Overview
View sustainability and ESG data for Amazon products. Click the icon to see scores.
Leif ESG Checker helps you shop more sustainably on Amazon. Click the Leif icon in your toolbar while viewing any Amazon product page, and Leif will look up the brand's ESG (Environmental, Social, and Governance) rating and display it in a small side panel. No extra tabs. No research. Just clear sustainability data while you shop. HOW IT WORKS 1. Browse Amazon like you normally do. 2. When you want to check a product, click the Leif icon in your browser toolbar. 3. Leif reads the product's identifier from the page you're viewing and looks it up against our sustainability database. 4. A panel appears showing the brand's ESG score and rating. 5. Click "View Full Details" to open the full supplier profile, find greener alternatives, and compare brands on shopleif.com. WHAT YOU'LL SEE • ESG Score — a 0-100 score based on a brand's environmental, social, and governance practices, where data is available. • Rating tier — a quick "Great" to "Below Average" tag so you can gauge a brand at a glance. • Greener Alternatives — open shopleif.com from the panel to find similar products from more sustainable brands. • Save to Cart — bookmark products you're interested in to compare later. Saved items are stored only in your browser, not on our servers. WHY LEIF? Most people want to shop more sustainably but don't have time to research every brand. Leif does that research for you, pulling from public ESG data and disclosures so you can make informed choices in seconds. Shopping sustainably should be easy, not a chore. Learn more at https://shopleif.com PRIVACY Leif does not sell your data. When you click the Leif icon on an Amazon product page, the extension reads the product identifier and product metadata (title, brand, breadcrumb category) from that page and sends it to our backend services (Google Firebase, Google Cloud Functions, and Algolia) to look up the sustainability rating. We do not collect your name, email, browsing history outside of Amazon product pages you actively view, shopping cart contents, order history, or payment information. Full privacy policy: https://shopleif.com/pages/privacy.html AFFILIATE DISCLOSURE Leif participates in the Amazon Associates Program. Outbound product links from Leif to Amazon.com may contain an affiliate tag. This does not affect the price you pay and does not influence our ESG ratings — our scoring methodology is independent and based solely on publicly available data.
