Performance with a conscience

Sustainable Website Calculator

The calculator makes sustainability practical by focusing on the things teams can actually change: fewer heavy assets, cleaner journeys, better defaults, less repeated transfer, and fewer unnecessary third-party scripts.

Diagnostic intent

Avoidable page weight

This public tool is designed to capture a sharper lead, prepare the right review context, and route the visitor toward a credible HAAM audit, sprint, or implementation conversation.

NGOs

Useful when the team needs a clearer outside signal before spending more time or budget.

climate teams

Useful when the team needs a clearer outside signal before spending more time or budget.

cultural sites

Useful when the team needs a clearer outside signal before spending more time or budget.

content-heavy organizations

Useful when the team needs a clearer outside signal before spending more time or budget.

Inputs

What the visitor provides

The tool keeps the intake small enough to complete, but specific enough to support useful follow-up.

  • Website URL
  • Important pages
  • Traffic range
  • Known media-heavy sections

Review model

What HAAM should inspect

The first version collects the request. A full backend can attach evidence collection, screenshots, scoring, and reviewer approval behind the same page.

  • Page weight, asset types, and largest visible offenders
  • Image format, dimensions, compression, and repeated downloads
  • JavaScript volume, hydration cost, and third-party scripts
  • Hosting and cache signals when detectable
  • Low-carbon redesign opportunities linked to user experience

Lead magnet output

What the prospect should receive

The goal is not a giant automated report. The goal is a compact, credible artifact that makes the next conversation easier.

  • Low-carbon website brief
  • Asset reduction backlog
  • Performance and sustainability priority map
  • Before-and-after measurement plan

Example findings

The language should be specific, conservative, and useful

These examples show the type of signal the tool is meant to surface. Real findings should only be sent after evidence is collected and reviewed.

Example 1

A small set of large images may create most of the avoidable transfer.

Example 2

Third-party scripts can weaken sustainability, speed, privacy, and trust at the same time.

Example 3

The most sustainable fix may also be the best conversion fix: remove unnecessary weight from the first journey.

Conversion path

Route the visitor into a serious project request

The call to action preloads the selected tool into HAAM start flow so the request has context before a conversation begins.
