Carbon (Offset) Challenge
The Carbon Offset Challenge is focused on the belief that reducing our carbon footprint is easier than we think.

The Problem
Climate change is real and it’s up to all of us to help make the difference. There are real effective ways we can all participate and do better. Many people want to make a difference but may not know how to begin. Our Carbon Offset Challenge is a way for every person to make small changes in their daily lifestyle.
Our Solution
Example Dashboard

We designed the Carbon Offset Challenge and accompanying tool to show users how minor adjustments in daily habits can add up to reduce significant emissions.
We encourage users to track their daily habits to learn how our actions can change our greenhouse gas emissions. By participating in this challenge you can see how minor adjustments to your daily habits add up and help clean up the planet.
Our Impact

School Resources
We worked with schools throughout Los Angeles county to provide materials, a carbon accounting toolkit, and a dashboard for classrooms to compete for emissions reductions.

Corporate Toolkit
We partnered with a variety of corporations to train staff on simple ways to reduce greenhouse gas emissions, including Mattel and Honest.
