Tree-Nation's website emits 2.30 g of CO2 per visit, 6.4× the worst passing grade.

The numbers behind it

Annual figures cover the 28 pages I measured and estimated organic search traffic only, so the real total is higher. Coverage is published so you can judge how representative the number is.

One visit ≈ a 10-watt LED bulb for 28 minutes. A year of estimated search visits to the pages measured ≈ driving a new car 740 km. What these numbers mean
