Our browser extension shows a product's ESG Score right on the shop's product page — and on Amazon, next to every search result. No second tab, no extra research: you simply carry on shopping.

Score, certificates and the category's top 5 — right beside the product, without leaving the page.
Every result carries its score, so you can compare before you click.
The same view in office supplies — recycled paper, its certificates and better alternatives.
And in IT procurement, where a single printer decision stays with you for years.
One click in your browser's store — that is all it takes.
Open your browser's store, click Add and confirm the installation. Tip: pin the extension to your toolbar afterwards, using the relevant browser icon — otherwise it stays hidden.
Click the extension's icon in your browser toolbar and enter your email address. We will send you a one-time code — there is no password to remember. Until you do this, the extension stays locked.

The extension needs access to the active tab, local storage and the login cookie. It has no access to your history or your other tabs.
To look up a score we send the product number — ASIN or GTIN — and your session token. No page content, no URLs, no shopping cart. The one exception: if you ask us to score a product we do not have yet, we also send its name, brand and link, so that we can identify it.
No analytics, no third-party scripts, no profiling. We do not earn anything from your clicks, and no manufacturer can buy a better rating.
One click in the popup pauses the extension. Widgets and the icon badge disappear straight away.
Just as the Nutri-Score does for food, the ESG Score puts sustainability on a single scale from 0 to 100 — based on category-specific criteria and a transparent, scientifically grounded methodology. The German association for supply chain management, procurement and logistics (BME) recommends it.
How the score is calculatedYes. The scores come from our database and are available to our customers only. You sign in exactly as you do on our website, with your email address and a one-time code.
Nothing on top. The extension is part of your ESG-Score.org access, free trial included.
Chrome, Edge and Firefox. For Chromium-based browsers such as Brave, Opera or Vivaldi you can simply install the version from the Chrome Web Store.
The extension tells you that there is no score for this product yet. You can then let us know with one click that we should add the product to our ratings.
The lookup runs in the background and results are cached. On search result pages we ask for up to 25 products in a single request.
No. The score follows the published methodology and the underlying data. There is no commercial way to influence it.
