To take the most effective decisions, especially at a personal level, one should rely on accurate, scientifically based data. Carbon footprint data however is not easily accessible and sometimes requires to make further calculations to compare different choices. To answer this question I have co-developped Scirious Gecko, a research initiative on sustainability. Scirious Gecko is an extensive and thorough investigation of carbon footprint data. We publish accessible blog articles in the hope of making carbon data readable for everyone.
