You, as a future FUNNYCAMPS participant, will emit a carbon footprint to the atmosphere by taking a flight from your country to Spain. That action will provoke a lot of greenhouse gases due to the pollution of a flight.
Have a look at this example:
Carbon footprint of a participant in a return flight from Montreal to Spain =786.2 Kg de CO2
Carbon footprint in a return flight from London to Spain =263.6 Kg de CO2
