DC Carbon Footprint Calculator

Estimate annual CO2 emissions, carbon offset cost, and equivalent trees to offset your data center footprint.

Total annual electricity consumed by the facility including IT and overhead. If you know IT load in kW, multiply by 8,760 hours and PUE.
kWh
CO2 emitted per kWh of grid electricity. US average ~0.39 kg/kWh. Coal-heavy ~0.9, natural gas ~0.4, hydro/nuclear ~0.02.
kg CO2/kWh
Percentage of energy sourced from renewables (solar, wind, hydro). This portion is treated as zero-emission.
%
Ratio of total facility power to IT equipment power. Industry average ~1.58. Used to show overhead impact on emissions.
Market price per metric tonne of CO2 offset credits. Voluntary market ranges $5-$50/tonne.

Results

Annual CO2 Emissions:
Total annual CO2 emissions from grid electricity after subtracting renewables.
-metric tonnes
CO2 from Overhead (non-IT):
Emissions from facility overhead (cooling, lighting) based on PUE.
-metric tonnes
Carbon Offset Cost:
Estimated cost to purchase carbon offset credits.
-USD/year
Equivalent Trees Needed:
Mature trees needed to absorb equivalent CO2. ~22 kg CO2/year per tree (EPA).
-trees
Equivalent Driving Miles:
Equivalent passenger car miles producing same CO2. ~0.404 kg CO2/mile.
