Ecosia operates a mission-locked, steward-owned search engine that plants trees and invests heavily in renewable energy, achieving genuinely low operational emissions (102 tonnes) backed by third-party audit. Its core weakness: unquantified Scope 3 emissions from reliance on Microsoft Bing and Google infrastructure, and no formal science-aligned decarbonisation pathway despite aggressive climate commitments.

Ecosia is a Berlin-based search engine that redirects advertising revenue to reforestation and climate projects. Founded in 2009, it functions as a for-profit B Corp with steward-ownership preventing extraction of profits. The company is positioned as an ethical alternative to Google and Bing, embedding environmental action into its business model rather than treating it as a corporate add-on.
