Wedding carbon footprint calculator

Calculating the carbon footprint of a wedding is straightforward. You just need to know the number of guests and the rough details of their travel plans.

Enter the details below.

What's included in my wedding's carbon footprint?

The wedding calculator takes into account four different sources of emissions:

• Airline emissions from guest travel.

  For most weddings, this is by far the most important category of emissions. Planes burn a lot of fuel, and these days most weddings bring together people from all over the country and the world.

• Automobile emissions from guest travel.

  Cars aren't likely to be a huge source of greenhouse gas emissions for your wedding, but if you have a lot of local guests, they will collectively burn a modest amount of gasoline getting to the event.

• Energy use in hotel rooms.

  Hot showers, lighting, and air conditioning all require electricity. For large weddings, this energy use can add up.

• Energy use for the wedding itself.

  The DJ, the caterer, temperature control, lighting – whether you have your wedding on the beach or in a banquet hall, the event itself requires some energy. Truth be told, the amount of emissions from the event itself is small – about one ton of CO₂ or less – so we just add a little to the total to cover it.
