With celebs such as Emma Watson, Anne Hathaway, and Emma Roberts leading the charge, sustainable fashion is hotter than ever 鈥 gone are the days of green looking 鈥済ranola,鈥 (a la Cher鈥檚 brother Josh in Clueless). These days, your fave fashion brands, home goods stores, and charities are all getting in on the eco-friendly game, and we couldn鈥檛 be more excited, since, more importantly, it鈥檚 a super easy way to give back to the planet that gives us so much. With Earth Day happening April 21, we鈥檙e making it our mission to help you do just that by rounding up some of the most eco-friendly brands and events around. Happy shopping!

1. Burt鈥檚 Bees鈥 Bring Back the Bees Campaign: As Pretty Little Liars鈥 star Troian Bellisario clued us in recently, through May 7 you can purchase one of four limited edition Bring Back the Bees lip balms ($3) to ensure that the company will plant one of up to 5,000 wildflower seeds in your honor to help feed the bee population, which is quickly dying off. Currently at 46,140,000 wildflowers pledged as of press time, the brand needs your help in the form of a purchase (or even a selfie with the hashtag 鈥#selflesselfie,鈥 which also counts for a seed) to hit its goal of two billion.

2. S鈥橶ell x UrbanStems Collab: Through April 30, you can nab one of two specially designed S鈥橶ell bottles (the same company that brought you that sold out Lilly Pulitzer bottle collab) made from non-toxic steel paired with a responsibly grown UrbanStems flower bouquet. Choose from The Sequoia ($65), which includes a floral arrangement of snapdragons, purple poms, and sunflowers, as well as a wood-patterned nine-ounce bottle (the proceeds from which will go to fund clean-water drinking programs in Madagascar through UNICEF up to $800,000 committed by S鈥橶ell), or The Scout ($65): a box filled with four items that will benefit four separate Earth-friendly initiatives. There鈥檚 a S鈥橶ell nine-ounce stainless steel bottle (proceeds will benefit worldwide forest restoration efforts, 鈥淧ush Garden鈥 bee-friendly wildflower seeds (10 percent from which will go to the Pollinator Partnership), Harper鈥檚 McCaw dark chocolate (to help rainforests in South America), and pins to show off your activism.

3. Westfield鈥檚 Refashion the Future Event:Westfield Shopping Centers in NYC, LA, San Francisco, San Jose, San Diego, and Washington DC will be partnering with I:CO and offering up rewards cards to some of your fave brands (think Forever 21, H&M, and Cotton On), in exchange for your old hand-me-downs. Not only will you be getting discounts on some new threads, but you鈥檒l be helping someone in need while cleaning out your probably-too-packed closet. Sounds like a pretty sweet deal to us!

4. Reformation鈥檚 Factory Tours: Hollywood鈥檚 favorite eco designer, Reformation (beloved by such celebs as Taylor Swift), will be allowing customers a look behind-the-scenes with a factory tour of its grounds led by the company鈥檚 CEO, Yael Aflalo, in order to change perceptions about factories and how sustainable fashion is made. Save your spot here. (Photo via Reformation)

5. Target鈥檚 Car-Seat Trade-In: Instead of junking that old car seat, Target has a much better idea: Through April 30, you can take your used seats into Target to be recycled or upcycled into new products to get an upgrade at 20 percent off: an initiative they expect to save landfills up to 700,000 pounds of car seat waste. As the band鈥檚 chief sustainability officer Jennifer Silberman said, 鈥淚n honor of Earth Month, we wanted to make it easy for guests to do something positive for the planet and their communities.鈥 (Photo via Target)

6. IKEA鈥檚 鈥淪ustainable Living Your Way鈥 Event: Between the hours of 9:30am to 6pm, IKEA stores will be showing its customers how to start living green with a simple RSVP. What鈥檚 more, you can also bring gently used furniture in for donation in exchange for coupons, receive discounts on sustainable bamboos and LED bulbs, and win prizes (including IKEA gift cards and a SLADDA bike).
