Calculation method of CO2
1. A transparent calculation method

kgCO2e / kWh of the country where the servers are located: Depending on the energy mix of each country, the carbon intensity of electricity varies.

255 (kgCO2e / kWh) x 1.805 x 344 Average gain in KB / 1000 = 3,5gCO2eq
2. Estimate the traffic of a website

Now that the average gain per page is calculated, we have to estimate the average number of page views per month.

6 255 Number of visitors per month x 5 Average number of page views per visit
= 31 275 Average number of page views per month
3. An estimate of the CO2 gain / year

Here is the final calculation to give an estimate of the CO2 gain allowed by Cloudimage per year

345 Average gain per page (gCO2eq) x 5 Average number of page views per visit x 12 month
= 345 g Average gain per year of CO2
