Most people want to reduce their environmental impact but have no idea where to start. Carbon footprint calculators exist, but they're either oversimplified (just flights), locked behind corporate paywalls, or require manual data entry that nobody maintains. There's no open, programmatic way to estimate carbon impact from everyday activities like commuting, diet, energy use, and purchases. An open API and toolkit would let developers build carbon awareness into any app.
