- Gather your gas, electricity and credit card bills. Then visit one of the following carbon calculators:
- Enter one month of each bill (good), use one winter and one summer bill (better), or use 12 months of each bill (best).
- If you want a Carbon Calculator that does not require finding bills try this one: https://climatehero.me.
- Make sure you save a copy of your results.
- For more clarity, you can measure your carbon footprint on all 3 calculators (even better than best!). The footprints will likely be different because they are all estimates. Save your results for week 51!
