Every time someone visits your website, data is transferred across networks and servers โ and that transfer consumes electricity and emits COโ. The Website Carbon Footprint Calculator estimates your site's annual carbon emissions based on the methodology from websitecarbon.com. You enter four values: page size in MB, monthly pageviews, hosting energy type (conventional or green), and your returning visitor ratio. The tool calculates annual COโ in kilograms, breaks it down by month and per visit, and also shows annual energy consumption in kWh. Results are converted into a tree equivalent โ how many trees would need to absorb COโ for a year to offset your site's emissions. A comparison simulation shows how switching to green hosting or reducing page size by 50% would reduce your footprint in real time. The copy result card button lets you share your grade and stats on social media instantly. All calculations run entirely in your browser โ no data is sent to any server. Note that this calculator uses a conservative energy factor of 1.805 kWh/GB, which may produce higher estimates than the newer Sustainable Web Design v3 model (~0.81 kWh/GB). Grades (A+ through D) are based on industry average benchmarks, not an official standard.
