"Standards move too slowly for our regulatory timeline"

How GSF used an AI-assisted assembly process to bring 14 experts from 15 organisations to consensus in ten weeks — a process that previously took years — proving a new model for accelerating green software standards development as regulations tighten.

The Problem

The bottleneck isn't technical complexity — it's coordinating dozens of stakeholders at the speed regulations require

Traditional standards development takes years. The SCI specification — widely celebrated as moving at unprecedented speed — still took over three years from inception to ISO certification. By the time specifications reach final form, regulations have evolved, technology has shifted, and the window for influence has narrowed. The bottleneck is not technical complexity. It is the challenge of coordinating dozens of stakeholders with competing priorities, different terminologies, and divergent views on scope, accuracy, and implementation.

The problem was becoming urgent. The EU Green Digital Coalition, the NY Corporate Climate Accountability Act, and evolving GHG Protocol guidance were all creating pressure for organisations to report on digital sustainability. A standard that arrived two years too late would be a standard nobody adopted.

The human-in-the-loop approach made objections visible and resolvable — a deliberate decision gate rather than the traditional model of circulating documents and hoping for feedback. What had been an opaque social process became an explicit technical one.

The Journey

From a blank page to consensus in ten weeks

ISO standard proves consensus is possible — but slow

April 2024

When the SCI Specification achieved ISO 21031:2024 status, it validated that a multi-stakeholder, consensus-driven process could produce a globally recognised standard. But even this celebrated achievement had taken over three years from inception. The question became: how do you keep the rigour of consensus while compressing the timeline? GSF had 17 active projects. If each required 3+ years of traditional consensus-building, the pipeline would be unmanageable.

W3C and GSF announce formal collaboration

September 2025

The Green Web Foundation, active in both communities, brokered a strategic collaboration between GSF and W3C to advance sustainable web development through shared research, standards development, and measurement frameworks. The collaboration focused on developing SCI for Web — extending the proven SCI methodology to web applications, covering the full delivery chain: servers, networks, third-party services, and end-user devices.

The AI-assisted assembly

September–November 2025

Fourteen members with web-specific expertise were assembled: Alekh Gupta (Google), Alexander Dawson (ClimateAction.tech), Asim Hussain (GSF), Camille Fassett (WattTime), Chris Adams (Green Web Foundation), Daniel Schien (University of Bristol), Facundo Armas (Globant), Florent Morel (Amadeus), Francesco Fullone (GrUSP), Mathias Uhlitzsch (Evosoft), Nisha Ramachandra (Accenture), Raghava Rao Battina (HSBC), Riccardo Pomato (Microsoft), Ryan Sholin (Electricity Maps), and Thiago Falcao Silva (NTT DATA). Participants answered structured questions about measurement accuracy and adoption complexity. An LLM synthesised their responses into draft content. The group reviewed and refined through multiple rounds. In contentious areas, participants revised until all objections were resolved.

Consensus reached in ten weeks

Late 2025

The assembly resolved core tensions: a specification that is technically accurate but unused serves no purpose, and a widely used metric that lacks credibility also fails. Three key principles were agreed: accuracy proportionate to control, mandatory disclosure of boundaries and assumptions, and integration into existing workflows over added complexity. The scope was defined — web applications delivering value through browser interfaces via HTTP/HTTPS — with third-party services explicitly required within the measurement boundary.

Specification development begins

Q1 2026

With the design foundation established in weeks rather than months, SCI for Web entered active specification development. The process is now proven and replicable — the AI-assisted assembly model can be applied to future GSF standards work, compressing consensus timelines across all new specifications.

Almost all of us use the web daily, and like everything else, we need to make using it more sustainable. By defining a standard for measuring website emissions, we make it easier for people to request greener digital services, for responsible technologists to build them, and to reach the fossil-free internet we all need.

Who came together

The people who made it happen

AH

Asim Hussain

Executive Director

Green Software Foundation

Conceived and led the AI-assisted assembly process, participated as an assembly member, and championed the web sustainability agenda.

CA

Chris Adams

Director of Technology and Policy

Green Web Foundation

Proposed SCI for Web, brokered the W3C collaboration as an active member of both communities, and leads the SCI for Web project.

DS

Daniel Schien

Academic

University of Bristol

Brought academic rigour to the web measurement methodology, drawing on years of research into the environmental impact of internet infrastructure.

In their words

"We believe that the opensource SCI Specification will catalyze a new era of sustainable innovation within the technology industry. And, hopefully, is another indicator for how important collective contributions from the opensource community are to scale green software. "

Henry Richardson

Senior Analyst, WattTime; Co-chair, Standards Working Group

"A specification that is technically accurate but unused won't serve its purpose, and a widely used metric that lacks credibility also won't serve the purpose. "
