About Leif List - Sustainability Scores
Leif List helps you shop more sustainably without the homework. Click the
Leif icon in your toolbar while you're on an Amazon product page — or on
one of our partner brand sites — and Leif looks up the brand's
sustainability score and shows it in a small side panel.
No extra tabs. No research. Just a clear rating while you shop.
HOW IT WORKS
1. Shop like you normally do, on Amazon or a partner brand's website.
2. When you want to check a product, click the Leif icon in your browser
toolbar.
3. Leif reads what product you're viewing and looks it up in our
sustainability database.
4. A panel appears showing the brand's score and rating.
5. Click "View Full Details" to open the full brand profile, find greener
alternatives, and compare brands on leiflist.com.
WHAT YOU'LL SEE
• Sustainability Score — a 0-100 rating based on a brand's environmental
and social practices, shown where we have verified data.
• Rating tier — a quick "Great" to "Below Average" tag so you can size up
a brand at a glance.
• Greener Alternatives — open leiflist.com from the panel to find similar
products from more responsible brands.
• Save to Cart — bookmark products you're interested in to compare later.

WHY LEIF?
Most people want to shop more sustainably but don't have time to research
every brand. Leif does the digging for you, pulling from public data and
company disclosures so you can make an informed choice in seconds.
Shopping sustainably should be easy, not a chore.

PRIVACY
Leif does not sell your data. When you use Leif on a supported product
page (Amazon or a partner brand site), the extension reads the product
identifier and basic product details (title, brand, category) from that
page and sends them 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 beyond the product pages
you actively check, shopping cart contents, order history, or payment
information. Full privacy policy: https://www.leiflist.com/pages/privacy.html
AFFILIATE DISCLOSURE
Leif participates in the Amazon Associates Program and in affiliate
partnerships with select brands. Outbound links from Leif may contain an
affiliate tag, which can earn us a commission at no extra cost to you.
This never affects the price you pay and does not influence our ratings —
our scoring is independent and based solely on publicly available data.
