Reduce waste & support reforestation with every cup

Coffee lovers & bubble tea lovers: do you want to reduce your environmental footprint? Ditch single-use cups by simply bringing your own reusable cup when buying drinks to-go. Every 5 cups you save is 1 tree planted!

Meet BYO - an app where small, individual actions create meaningful collective impact for sustainability

**BYO works in 3 easy steps**

1. Bring your own cup to a participating cafe
2. Use the app to scan cafe’s QR code when ordering your drink (let the cafe staff know)
3. Ta-da! Congratulate yourself for avoiding single-use cups and supporting reforestation efforts.

**New version update**

See Cafe Info - You can now see all BYO participating cafes in a map. Read each cafe's profile to learn more about them.

Get Social - Invite your friends to join BYO and track each other's cups saved and trees planted. Sustainability is more fun together!

Get Rewarded - Save more cups to access exclusive deals from local small businesses.

**Why bring-your-own-cup?**

Did you know Metro Vancouver threw out 174 million disposable cups in 2020? This linear system of take-make-dispose (resulting in over-extraction and growing landfills) is an enormous stress on our planet. One effective way to reduce consumer waste is to avoid it in the first place. At BYO, we encourage users to skip disposable cups by bringing their own — replacing disposable culture with a more eco-friendly, reuse culture.

**Feel empowered**

Being a sustainability champion should feel empowering! Track your cups saved and trees planted while seeing how your impact contributes to BYO’s combined, collective impact. Never again say “I’m just one person, what good can I do?”

Download the app today to be among the first to try BYO!
