About Ecoki

What you will find here

Who is behind Ecoki

Ecoki is run by Georgi Todorov, an eco activist and entrepreneur. Georgi publishes the guides on this site and is responsible for its tools and data.

The idea is simple. Most people and most small businesses want to do something about their footprint, and the first obstacle is finding a number they can trust. Ecoki exists to remove that obstacle.

How we handle data

Every figure on Ecoki comes from a named public source, and the source is shown on the page where the figure appears. We currently use the Global Carbon Budget, the U.S. Energy Information Administration, Ember, the Energy Institute and Eurostat, in several cases through Our World in Data.

Three rules apply to every dataset:

• Numbers are generated directly from the source files, not typed in by hand.
• Each page states the year the data refers to and what the figure does and does not include.
• Where a source is an estimate, we say so and point to the official alternative.

The calculators give estimates for planning and comparison. For a formal carbon report, use the emission factors published by your national authority.

Where Ecoki came from

Ecoki began as an eco-lifestyle blog, and its reviews and green-living articles are still in the archive. In 2026 the focus moved to measuring emissions, with the first calculator, a set of carbon guides and the data section.
