How the Sustainable Swap Suggester works
- Pick a category and what you are optimising for, since carbon and waste volume often point at different choices.
- Read the break-even use count. A reusable made from a heavier material only wins after it has replaced enough disposables.
- Start with the swaps you will genuinely sustain — an unused reusable is worse than the disposable it replaced.
FAQ
Is a cotton tote always better than a plastic bag?
No, and the break-even is high. Growing and processing cotton is resource-intensive, so a cotton tote needs dozens of uses to beat a thin plastic bag on carbon and far more on water. Whichever bag you already own and actually reuse is the right one.
Why does the metric change the answer?
Because carbon, water use, waste volume and toxicity do not move together. A swap that cuts plastic waste can raise carbon, which is why the priority you choose changes what gets recommended.
What matters most overall?
Using what you already own for longer, and the small number of large decisions — heating, transport, diet — rather than the many small purchases. Product swaps are the visible part, not usually the biggest one.
