This calculator allows you to estimate a portion or all of the greenhouse gas emissions you would like to offset from any of the sources below. We recommend offsetting a particular emissions source or your emissions total from all sources on an annual basis. You can also do so for a single event or multiple years. You can also make a secure custom and/or recurring donation by visiting our Donation page. There will be a link back to this form on that page.

Enter the information requested below, filling out only the applicable fields, and click the "calculate" button for the total offset cost. Thank you!
