Amy Smart and Carter Oosterhouse, who tied the knot in Novmember 2011, are sharing some wedding advice with engaged celebs like Hayden Panettiere.

According to E! Online Smart and Oosterhouse had a green wedding and made sure to recycle and minimize waste on their special day. The couple dished to E! News at the Environmental Media Awards on Saturday about having green weddings and advice they have for engaged stars.

“We tried our best,” Smart said. “We tried to use as much compostable, recyclable, local ingredients and at the end of the day we had half a bag of trash.”

The couple also talked about how their shared interest in the environment helped them get together.

“We met through the Environmental Media Association and we were assigned to adopt a school garden together to mentor,” Smart said. “Then, we became friends for a long time... we were both in relationships [at the time].”

Oosterhouse chimed in saying, “Because of that we feel like we have to come to [the EMAs].”

Just Jared reports that Hayden Panettiere also attended the EMAs on Saturday. Panettiere was given the Futures Award, which honors her for her work as an environmental activist.
