While the associated costs of this weekend's royal wedding continue to soar, at least one aspect of the event is being tamped down.

According to the website BusinessGreen, planners have been working behind the scenes to reduce the environmental impact of the festivities.

Besides carbon offsets, Clarence House officials have said all documents will be printed on recycled paper and FSC-certified wood is being used in the building of the media stands. Where possible, renewable energy will also be utilized — though specifics about the type of green tech was not given.

"[Sustainability] is considered by both Clarence House and Buckingham Palace in terms of everything it does," an official told the site, "so you wouldn't be wrong to assume that the food and flowers will be seasonal and sustainably sourced."

In terms of the royal wedding dinner, I know for a fact that it will feature organic and locally sourced ingredients. Award-winning Swiss chef and restaurateur Anton Mosimann, a close friend of Prince Charles, is scheduled to cater the event.

Mosimann is known for a type of cooking he calls cuisine naturelle — choosing to prepare dishes that do without such ingredients as butter, cream and alcohol. In an interview with the UK Guardian, he said “Everywhere I cook I always find a local person to source good, fresh local ingredients.”

ABC News is also reporting that Kate and William have chosen London-based floral designer Shane Connolly to oversee the arrangements at Westminster Abbey. "Connolly is known for his 'sustainable approach to floristry,' which uses live growing plants and trees," the site says. The couple plans to donate or replant most of the flowers and trees after the ceremony. 

Of course, you can make the royal wedding as green as you like, but as MNN has reported, the influx of visitors to London is likely to cancel out any environmental goodwill. Last week, the city officially surpassed the annual EU limits for air pollution — a violation that carries a $300 million fine.
