Budgets
W3C Sustyweb: https://w3c.github.io/sustyweb
Setting targets and limits regarding your product or service is important for keeping a sustainable
mindset. Using budgets, you can declare the remits of which you will work within to ensure your
emissions do not fall outside (and monitor your progress through development).
Success Criterion - Environmental Budget
(Machine Testable)
The product team has defined, baselined, and
documented clear sustainability and
environmental budget criteria that cover the
page, user-journey, and digital service levels
and metrics (such as a CO2.js score) that are
approved by relevant product stakeholders.
Success Criterion - Performance
Budget (Machine Testable)
Tools such as a performance budget
exist to determine the maximum size
(goals) your app or website can weigh to
reduce the data transfer and HTTP
request impact (using metrics like Google
Lighthouse).
