The countdown to the royal wedding is on! While Prince William and Kate Middleton have only revealed a few details about their big day, we couldn’t help but think about ways they could green the royal wedding. Here are 5 ways the royal couple can make the the royal wedding just a little bit greener!

Over 1,900 invitations have been sent out for the royal wedding, creating tons of paper waste! Think about how many trees would be spared the fate of becoming a royal wedding invitation, if Kate and William had used recycled paper. Certain companies even allow customers to send in their used paper products to be recycled into beautiful invitations. RSVP returns can then be sent back after the wedding to be recycled again into thank you cards, making for more sustainable guest correspondences. While the couple has set up both public and private wedding websites, which saves on having to send out paper event updates, another eco-friendly modern touch would have been digital "evites" and RSVPs.

One of the most talked about parts of the royal wedding is the gown the future princess is going to walk down the aisle in. While the name of the designer has been kept tightly under wraps, speculation about the material and style has been swirling since the engagement was announced. Using an alternative fabric such as hemp silk or 100% organic cotton not only makes for an eco-chic look fit for royalty, but also makes for a comfortable and breathable dress. That might come in handy when greeting a thousand guests and millions of television viewers.

An eco-friendly choice William has made is re-using his mother, Princess Diana’s, royal engagement ring which she wore during her engagement in 1981. Passing along family heirlooms not only adds a personal touch to the proceedings, but also saves precious natural resources like diamonds and gems. To take it a step further, William and Kate could also green the royal wedding bands. Resetting old family diamonds is a great way to recycle and add a personal touch to the royal wedding day.

Using fresh and local produce is always a good way to give back to the local economy and to reduce the carbon footprint of the event. The menu is already set to include local produce such as blood oranges and walnuts. Adding local delicacies such as roasted duck to the menu could further the use of a locally themed meal.

What do you get the couple who has everything? An eco-chic gifting option is setting up an alternative registry where people can donate to various charities of the couple’s choosing in place of bringing a gift, and Will and Kate have done just that!
