These days, many people are more environmentally aware.

Now, even weddings are going green.

Brides and grooms are saying “I do” to environmentally friendly weddings. As they take their vows, they’re doing their part to save the planet.

It’s “An Inconvenient Truth,” but weddings use up a good amount of natural resources.

From yards of bleached white lace to guests flying in for the ceremony, weddings can take their toll on Mother Earth.

However, a new trend has wedding white being exchanged for ecological green.

“A green wedding is a state of mind. It's all about having a socially conscious celebration where the couple is looking for ways to give back with their wedding,” said Kathleen Murray of TheKnot.com, a wedding-related Web site.

Holly Rawson and Gary Smith were in a green wedding state of mind right from the start.

“One of the aspects that motivated us the most about how we could have an environmentally green wedding was my children,” said Smith.

The couple ditched the diamond in favor of a natural pearl. They used recycled paper for invitations and made centerpieces out of branches. All of their ideas were done without losing the traditional feel of their big day.

“It came out really well in the end. Everybody had a good time. It was very elegant,” said Rawson.

Meghan Meyers of Portovert Magazine said, "There are so many stylish choices out there and a range of choices."

At a time when weddings average nearly $30,000, being kind to the earth could be good for the purse.

“You're dealing with buying things locally, which can cost 40 percent less. You're buying things that can be reused or have been used before and these are all options that are in fact less expensive,” added Meyers.

Green wedding goods included recycled paper invitations, organic wines and foods, eco-friendly bridesmaid gifts, biodegradable and recycled plates for the reception and even hemp wedding gowns.

There are special bridal registries in which couples can donate to green causes to make up for resources the event uses up.

“We calculated our guests coming and going. We then bought carbon offsets to be used to build new wind farms,” said Smit.

Rawson said, “I had my big, poufy dress and everything looked gorgeous and everybody had a good time."
