Shopping green can make an important contribution to protecting the planet and conserving its resources.

Today’s consumer faces a wider range of choices than ever before, Add to that the steady stream of sales campaigns, and shopping smart only gets harder. To buy economically and reduce waste, safeguard health and protect the environment, you’ll need to follow some basic principles and have a clear idea of what you want.

1. Do Your Homework

Before making any major purchase, take the time to research it. Plentiful resources are usually available online. Avoid buying in a hurry, and don’t be persuaded by overenthusiastic salespeople. Sleep on it if necessary—you won’t regret giving yourself some extra time to think.

2. Take the Long View

Consider the running costs as well as the initial price of any item you buy. Many environmentally friendly products cost more to buy, but save you money in the long run. Choose items that are made to last. For example, pick a sofa that has a hardwood or steel frame rather than one made of softwood, which may break easily.

3. Skip the Disposable Option

Buy reusable products like washable cloth towels, handkerchiefs, serviettes(餐巾)and cleaning cloths rather than paper, single-use varieties. Avoid other disposable supplies like cups, glasses, and chopsticks, too.

4. Take the Local Route

Buy local products that are in season. It’s usually cheaper and fresher and has less harm to the environment. Markets and roadside stands are good sources. Some supermarkets also buy from local producers. Support it if you have one.

5. Avoid Wasteful Packaging

Better not buy products that have too much packaging. It’s estimated that approximately 10 percent of every shopping bill is actually paying for packaging—which you normally just throw away! Moreover, significant amounts of energy are used in the production of packaging. Purchasing refillable and renewable containers can also help cut this kind of waste.
