Even before you are actually doing your weekly shopping you can start being eco-friendly. Make a list of everything you need to buy so that you can save on making any unnecessary trips in your car again, just because you forgot buying the potatoes. Just a bit of pre-shopping preparation can save fuel, money and effort.
When buying items like tissue rolls or bags, get stuff that is made from recycled materials. Buying items made with recycled-content materials means that fewer natural resources, such as trees, were used to produce the products.
