Green Wedding Planning 101: A Guide to Saying "I Do" Sustainably

Planning a wedding is an exciting journey, but it can also have a significant environmental impact. From food waste to excessive decorations, traditional weddings can generate a surprising amount of waste. Fortunately, couples today have more options than ever to plan a beautiful, meaningful, and sustainable celebration. Whether you're just starting your wedding planning journey or looking for simple ways to make your big day greener, this guide will help you create a wedding that aligns with your values.

1. Choose an Eco-Friendly Venue

One of the biggest factors in wedding sustainability is the venue. Look for locations that prioritize sustainability, such as those with LEED certification, renewable energy sources, or comprehensive recycling and composting programs. Outdoor spaces, such as botanical gardens or nature preserves, can also minimize the need for excessive decorations and energy use. Take a look at the list of Green Wedding Alliance approved venues here.

2. Go Digital with Invitations

Consider ditching traditional paper invitations and opting for digital invites instead. If you love the feel of a physical invitation, choose recycled paper or seed paper that guests can plant after the wedding. Many eco-conscious stationery companies offer beautiful, sustainable options. When it comes to the other typical paper goods - like programs, menus, etc. - choose to either eliminate them or reduce the number to be less than one per person.

3. Embrace Sustainable Fashion

When it comes to wedding attire, there are several ways to make an eco-friendly choice:

• Shop second-hand or vintage wedding dresses.

• Rent attire instead of purchasing new.

• Choose designers who use ethical and sustainable materials.

• Encourage your wedding party to re-wear outfits they already own.

4. Choose a Sustainable Caterer

Food waste is a major issue at many weddings. Work with a caterer that sources locally, uses organic ingredients, and minimizes waste. Consider a plant-based or vegetarian menu, which has a lower environmental impact. Donating leftover food to local shelters is another great way to reduce waste. Check out our list of Green Wedding Alliance approved caterers here.

5. Choose Eco-Friendly Decor

Decorations are often single-use, but they don’t have to be! Opt for reusable or compostable decor, such as:

• Locally sourced flowers or potted plants that guests can take home. (Make sure to work with an eco-friendly florist!)

• Upcycled and thrifted decor. (Don’t miss the Green Wedding Alliance biannual Recyclery event!)

• LED or solar-powered lighting.

• Renting decor instead of purchasing new items. (Here are some sustainable vendors who offer decor rental.)

6. Reduce Waste with Conscious Planning

A zero-waste wedding may not be realistic for everyone, but you can take steps to significantly reduce waste:

• Offer compost and recycling stations.

• Avoid single-use plastics (use real dishes, cutlery, and cloth napkins).

• Choose biodegradable confetti or dried flower petals instead of traditional rice or plastic confetti.

7. Opt for Green Transportation

Encourage guests to carpool, provide shuttles, or choose a venue accessible by public transportation. If possible, consider renting electric or hybrid vehicles for wedding day transportation.

8. Give Thoughtful, Sustainable Favors

Skip wasteful trinkets and instead offer eco-friendly favors, such as:

• Small potted plants or seed packets.

• Locally made, organic treats (like Katherine Anne Confections or Keep it Savory Salt Co.)

• Donations to an environmental charity in honor of your guests.
