The fashion industry is responsible for 10% of all annual global carbon emissions, roughly 2.7 billion tons a year. This is more than all international flights and maritime shipping combined! Nowadays, companies promote purchasing products, but this extension helps users take a step back from consumerism to rethink the sustainability of their choices.

What it does

Our Chrome extension incentivizes consumers to make ecofriendly purchases by rewarding their ecofriendly purchasing habits. This extension offers an ecofriendly rating for each clothing product online along with econews about companies, and gives points to users based on the sustainability of their purchases that can be converted to gift cards at sustainable companies, like Patagonia and Seventh Generation.

How we built it

We built a chrome extension and webapp and linked the two. On the backend, we used Python, and for the frontend, we used React and Bootstrap. Flask allows us to switch between pages on the webapp. To create our feature that aggregates recent econews about companies and aggregate it to a paragraph summary, we used openAI and metaphor.

Challenges we ran into

Our biggest challenges were web scraping to read the product description from EBay to assist in our product ratings. We attempted to use OCR for image recognition but found an alternative metric to use. We also had difficulty deciding on the weightage of metrics for our ecofriendly rating.

Accomplishments that we're proud of

We are so proud of our team for building this! This is a useful, impactful, and realistic Chrome extension that can help both people and the planet.

What we learned

We learned the effect of the fashion industry, the factors that go into sustainability, and technologically, how to create both a Chrome extension and a web app and connect the two. We also learned that every member has a different strength, so we leveraged those while learning from each other throughout the hackathon.

What's next for Sustain

We want to expand Sustain onto sites aside from C2C sites (like big clothing brand sites!). We also want to include additional metrics into the product ratings to ensure that we are rating products and rewarding consumers fairly for their efforts. Ideally, we also include an educational component so that consumers can continue to stay informed.
