Why This Matters
Climate change can feel like an overwhelming problem that no single household can impact. But household decisions collectively account for about 70% of global emissions when you include the supply chains of products and services we consume.
This calculator helps you identify your biggest impact areas. For most families, transportation and home energy are the top two contributors. Knowing this helps you prioritize: switching to LED bulbs saves some CO2, but carpooling or an electric vehicle saves far more.
The goal isn't perfection — it's progress. Even small changes, multiplied across millions of households, create meaningful impact. Start with the highest-impact changes the calculator identifies and build from there.
