We use the industry-leading dataset

Ecologi Zero uses the most comprehensive carbon footprinting dataset of its kind to calculate your carbon emissions. We're one of the first businesses to use the new and industry-leading dataset from Small World Consulting and carbon accounting expert Prof. Mike Berners-Lee. We include all seven greenhouse gases under the GHG Protocol, so you can be sure you're getting your journey to net-zero off to a great start.
