You can use the following online calculator to get a rough “ballpark” estimate of your personal or family’s greenhouse gas emissions and explore the impact of taking various actions to reduce your emissions.

​The calculator is broken into three sections: ​

1: Estimate your current total household emissions.

2: Explore actions you can take to reduce your greenhouse gas emissions, energy use, and waste

       disposal costs.

3: See how much you can save (in dollars and emissions) by taking the actions you chose in Section 2.
