Carbon Calculator

Your carbon footprint is a representation of the effect you, or your organization, have on the climate in terms of the total amount of greenhouse gases you produce (measured in units of carbon dioxide). Many of your actions generate carbon emissions, which contribute to accelerating global warming and climate change.

For example, when you drive a car, each gallon of gasoline you burn produces carbon in the form of carbon dioxide. Depending on the fuel efficiency of your vehicle and the miles traveled, a gasoline-powered car can easily generate its own weight in carbon dioxide each year. The average American is responsible for about 20 tons of carbon dioxide emissions each year, a far greater per capita number than that of any other industrialized country. In fact, the US accounts for more than 20% of the world's total greenhouse gas emissions. You can reduce your carbon footprint by driving a more efficient car, or driving less. You can also plant trees or help preserve forests to offset your emissions, since trees are a sink for carbon.

Reduce your Footprint in your Home

1. Seal and insulate your home
   Sealing air leaks and adding more insulation to your home is a great do-it-yourself project. The biggest leaks are usually found in the attic and basement. If you are planning to replace windows, choose ENERGY STAR qualified windows for better performance. Forced air ducts that run through unconditioned spaces are often big energy wasters. Seal and insulate any ducts in attics and crawlspaces to improve the efficiency of your home. Not sure where to begin? A home energy auditor can also help you find air leaks, areas with poor insulation, and evaluate the over-all energy efficiency of your home. By taking these steps, you can eliminate drafts, keep your home more comfortable year round, save energy that would otherwise be wasted, and reduce greenhouse gas emissions.
2. Heat and cool smartly
   Simple steps like cleaning air filters regularly and having your heating and cooling equipment tuned annually by a licensed contractor can save energy and increase comfort at home, and at the same time reduce greenhouse gas emissions. When it's time to replace your old equipment, choose a high efficiency model, and make sure it is properly sized and installed.
3. Look for ENERGY STAR qualified products
   When buying new products, such as appliances for your home, get the features and performance you want AND help reduce greenhouse gas emissions and air pollution. Look for ENERGY STAR qualified products in more than 50 product categories, including lighting, home electronics, heating and cooling equipment and appliances.
4. Offset your carbon emissions
   New wind turbines and new family dairy farm methane energy projects will deliver clean, renewable energy to the grid on your behalf, displacing power that otherwise has to come from burning fossil fuels.
5. Change 5 lights
   Change a light, and you help change the world. Replace the conventional bulbs in your 5 most frequently used light fixtures with bulbs that have the Energy Star and you will help the environment while saving money on energy bills. If every household in the U.S. took this one simple action we would prevent greenhouse gases equivalent to the emissions from nearly 10 million cars.
6. Be green in your yard
   Use a push mower, which, unlike a gas or electric mower, consumes no fossil fuels and emits no greenhouse gases. If you do use a power mower, make sure it is a mulching mower to reduce grass clippings (PDF, 8 pp., 1.59 MB, About PDF). Composting your food and yard waste reduces the amount of garbage that you send to landfills and reduces greenhouse gas emissions. See EPA’s GreenScapes program for tips on how to improve your lawn or garden while also benefiting the environment. Smart Landscaping can save energy, save you money and reduce your household’s greenhouse gas emissions.
7. Reduce, Reuse, and Recycle
   If there is a recycling program in your community, recycle your newspapers, beverage containers, paper and other goods. Use products in containers that can be recycled and items that can be repaired or reused. In addition, support recycling markets by buying products made from recycled materials. Reducing, reusing, and recycling in your home helps conserve energy and reduces pollution and greenhouse gases from resource extraction, manufacturing, and disposal.
8. Use water efficiently
   Saving water around the home is simple. Municipal water systems require a lot of energy to purify and distribute water to households, and saving water, especially hot water, can lower greenhouse gas emissions. Look for products with EPA's WaterSense label; these products save water and perform as well or better than their less efficient counterparts. There are also simple actions you can take to save water: Be smart when irrigating your lawn or landscape; only water when needed and do it during the coolest part of the day, early morning is best. Turn the water off while shaving or brushing teeth. Do not use your toilet as a waste basket - water is wasted with each flush. And did you know a leaky toilet can waste 200 gallons of water per day? Repair all toilet and faucet leaks right away. See EPA's WaterSense site for more water saving tips.
9. Spread the Word
   Tell family and friends that energy efficiency is good for their homes and good for the environment because it lowers greenhouse gas emissions and air pollution. Tell 5 people and together we can help our homes help us all.
