MIT Center for Civic Media | Innovating civic media tools and practices together with communities

Sourcemap (Graduated)

Sourcemap is a social network built around supply chains, enabling collective engagement with where things come from and what they are made of.

How might communities use it?
An open-source project, Sourcemap provides resources for calculating the carbon footprint and geographic spread of various products and services, including consumer electronics, travel, and food.

At what stage of development is it?
We are deploying Sourcemap through in-depth case studies with designers and business owners in product design, hospitality, and food and drink. The Sourcemap team is actively seeking collaborators and pilot study participants to develop the tool for general use.
