Planning a Sustainable Wedding: Love Without the Carbon Footprint

Love might be in the air on your wedding day; unfortunately, so are carbon emissions. The average Australian wedding emits about 21.5 tonnes of carbon dioxide, which is more than a typical household produces in an entire year. From the menu to the bridesmaid’s dresses, most aspects of a wedding come at a cost to the environment. If you’re looking to make your big day as sustainable as possible, it’s essential to start planning with a clear framework in mind.

“A lot of celebrations have become about the show and less about the meaning,” says Dr. Kate Luckins, author of Live More With Less. “Planning a sustainable wedding starts with prioritizing what’s important to you and shutting out the consumerist noise.” By establishing guiding principles early on, you can make informed decisions that align with your values.

Choose a Central Location and Keep the Guest List Small

Begin with your guest list and venue. Most wedding emissions stem from high guest counts and air travel. Limiting your guest list to close family and friends and selecting a location central to most of them can significantly reduce your carbon footprint.

Hosting both the ceremony and reception at the same venue can also help. This eliminates the emissions associated with transportation between locations. Michelle Miles, founder of the Sustainable Wedding Alliance, suggests providing a shuttle bus for guests traveling from further away. This not only reduces the number of individual cars on the road but also fosters a more social atmosphere.

When selecting a venue, look for one that aligns with your sustainability values. For example, Flowerdale Estate in Strath Creek, Victoria, operates primarily on solar power and features a garden that minimizes the need for extensive decorations. “Choosing a venue that is naturally beautiful means you don’t have to dress it up as much,” says Demmi Kerr, the venue’s wedding and events coordinator. They also have recycling programs and feed leftover food to rescued animals on the property.

Serve Food with Sustainable Ingredients

The menu is another area where you can make impactful choices. Meat-heavy dishes, imported ingredients, and over-catering can all harm the environment. However, food can also be a powerful tool for positive change.

“The gold standard for a sustainable menu is one that is seasonal, local, and plant-forward,” Miles explains. If a fully vegan wedding isn’t feasible, aim for a 70/30 plant-to-meat ratio to significantly lower the carbon intensity of your meal while celebrating local produce.

Consider hiring a caterer who sources ingredients from regenerative farmers. This approach supports a food system that actively pulls carbon from the atmosphere and restores soil health. To avoid over-catering, opt for sit-down meals or grazing plates instead of sprawling buffets. If you have leftovers, plan to offer them to guests to take home.

When it comes to beverages, choose local vineyards, brewers, and distillers. Australia boasts world-class organic and biodynamic options, which can help eliminate the carbon costs associated with shipping. For an even more sustainable choice, consider keg-to-tap options for wine and beer to eliminate single-use packaging.

Sustainable Decorations: Less is More

The most sustainable decorations are those that already exist. Prioritize hiring over buying or insist on second-hand items that can be reused, like vases or pot plants that guests can take home as wedding favors. Instead of printing individual menus, minimize waste by having just one shared menu on each table.

Miles advocates for a firm no to traditional wedding plastics like balloons and cheap synthetic favors. “If an item cannot be composted, recycled, or kept for a lifetime, why should it have a place on your table?” she asks.

When it comes to flowers, the mantra is “grown, not flown.” About half of fresh flowers sold in Australia are imported and often treated with heavy chemicals. Work with a florist who sources seasonal, locally grown blooms, and arrange for leftover flowers to be taken home by guests or donated to social services.

Beyond the One-Off Wedding Dress

Fashion’s environmental impact is significant, particularly when it comes to synthetic materials and garments worn only once. Opt for natural materials like wool, cotton, and silk for your wedding party’s outfits. Avoid buying items that no one will wear again. Circular models like rental and resale are also excellent options.

For wedding dresses, consider investing in a piece that can be worn more than once. Dresses made from natural materials are easier to overdye, making them more versatile. Rental options for women are becoming increasingly accessible, with platforms like The Volte and Glam Corner offering a range of bridal and bridesmaid outfits. Resale options are also available, allowing you to buy vintage dresses or sell your own after the big day.

If you want everyone in matching outfits, consider loosening the traditional expectations. “Do you have to have bridesmaids? Do they have to have matching dresses?” Luckins suggests. “Steer clear of Pinterest and try finding your own way. It can be really liberating.”

By focusing on these key areas—guest lists, venues, menus, decorations, and attire—you can create a wedding that celebrates love while minimizing its impact on the planet. Each choice you make can contribute to a more sustainable future, allowing you to cherish not just your special day, but the world around you as well.
