Offset your Carbon Footprint!

This calculator estimates the amount of CO2 emissions from your plane, long distance train, commuter train, and car travel and your home energy usage. This audit is an estimate of your CO2 emissions and may not be exact. Learn more about our research at trees.org/post/carbon.

Fill in as many sections below as possible to offset your carbon footprint. You are able to save and come back to your work by clicking at the top or bottom of this screen. A tax receipt will be sent to the email provided below after completing your donation. 

Your Commute by Car

Where do I find this? Estimate the total number of gallons of gasoline you use per week. 

On average, unleaded gasoline emits about 19.56 pounds of CO2 per gallon.

Estimated number of gallons of gasoline you use per week:
multiplied by 52 weeks and multiplied by 19.56 pounds of CO2 per gallon equals
total pounds of CO2 emitted per year.
Your Travel by Plane

Where do I find this? Estimate the total number of miles you travel by plane per year. 

On Average, a plane emits about .55 pounds of CO2 per passenger mile.

Estimated numbers of miles you travel by plane per year:
multiplied by 0.55 equals
total pounds of CO2 emitted per year.
Your Travel by Long Distance Train

Where do I find this? Estimate the total number of miles you travel by long distance train per year.

On average, a long distance train emits about 0.30 pounds of CO2 per passenger mile.

Estimated numbers of miles you travel by train per year:
multiplied by 0.30 equals
total pounds of CO2 emitted per year.
Your Travel by Subway

Where do I find this? Estimate the total number of miles you travel by subway per year. This can typically be found on your local subway's website.

On average, a commuter train emits about 0.25 pounds of CO2 per passenger mile.

Estimated number of miles you travel by subway per year:
 
multiplied by 0.25 equals
total pounds of CO2 emitted per year.
Your Home Energy Use

Where do I find this? On your monthly electric bill your monthly energy use is listed. Add up your energy use totals from the past 12 electric bills.  

On average, electricity sources emits about 0.99 pounds of CO2 per kWh.

On average, 1 therm of natural gas emits about 12.08 pounds of CO2

Total Electricity Use:
kWh/Yr multiplied by 0.99
Total Gas Use:
therms/Yr multiplied by 12.08
equals
total pounds of CO2 emitted per year.
Your Totals
Your total emissions for the year are:
Converted into metric tonnes, this is:
Trees for the Future's agroforestry projects in Sub-Saharan Africa sequester CO2 through tree planting and land restoration at a cost of $3.45 per metric tonne of CO2. Therefore, the total cost to offset your annual CO2 emissions is: $
