Fast and Simple.

Your ZIP code lets us use the right electricity grid emission factor and climate data for your region.

ⓘ How we do this Home age, type, and size are significant predictors of overall energy use when combined with local climate. We only estimate likely energy use of a home like yours in your area based on national datasets that also include typical energy use of electronics and appliances. We don't actually have data on your specific home, but similar homes in similar regions tend to perform predicably similar and often remain well within the uncertainty of trying to apply more detailed data. Below with the the slider you can make adjustments for things like renewable energy.

Home energy is a large slice of a household's footprint. Rough guesses are totally fine.

Use the slider to enter miles driven per year across all vehicles in your household. 10,000–15,000 miles per vehicle is typical in the U.S. Rough estimates are fine. ⓘ How we derive travel emissions Vehicle gasoline and diesel emissions are calculated using fuel combustion emission factors from the U.S. EPA GHG Emission Factors Hub. Electric vehicle energy use (kWh per mile) is based on average efficiencies from U.S. Department of Energy fuel economy data, with electricity-based emissions determined using the EPA eGRID regional grid mix based on the ZIP code provided. Aviation emissions are estimated using published passenger-distance emission factors converted to flight hours using commercial passenger aircraft flight distances and times. Additional radiative forcing effects from contrails and other high-altitude processes are not included.

✈️ Try to estimate gate to gate times. Reference: NYC–LA ≈ 5.75 hrs · Chicago–DC ≈ 2 hrs · Dallas–LA ≈ 3.5 hrs · Denver–Seattle ≈ 3 hrs · Minneapolis-Atlanta ≈ 2.5 hrs · Atlanta-Orlando ≈ 1.5 hrs (one way)

Include clothing, electronics, home goods, personal care, entertainment. Exclude groceries, restaurants, travel, rent & utilities. ⓘ Where does this come from The U.S. Environmentally-Extended Input-Output (USEEIO) model provides the foundation for goods and services emissions factors. These data are matched to consumer spending on goods and services provided regularly by the U.S. Bureau of Labor Statistics, Consumer Expenditures. We exclude sectors related to food (covered below) and utilities (covered in the home section).

Diet is one of the highest-impact personal choices for greenhouse gas emissions.

🌱 Plant-based diets can generate 50–70% fewer greenhouse gas emissions than meat-heavy diets.
