How Much CO₂ Does Your Air Conditioner and Refrigerator Emit?
We all take great pleasure in coming home after a hot day to a sweetly cool room or pulling a cold drink from the fridge, but have you ever wondered how much carbon dioxide gets emitted from your air conditioner and refrigerator?
Besides this household distinction, the appliances also state their part to contribute to our carbon footprints. So in basic human terms-no technical science, missing the actual impact, and how it can be reduced in normal life!

Your Refrigerator emits 0 kg of CO₂ annually.
Total Carbon Footprint: 0 kg of CO₂ annually.
How Much CO₂ is Emitted When an AC Runs?
Air conditioners could be the lifelines in summer, but they sure suck up a whole lot of electricity within any home. The amount of CO₂ they emit usually depends on:
- Number of hours of use in a day
- Months of use in a year
- How eco-friendly is your electricity grid (measured in kg CO₂/kWh)
Calculation to Clear the Clutter
- Let us consider a 1.5 kW air conditioner set to run for 8 hours a day for a period of 6 months in a year.
- Assume that in your area, one kilowatt-hour of energy burnt leads to the emission of 0.5 kg CO₂. Let us estimate the annual damage done by the air conditioner:
Energy Used=1.5×8×(6×30)=2160 kWh per year
Carbon Footprint=2160×0.5=1080 kg CO₂ per year
That’s 1.08 metric tons of CO₂ every year—the same as driving a car for about 5,000 km!
How Much CO₂ is Released by a Refrigerator?
Unlike air conditioners, refrigerators do not ever get unplugged. They run continuously day and night for an entire year. So emissions will thus add up. The carbon footprint of a refrigerator depends on:
- How much electricity it uses (kW).
- How many cycles the compressor makes on and off during the day.
- The carbon intensity of the electricity you use.
The Numbers
Say your fridge used 0.2kW and ran 12 hours daily, as it is not always 100% of the time.
Energy Used=0.2×12×365=876 kWh per year
Carbon Footprint=876×0.5=438 kg CO₂ per year
That’s about 438 kg of CO₂ per year, or roughly what 7 trees absorb in a year.
How the Carbon Footprint from Your AC and Fridge Can Be Reduced
We already know how much carbon dioxide these appliances release, so let’s introduce a few measures that may help us reduce their effects-and keep all the comfort.
For air conditioners:
- Consider an upgrading to an energy-efficient model-Inverter ACs operate at 30-40% lesser consumption of energy.
- Adjust your thermostat to 24-26°C (75-78°F)-With every degree lower, you increase energy use by 5-10%.
- Use ceiling fans-They distribute cool air, thereby decreasing your air conditioner dependence.
- Seal leaks and insulation-Reduces temperature losses, less air conditioner load.
For refrigerators:
- Go for an ENERGY STAR-rated fridge-These models run with about 20% less power.
- Set the right temperature-Keep checks on the temperature-adjust your freezer to -18°C and fridge to 3-5°C.
- Don’t overload it-Over-stuffing the refrigerator blocks air flow, making it work harder for the compressor.
- Defrost regularly-A build up of ice makes the appliance less effective.
The Bottom Line:
While your measure of air conditioning and refrigeration may seem fairly insubstantial, their contributions amount to a sizable volume of CO₂ losses each year. If you ever wondered how much CO₂ would an air-conditioning unit or how much would a fridge, now you know-the figures are real, and the effect is great.
But there is also good news: you don't need to part with these appliances if fewer emissions are your goal-you just have to use them more smartly! Simple changes such as setting them at reasonable temperature levels, moving to energy-efficient models, and cutting down on wastage can make your carbon footprint smaller and keep you comfortable.
Any action? Perhaps turn the thermostat down on your AC or maybe check whether your fridge ought to be upgraded? However small or big, it contributes a lot towards making our planet greener.
