In Florida, 41% of all carbon dioxide emissions are produced in the transportation sector and 51% from electricity production. That’s a whopping 92% of all emissions from only 2 sectors.
This makes it easy for the individual – you – to do a simple, rough calculation of your family’s carbon footprint by looking at your gas and electricity purchases. How?
Estimating YOUR Family’s Carbon Footprint
First, let’s take TRANSPORTATION.
Every gallon of gas you pump into your vehicle produces 19.37 pounds of carbon dioxide emissions. PERIOD. It doesn’t matter if you drive a Ford pickup, an SUV, or a Prius hybrid. The carbon content of the gasoline is the same and it’s ALL emitted into the atmosphere. What efficiency does is reduce the number of gallons you consume for all the miles you drive, and that can only be a good thing. But if you also reduce the number of miles you drive that’s even better.
So how many pounds of carbon dioxide do your family vehicles emit in a month?
Multiply no. of fills per month x gallons per fill x 19.37 pounds
Example: 4 fills per month x 20 gallons per fill x 19.37 pounds = 1,550 pounds per month
Put another way that’s 3/4 ton each month, about 9 tons per year.
Next, let’s look at ELECTRICITY.
In FPL’s service territory, every kilowatt-hour of your monthly electric bill accounts for about 1.21 pounds of carbon dioxide. In this case CO2 emissions are dependent on your electric utility’s fuel mix.
FPL power plants are primarily natural gas (50%), coal (22%), nuclear (20%). For comparison, power generation is primarily natural gas (38%), coal and petroleum coke (28%), oil (17%), nuclear (13%) across Florida. If you’re outside FPL a very rough calculation would be 1.39 pounds of carbon dioxide per kilowatt-hour, but it really is utility-specific because every utility power mix is different.
So how many pounds of carbon dioxide does your family electric bill represent each month?
Multiply “kWh this month” from your FPL bill x 1.21 pounds.
Example: 1,000 kWh (an average bill) x 1.21 pounds = 1,210 pounds per month
Unlike vehicles, your electricity bill will change month-to-month based on seasonal heating and cooling requirements. So your family’s consumption will vary. Home energy efficiency measures also have a large effect, although the reductions in consumption are difficult to measure.
Coming back to the original question “How many tons of carbon dioxide is your family responsible for?”
In the examples given this family is responsible for 1,550 pounds CO2 per month due to its gasoline purchases and 1,210 pounds due to electricity consumption.
Their carbon footprint is 2,760 pounds per month, about 17 tons per year.
The best way to combat global climate change is for everyone to know what their carbon footprint is, to monitor and to improve it on a daily basis.
Calculate your family’s carbon footprint, teach your family where your numbers came from and get them involved in reducing it further. It should be fun and it will definitely benefit your home and your planet.
