Building Carbon Footprint Calculator
Convert your building's electricity and fuel use into annual CO2e emissions.
Planning estimate only, using standard emission factors. A puniq audit ties this to your actual meters, fuel logs, and the correct grid factor for your market.
About this tool
Every kilowatt-hour and litre of fuel your building burns has a carbon number attached. This calculator turns your annual electricity and fuel use into tonnes of CO₂e, so you have a clear baseline for ESG reporting, Vision 2030 and net-zero targets, or a green-financing application.
Enter your annual electricity, any on-site diesel or gas, and your grid emission factor. The default factor of 0.45 kg CO₂e/kWh is a typical GCC grid average, but you should use the published figure for your utility when you have it. We split the result into electricity (your Scope 2) and fuel (your Scope 1).
Why a baseline matters
You cannot manage what you do not measure. The biggest lever in most GCC buildings is electricity, because cooling drives 60 to 70% of the load. Knowing the split tells you where to act first: cutting kWh through smarter, vendor-neutral controls usually beats switching fuels. The equivalent-cars figure is just there to make the number tangible.
Frequently asked
What emission factor should I use?
Use the published grid factor for your utility if you have it. The 0.45 kg CO₂e/kWh default is a reasonable GCC average, but factors vary by country and year, so the right number tightens your result.
What is the difference between Scope 1 and Scope 2 here?
Scope 1 is direct emissions from fuel you burn on site (diesel generators, gas boilers). Scope 2 is indirect emissions from the grid electricity you buy. This tool separates them so you can see both.
Why is electricity usually the biggest share?
In the Gulf, cooling can be 60 to 70% of a building's load, and that runs on electricity. So for most buildings the fastest way to cut carbon is to cut kWh through better controls, not to change fuels.
Is this good enough for ESG reporting?
It is a solid baseline and screening estimate. For an audited or financed report you need verified meter data and the correct factors. A puniq audit produces a defensible, reportable figure.
