MICE is still moving a lot of carbon through travel and venue power, but the direction is getting clearer as 2023 data reveals bigger wins than many event teams expect. Hybrid formats cut emissions by 64 percent and virtual reality meetings can reduce emissions by 90 percent compared with physical gatherings. Meanwhile, the less obvious drivers like accommodation and daily venue energy keep showing up in the totals, which is why the dataset is worth looking at side by side.
Key Takeaways

- Air travel accounted for 78% of the carbon footprint in MICE events in 2021, with an average of 0.45 tons CO2 per attendee for flights over 1000km
- Hybrid events in 2023 reduced carbon emissions by 64% compared to in-person equivalents, saving an estimated 250 kg CO2 per virtual participant
