How is this calculated?
Running an event can impact the environment in multiple ways. In calculating your footprint for offsets, Cool Effect takes these factors into consideration.
Pounds per person
This calculator uses 400 pounds per person per day to calculate the base emissions of an event. Source: MeetGreen. The calculator converts to metric tonnes and uses our average price per tonne to create the price of the offset.
This assumes power usage for the space is provided by standard utilities. If your power is renewable, it will be less. If your power is a generator, it will be more. Contact us for help.
Cool Effect recommends that the travel footprint of any hosted speakers or special contracts/employees should be included. Cool Effect believes that travel emissions of attendees should be their responsibility. Contact us if you would like tools to encourage them to offset their own travel.
