Quick answer
Add up guest travel (guests × distance × a factor for each mode), hotel stays (room-nights × 58.9 kg CO₂e for India), venue electricity and generator diesel. Guest travel is usually the largest part, especially when guests fly.
Food, decor, clothes and gifts are not included because their footprints vary too widely to estimate from a few numbers.
Plant a wedding forest with a tree for each guest, or gift trees as return gifts. Each tree is a 2-3 ft sapling, cared for three years, geo-tagged and comes with a certificate.
Usually guest travel, especially flights. A destination wedding with many flying guests can be several times larger than a local one.
At 58.9 kg CO₂e per room-night, the UK government's 2025 average for hotel stays in India. Enter rooms × nights.
Menus and sourcing vary too much to estimate reliably from a few inputs, so the calculator focuses on travel, stays and power.
The calculator shows the trees whose yearly uptake, once mature, matches your total, allowing for 85% survival across our programmes. Many couples plant one tree per guest.
Yes. Gifted trees come with a certificate, and guests can see them on a digital forest page.
