# CO2 signal

**Service:** UX/UI Design / Webflow  
**Deliverables:** UX/UI Design, Webflow  
**Live site:** https://www.co2signal.com/

##### **About the project**

In addition to Electricity Maps' paid API, we wanted to create a subproduct of the API that are free for individual users and developers to use.

The CO2signal API gives you access to where the electricity in a specific region comes from, how it was produced and how much carbon was emitted to produce it. All free for non-commercial use.

##### **My role**

As this project has been a side project in the activities for Electricity Maps, the website was created in a design sprint that took the project from sketching and designing the interface pixel by pixel to implementing the design in Webflow and launching the website in 7 consecutive days. I have been working as the individual contributor in the sprint from start to finish.
