Guide to a Sustainable Wedding

Garden wedding

It is astonishing how much money is wasted at an average wedding and how much the CO2 emissions are. Then there is the usually vast amounts spent on a wedding dress and suit, only to be worn once. For example, the decorations’ cost (most of which will probably end up binned), the balloons released without a thought for the environment (a few seconds pleasure watching them drift off, potential death and littering for the environment and animals).

The more you look into the waste engendered at weddings, the more uncomfortable it makes one feel. But there is a way to feel comfortable, sustainable and still have a dream wedding! We recently came across a fab article by 77Diamonds with some great ideas. We have just highlighted a few below to whet your appetite for more info! Please follow the link at the end of the post to read their full, detailed article.

Waste generated by the wedding industry

On average, an astonishing £488 is wasted on food at a wedding. 15% of guests will not eat all 3 courses, and 15% of newlyweds throw away wedding cake leftovers.

Just think how much you could save with, eg, a buffet rather than a 3-course meal and a smaller wedding cake!

A Wedding’s carbon footprint

Up to 14.5 tonnes of CO2 is created at the average wedding celebration


We are always banging on about balloon releases – they are lethal to wildlife and the environment. They are quite literally nothing but litter. For more info see our ballon release blog here.


If you don’t use biodegradable confetti, such as petals, you are again littering and running the risk of animals eating the pieces.

Exotic flowers

Even your flowers can rack up the CO2 emissions if you are not using local flowers grown locally or in your own garden. Exotic flowers flown in from abroad increase your carbon footprint via airmiles and have probably been sprayed with pesticides.


Stop and think about what you are using – is it sustainable, recyclable or, even, necessary? For example, fabric bunting could be re-used at someone else’s wedding or in the home/garden/other events.

Choose an outdoor venue to make the most of summer daylight, or a venue that has outdoor space. Some venues are greener than others – check them out before booking. Even choosing a central location to all your guests will cut down mileage and carbon emissions from your guests getting to the venue.

Wedding rings

Research your jeweller and ask them if the diamonds are ethically sourced and not from conflict-zones.

We have barely touched on the many ways you can make your wedding more sustainable. Read the full, excellent article here, on 77 Diamonds website. If you have any ideas to add as to how you made or are making your wedding more sustainable, we would love to hear from you!
