Moment of Truth

After you have calculated your points for each category, add them together to get your carbon footprint score. The lower the score the better. If your score is less than 60 points, then you are making a small impact on your planet. If it is higher than 60, then you might want to look for some ways that you can reduce your impact.

Heat Advisory: Please be prepared for extreme heat. Bring water, stay hydrated and seek shade when possible.
