Public access
Faster, lighter and more accessible services can improve usability across slower networks and less powerful devices.
The engineering case
Procurement can reward measurable outcomes instead of vague sustainability claims.
A public-sector digital standard can require evidence for accessibility, speed, transfer efficiency, caching, technical integrity and machine-readable public information. The goal is not to prescribe one framework or vendor; it is to make avoidable digital waste and exclusion measurable during procurement and ongoing operation.
Infrastructure efficiency
Reducing unnecessary transfer and processing can lower repeated demand across networks, devices and data-centre infrastructure.
Machine-readable public information
Clear structured identity and canonical source pages help search and AI systems retrieve public information with less ambiguity.

Public Policy · Digital Sustainability
Digital sustainability policy can treat public websites and online services as measurable infrastructure: services should be accessible, efficient, technically robust, discoverable and proportionate to the task they perform. Procurement can specify outcomes without mandating a particular commercial vendor or framework.
Public digital services operate at exceptional scale
A small inefficiency on one visit may become substantial when repeated across tax portals, licensing systems, healthcare information, education services and municipal websites. Governments therefore have a unique opportunity to reduce avoidable transfer, waiting and processing through procurement requirements that are measurable rather than aspirational.
Procure outcomes, not technology brands
A digital sustainability requirement should not mandate HIC, a CMS, a cloud provider or a particular framework. It can require measurable outcomes: accessibility evidence, defined performance budgets, transfer limits, caching policy, resilient semantic HTML, secure response headers and clear machine-readable public information. Vendors remain free to choose the implementation that meets the requirement.
Accessibility and efficiency are public-access issues
Citizens do not all use new phones, fibre connections or unlimited data. Lighter, faster and more accessible public services can reduce friction on slower networks and lower-powered devices. Efficiency therefore supports inclusion as well as infrastructure sustainability.
Machine-readable public information is becoming infrastructure
People increasingly reach government information through search engines, assistants and AI systems. Public bodies should publish clear canonical source pages, explicit dates, stable entity identities and accurate structured data so machines can retrieve authoritative information without guessing which source is current.
A practical procurement framework
Require a pre-launch baseline, publish measurable budgets, test representative templates, preserve evidence, reassess after material changes and disclose modelling assumptions. For high-impact services, include manual accessibility testing and real-user performance monitoring. The objective is continuous engineering accountability, not a once-off badge.

Key terminology
Definitions that remove ambiguity.
- Digital public infrastructure
- The online systems and information services through which public institutions deliver services and authoritative information.
- Performance budget
- A predefined measurable limit for characteristics such as transfer size, requests, loading time or JavaScript cost.
Questions people ask
What this means in practice.
Is HIC asking governments to mandate one commercial platform?
No. The policy argument is for measurable digital outcomes and transparent evidence. HIC is one implementation of that approach.
Can digital sustainability be measured perfectly?
No single model is perfect. A defensible standard should distinguish direct measurements from modelled consequences and publish its assumptions.
