Did you know that the CO2 footprint of an average search is estimated at 0.2 grams? Not so with Ecosia. We recently built our own solar plant, so that we can run our servers on clean power. This is even better than buying renewable energy from existing plants, as the plant can deliver clean energy to the grid and replace electricity derived from fossil fuels.
By planting trees and offsetting its energy use with renewables, each search with Ecosia actually removes 1 kg of CO2 from the air, which makes Ecosia a carbon-negative search engine. Here’s the math: an average search generates around 0.005 € of revenue. It costs roughly 0.25 € to plant a tree, which means that Ecosia can plant one tree every 50 searches. On average, these trees will each remove 50 kg of CO2 during an expected 15 year lifetime.
This means that if Ecosia were as big as Google, it could absorb 15% of all global CO2 emissions! That’s enough to offset vehicle emissions worldwide.
