What can you do?

While weddings are a joyous celebration of love, they can also generate a surprising amount of carbon emissions. From guest travel and venue energy use to catering and décor, many aspects contribute to your wedding’s environmental footprint.

Measuring your carbon footprint with our calculator is the first step towards a more sustainable celebration. By understanding the impact of your choices, you can make informed decisions to reduce emissions and minimise your wedding’s environmental impact.

Every small step, from choosing local flowers arranged using sustainable practices to opting for a locally sourced drinks menu, adds up to a significant difference.

Remember, a sustainable wedding isn’t just about the environment – it can also be a more meaningful and memorable experience for you and your guests. Celebrating your love story with a commitment to the planet sets a beautiful tone and allows you to share your values with the world.

How was the calculator developed?

The wedding carbon footprint calculator was a project managed by the Sustainable Wedding Alliance. The data was gathered by Carbon Footprint and the calculator built as a web based app by the super talented team at Wholegrain Digital.

We will be updating the data frequently when the Greenhouse Gas emissions data is updated and as more event industry specific data becomes available. We have also commissioned some more detailed calculations of some of the wedding elements, which will allow us to increase the accuracy of the overall result.
