About CarbonTracker.io
We build simple tools that help real people cut real emissions — no guilt trips, just numbers and actions.
On the homepage you’ll find live electricity grid carbon intensity for the U.S. and U.K., updated periodically. Our tools estimate travel, home energy, and food-related emissions. The blog focuses on what changes pay off in the real world.
We use public APIs and transparent assumptions. If an API is down, we say so, and you can enter manual values where appropriate.
