- Benchmark: Compare with industry average.
- ESG Report: Generate report for sustainability reporting.
- Optimization Tips: Concrete actions to reduce your footprint.
How it works
- Enter the website URL — the tool scans all pages and calculates the carbon footprint based on page size, hosting and data transfer
- Get a detailed report with carbon footprint per page, total annual emissions, industry benchmark and prioritized reduction measures
- Implement the measures and run a new scan to document the improvement — generate sustainability badge for the website
Use cases
- Companies with sustainability goals needing to document digital climate footprint — get concrete figures and measures for website emissions
- Web developers and agencies wanting to offer green web development — use Eco Audit as a tool to measure and optimize client websites
- Public organizations with sustainability reporting requirements — document website climate footprint as part of the total sustainability report
Why use Eco Audit?
Sustainability is no longer optional. More and more customers, partners and regulators require documentation on climate measures. A climate-friendly website is a concrete, measurable measure that shows the company takes sustainability seriously — and Eco Audit gives you the data you need to document it.
Climate optimization is also performance optimization. Most measures that reduce carbon footprint — image compression, code minification, caching — also improve website loading speed. So you get both lower emissions and better user experience and SEO ranking.
Communicate sustainability visually. With Eco Audit sustainability badge you can show customers that your website is climate-optimized — a concrete and credible signal that distinguishes you from competitors who only talk about sustainability without documenting it.
FAQ
- How is CO2 emission calculated?
- We measure page size, server type, and estimate power consumption based on established models.
- Can I use this in ESG reports?
- Yes, the report is designed to be included in sustainability reporting.
- What is a good result?
- Under 0.5g CO2 per page view is considered green. The average is about 1.76g.
- Does it work for all websites?
- Yes, you can analyze any public URL regardless of CMS or technology.
- Can I compare with competitors?
- Yes, run analyses on competitor websites and compare CO2 footprints side by side.
- How is the carbon footprint calculated?
- The calculation is based on page size (bytes transferred), hosting provider energy source (green vs fossil), number of server requests, user device and network infrastructure. We use recognized methodologies from The Green Web Foundation and the Sustainable Web Design model.
- How accurate are the measurements?
- The measurements provide a good estimate based on available data. Accuracy depends on factors that vary — user device, network speed and server load. The estimates are most useful for comparison over time and between pages, not as absolute figures.
- What is a good carbon footprint for a website?
- An average website generates approximately 0.5-1.0 grams of CO2 per page view. Websites under 0.5 grams are considered climate-friendly. The best websites get down to 0.1-0.2 grams per page view through optimization and green hosting.
- Can I use the sustainability badge on my website?
- Yes, the tool generates a visual badge with the website carbon footprint that you can embed on the website. The badge updates automatically when you run new scans, so it always shows updated figures.
