In order to take care of the environment the organization of Marbella 4Days Walking has decided to make the event a CO2 neutral one. This means that all CO2 generated by the organization of this event will be compensated by planting trees.
After the event is finished a study will be done in order to determinate the amount of the CO2 emission caused by the use of electricity, paper and travels. Knowing this, it will be possible to know the quantity of trees necessary to provide enough oxygen to create a neutral balance.
These trees will be donated and planted by Arboretum Marbella . They have special plantations for autochthonous trees within the municipal limits of Marbella. Arboretum Marbella uses these plantations to maintain original nature and for educational purposes.
