2019:Carbon offsetting
To reduce the environmental footprint of the conference, Wikimedia Sverige and the Wikimedia Foundation have decided to pay for carbon offsetting. The pollution caused by an event is part of the hidden costs and we want to ensure that we take responsibility for it.
The carbon offsetting is done with the support from Terrapass using the following techniques:
- Farm power
- Landfill gas capture
- Clean energy from wind power
- Improved forest management
