Important things you can influence for a low carbon footprint are:
- How do you heat and how much? Gas heating is surprisingly bad in the US due to the high amount of methane leakage
- Do you drive a lot in a combustion car, or even worse, fly?
- What kind of food do you eat? As a rough guideline, dairy and meat is pretty bad and beef much worse. Also the stuff that has to be brought in by plane.
Living in nature often makes it harder to have a low carbon lifestyle and the things often associated with "good for nature" like reducing plastic waste and organic products are often worse carbon wise.
