Tero - Save trees by browsing online

By: Tero
Tero turns your browser into a force of positive change and lets you fight climate change simply by browsing online.

Features & Capabilities

➤ How it works

  1. Tero changes your "new tab" page and includes incredible features and beautiful wallpapers.

  2. We replace some of the ads you see while browsing online with Tero ads, which allow us to save trees for free, simply by browsing online.

  3. Our shopping popup lets you save trees and earn cashback when shopping at our +80,000 partner stores.

➤ Key features

✓ Save trees when you open a tab, browser, or shop online ✓ Private and secure ✓ YouTube Adblock ✓ Customizations and beautiful background photos on your new-tab page ✓ Shortcuts to your favorite websites and apps ✓ News, updates, and notifications ✓ Custom search engines ✓ Manage your extensions from a simple and intuitive popup ✓ Keep track of your impact with our tree counters

➤ Your privacy and trust matters

We're interested in making an impact, not in your data. We are committed to protecting your privacy and using your data responsibly. The ads on our extension are delivered by our advertising partners, who may collect anonymized data in order to show you ads you'll be interested in.

We don't track the websites you visit or the content you view online. What you do online is you business and yours alone. Our extension's permissions allow us to replace ads online and detect if the website you are on is one of our partners.

➤ We don’t plant trees

☆ "Planting trees is good. Saving existing forests is better." - Rainforest Trust ☆

We made an active decision to save existing trees rather than plant new ones because compelling studies show that planting trees won’t be enough to tackle climate change and that efforts on rainforest conservation lead to a more sustainable and lasting change.

Here are three facts you might not know:

✓ Forest conservation needs 30x less land to have the same climate mitigation outcome as planting trees. ✓ Forest protection efforts help protect the natural habitat of thousands of species and local communities that depend on natural resources. ✓ Forest conservation typically costs half as much as forest restoration efforts.

➤ Tero vs. alternatives

☆ Ecosia ☆ We love Ecosia! Although many people think we are competitors, we are actually not. We recommend you use Ecosia’s search engine with the Tero extension to maximise your impact.

☆ OceanHero ☆ Like Ecosia, OceanHero is a search engine that can also be used in Tero. It's a great combo to save both rainforests and oceans!

☆ Tab for a Cause ☆ They are a great option if you want to support numerous charities, but they're only a new-tab page with limited functionalities.
