Sustainability is the best gift you can give this year.   BY KATIE BOURQUE Dec 16, 2019   Here's the dilemma: You want to find the right gift for your dad, your grandma, and maybe even your pet — but what you don't want to do is contribute to all the unnecessary waste that occurs during the most wonderful time of the year. In fact, one study found that we throw away 25% more trash between Thanksgiving and New Year's Day than any other time of the year. Yikes. So if your idea of the perfect gift includes being kind to the environment, then you're in the right place.   People throw around words like "environmentally-friendly," "green," and "earth-friendly" — but the Good Housekeeping Institute prefers the term "sustainable," which means that there is at least one specific way that the product benefits the environment in the long run. "Sustainability, for us, is using the Earth’s resources in such a way that future generations can meet their needs," explains Birnur Aral, Ph.D., director of the Health, Beauty & Environmental Sciences Lab at the Good Housekeeping Institute. So the products on this list all have at least one sustainable attribute, if not more.   If you're looking to gift sustainable clothes, check out our list of the best sustainable fashion brands, but if you're in the market for stocking stuffers, white elephant gifts, and other last-minute presents, our sustainable holiday gift guide features the best eco-friendly gifts you can buy in 2019:
