Our mission:

We want to help humanity reach a sustainable state of existence by quantifying, and making widely accessible, the impact of every choice we make

Climate Change is the biggest challenge of our time. The overwhelming majority of our daily activities are still based on processes that release greenhouse gases, and thus our way of life is unsustainable.

A radical change is required.

Information has to precede action. In this jungle of complex trade-offs, living truly sustainably has become difficult.

We use science, data and machine learning to automatically quantify the environmental impact of our daily decisions. We present this information in a simple and elegant way, empowering anyone to have a tangible and positive impact.

Our products
