Turning climate values
into climate action

Many of us want to do something meaningful about climate change, but knowing what to do—and whether it actually makes a difference—can be difficult.

We created OffsetC to make climate action simpler, more transparent and
easier to connect to everyday life.

We're starting with gasoline. OffsetC identifies your gasoline purchases,
estimates the emissions associated with the fuel you buy, and
gives you a simple way to offset those emissions
through a portfolio of vetted carbon projects.

But gasoline is just the beginning.
Our goal is to help individuals better understand the climate impact of everyday activities
and make it easier to take meaningful action when they choose to.

Why OffsetC?

We believe climate action works better when people can understand what they're paying for and why. That's why we:

  • Show how we calculate emissions

  • Explain how carbon projects are evaluated

  • Make the underlying project research available for anyone who wants to dig deeper


We do the homework—and you can check our work.

Our Origins

The idea took shape during the 2024 Climatebase Fellowship, where a multidisciplinary capstone team worked together to develop the original OffsetC concept.

After the Fellowship, we kept going. Members of the original team continued to contribute, experienced advisors joined the effort, and OffsetC evolved from a capstone project into the product we're launching today.
