SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This skill addresses the hidden environmental impact of web development by identifying energy-intensive elements that standard speed tests often overlook.

Core Features & Use Cases

  • EcoIndex Scoring: Provides a standardized French methodology grade (A-G) for your site's ecological efficiency.
  • Carbon Impact Estimation: Calculates estimated CO2e and water usage per visit to make environmental impact tangible.
  • Actionable Waste Identification: Pinpoints heavy images, unused code, and inefficient third-party scripts that bloat your site.
  • Use Case: Use this before a major launch to ensure your site is as lightweight as possible, or to provide a measurable before-and-after report for CSR initiatives.

Quick Start

Run the eco-audit skill to analyze the environmental footprint of your currently deployed website.

Frequently Asked Questions about eco-audit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I calculate the EcoIndex score and carbon footprint of my Next.js application?▼

To calculate the carbon footprint of a Next.js application, you can run an eco-audit that analyzes page complexity, request counts, and resource weight. It generates an EcoIndex grade and estimates CO2e and water usage per visit.

What is EcoIndex scoring and how does it measure web sustainability?▼

EcoIndex scoring is a French methodology that grades a website's ecological efficiency from A to G. It measures web sustainability by analyzing page complexity, DOM elements, and resource weight to identify energy-intensive elements.

Do I need the PageSpeed Insights API to estimate my website's carbon emissions?▼

Yes, you need the PageSpeed Insights API to estimate website carbon emissions. The audit requires integration with this API alongside local deployment verification to accurately measure page performance and environmental impact.

Can I identify unused code and heavy third-party scripts causing carbon waste on my site?▼

Yes, you can identify unused code and heavy third-party scripts causing carbon waste. The audit pinpoints inefficient resources, heavy images, and bloated scripts to generate actionable optimization patches for your deployment.

What's the best way to generate a before-and-after sustainability report for CSR initiatives?▼

The best way to generate a sustainability report for CSR initiatives is to run an eco-audit before and after a major launch. It provides measurable carbon impact estimates and EcoIndex scores to track environmental waste reduction.
