now carries far more of the project's work: films, publications, researcher profiles, events and teaching, alongside the case for why the energy software uses matters.
A project about efficient software should have an efficient website.
A lighter site
Until September 2026 the site ran on WordPress on a virtual server in London. A first view of the home page transferred about 6,766 KB over 80 requests, and every request ran PHP and a database. The rebuilt site is a set of static pages generated in advance and cached close to the visitor, with no application server or database behind a page view. A first view of the home page is now about 1,719 KB over 33 requests. Images are recompressed and served as WebP, each page loads only the scripts it needs, unused styles are purged and the font is self-hosted.
Every page states in its footer how much data the view transferred and an estimate of the carbon it produced. The estimate comes from CO2.js, the Green Web Foundation's open-source library, using the Sustainable Web Design model. The green hosting page explains the method and what delivering the site has cost in carbon over its lifetime.
Films on every topic
The home and About pages open with an overview film, and the benefit pages, the topic pages and the long-read articles each have a narrated film of their own with captions, 25 in all. They are being published on the project's YouTube channel as well. A ten-minute long-form film brings the whole argument together, and you can watch it on our GreenCode page.
The case, benefit by benefit
Fifteen benefit pages set out what energy-efficient software delivers, from reduced energy use and lower total cost of ownership to longer device lifetimes, ESG data for CSRD reporting and green software certification. Nine key feature pages describe the parts of the pipeline. The climate case sets out the carbon arithmetic with its sources and assumptions, and the Future page describes where the project goes once the pipeline is built. Three long-read articles cover the energy of research software and high-performance computing, policy for the energy of software and AI, and mathematics and green AI.
The research, and the people behind it
- Publications: every paper and public deliverable on one timeline, newest first. Each has its own page with a synopsis, authors linked to their ORCID profiles, and the citation ready to copy in several formats.
- Researchers: a directory of the people doing the work across the consortium, filterable by institution and country, with a profile for each that lists their GreenCode publications.
- Partners: the 21 partners across 8 countries, each with a profile and logo.
Events and teaching
The events page opens on an interactive world map. Choose a country to see what the consortium has presented there, switch between past and upcoming events, and open any event for its own page, including the publication presented where there was one. The teaching and training page lists the courses and lectures in which partner universities teach energy-efficient and sustainable software, each linked to the institution's own page.
Staying in touch
Every page has a newsletter sign-up, and there is a contact form, a further resources page of standards, tools, guides and reports, a funding page and a page of thanks to the people who have supported the project. Analytics only run once a visitor has accepted them.
