How to use this: Pick a scenario button at the top to get started. Then slide the controls in the cards below to match your family’s home, cars, trips, food, and shopping. Everything updates right away. The green box shows your carbon footprint per person, the line chart shows how close you are to the 1.5 °C path, and “What you changed” ranks your moves by how much carbon they save. Curious where a number came from? Open the sources panel. When you’re done, copy the link at the bottom to save your work or share it with your class.
Your levers held constant; only the electric grid gets cleaner at the rate you set. Black dashes: 1.5 °C lifestyle path.
Household tonnes per year, US average vs. your scenario.
Move any lever. Each change is ranked here by the tonnes it saves for the whole household.
The link below encodes every slider. Anyone who opens it sees exactly this scenario.
Interaction pattern inspired by En-ROADS, created by Climate Interactive and MIT Sloan. This simulator is an independent household-scale model and is not affiliated with them.
Everything runs in your browser. Each lever feeds one equation; the total is the sum. Emissions are CO₂-equivalent (CO₂e) unless a source reports CO₂ only. The model covers what a household directly controls; it leaves out the public share of infrastructure, government and business investment, which is why it lands below the ~17.5 t per-capita US figure that counts every source.
