QR codes are everywhere — menus, posters, packaging — but their role in sustainability is just beginning to be understood. At first glance, they seem simple. Scan, open a link, get some info. But when used well, that small action can spark a big shift in behaviour.

"Every little bit helps." It's a phrase that you'll hear often in sustainability. And while the sentiment is well-meaning, it's also misleading.

But without data, even the best reuse schemes risk becoming guesswork.

Tracking carbon in reuse systems isn't just smart—it's essential. Learn why it matters and how to do it right.

Carbon footprints and carbon credits are a starting point on how we can begin to be more sustainable and fight against climate change.
