The tips on this site are all given a Green Leaf Rating. That’s a scale of one to five leaves, with one being super easy or cheap to do and five being more difficult or more expensive to do.
In terms of impact, the easy or cheap tips will be things that mean you aren’t contributing to a problem anymore, but the overall impact will be small until thousands of us are doing it. (So share the tip!). The more difficult or expensive tips will have an bigger impact.
Do what you can.
