Carbon Footprint Calculator
Calculate personal emissions from energy use, travel and everyday purchases
Estimate household emissions and compare practical ways to reduce them

CoolClimate Calculator estimates a household's carbon footprint from travel, home energy, food, goods, and services. Location, household size, and income establish initial defaults, which can be refined with mileage, energy bills, and spending information. Simple and advanced inputs provide different levels of detail.
The results separate categories and support comparisons with similar households. An action planner explores changes such as transport or home-energy choices, showing estimated emissions reductions and costs under its assumptions. Users can inspect those assumptions and save a report. A household can begin with a broad estimate, then add actual records to examine the activities contributing to it.
