Personal Emissions Calculator

EPA has developed tools to help individuals (and households) reduce greenhouse gas emissions and take action. Businesses and organizations interested in educating their employees and members about what they can do at home to help protect our climate can also use these tools.

Use this online calculator to obtain an estimate of your personal greenhouse gas emissions or your family’s greenhouse gas emissions. Then move on to the next section of the calculator to explore actions you and/or your family can take to lower your emissions while reducing your energy and waste disposal costs. For each action you choose to take, the calculator displays the amount of emissions you could avoid and how that amount relates to your total emissions.

Instructions for using the calculator:

  1. Allow yourself 10-15 minutes to enter the data.

  2. To get the most accurate results, gather your recent electric, gas, and/or oil bills so you can use real numbers for your household’s energy consumption.

  3. After entering data, use the TAB key to continue moving through the calculator.

  4. The calculator is designed to give you a rough “ballpark” estimate of your emissions and the savings you may achieve from taking certain actions. If you have more specific information (i.e. square footage of your home), try using one of the calculators listed below.

This calculator provides an estimate of household greenhouse gas emissions resulting from household energy use and waste disposal, and it gives you information you can use to identify ways to reduce your personal greenhouse gases. The What You Can Do section of the climate change site identifies 30 action steps that individuals can take to decrease greenhouse gas emissions, increase the nation's energy independence, and save money.

Transportation

On average, how many miles do you put on your car(s)?


Per Week Per Year

231 miles/week is about average in the United States per vehicle.

 

What is the average gas mileage for your car (miles per gallon)?


If you don’t know your car’s fuel economy, you can look it up at fueleconomy.gov.


12,100 pounds is about
average per vehicle over a year.

Home Energy

What is your average monthly gas bill?


$105 is about average in the United States for a household of two people.

Our calculations assume that you pay $13.83/thousand cubic feet


11,000 pounds is about average for a household of two people over a year.

What is your average monthly electric bill?


$100 is about average in the United States for a household of two people.

Our calculations assume that you pay 10 cents/kWh. We estimate your emissions based on the national average mix of fuels used to generate electricity. Your actual emissions may be higher or lower depending on your electricity provider's power mix.


16,290 pounds is about average for a household of two people over a year.

What is your average monthly fuel oil bill?


$130 is about average in the United States for a household of two people.

Our calculations assume that you pay $2.37/gallon


14,500 pounds is about average for a household of two people over a year.

Waste

Based on the number of people in your household, the box at right shows your estimated greenhouse gas emissions from waste. However, if you currently recycle certain materials, your waste emissions may be lower.

Total Waste Emissions Before Recycling


2,020 pounds is about average for a household of two people over a year.

Which of the following products do you currently recycle in your household?

 

 

Do you recycle newspaper?

Yes  No

What You Can Do to Reduce Emissions

On the Road

 

 

Amount of CO2
you can avoid per year

Are you in the market for a new car? Buy a vehicle that gets more miles per gallon than your current one.


more miles per gallon

The Fuel Economy Web site can help you find efficient vehicles.


pounds


percent of your total emissions

Give your car a break. Reduce the number of miles you drive by this amount.


miles Per Week    Per Year

When running errands, combine trips. Using mass transit, carpooling, telecommuting, biking and walking are also good options.


pounds

At Home

 

 

Amount of CO2
you can avoid per year

Turn down your heating thermostat by degrees Fahrenheit on winter nights.

Dropping the heat at night can make a difference.


pounds


percent of your total emissions

Replace 75-watt incandescent light bulbs with 25-watt ENERGY STAR lights. (Enter the number of bulbs you will replace.)

You'll get the same amount of light for less energy and lower monthly bills. By replacing the five most frequently used lights in your home with ENERGY STAR qualified lighting, you can save about $60 each year in energy costs.


pounds


percent of your total emissions

Replace your old refrigerator with an ENERGY STAR model. Will you take this action?
Yes   No

New refrigerators, especially ENERGY STAR models, cost much less to operate than old ones.


pounds


percent of your total emissions

Replace old gas or oil furnace or boiler with an ENERGY STAR model. Will you take this action?
Yes  No 

New models are much more efficient and cheaper to run.

Turn up your air conditioner thermostat by degrees Fahrenheit in summer.

You'll save money as well as reduce your emissions.

Replace single-glazed windows with ENERGY STAR windows. Will you take this action?
Yes   No



This step can save you a bundle in cold or hot climates.

*Emissions from waste and emissions savings from recycling are expressed as carbon dioxide equivalents.

For a more detailed analysis of fuel costs and emissions from your car, visit EPA’s and the Department of Energy’s Fuel Economy Web site.

For more detailed estimates of your home energy use (electricity, gas, and oil) and emissions, use ENERGY STAR’s Home Energy Yardstick tool. The ENERGY STAR site also provides ideas on a wide range of energy-saving products.

For information on climate change and waste, visit the Waste section of the What You Can Do section of this Web site. EPA has developed emissions calculators to help individuals and organizations determine the greenhouse gas impact of their purchasing, manufacturing, and waste management, which are available on the Climate Change and Waste Tools page.

A spreadsheet version (Microsoft Excel, 63kb) of the calculator is also available; it includes descriptions of the formulas used in each step of the calculator.

For an explanation of the assumptions and sources used by this calculator, click here. Keep in mind that average per person emissions estimates or per capita emissions estimates are usually derived from national estimates of GHG emissions, which include GHG emissions from all sources in the U.S., including industrial emissions (emissions from manufacturing of goods and services). As a result, if you compare your estimates from the personal emissions calculator to per capita emissions in the U.S., they may differ significantly.
