FOOTPRINT CALCULATION

Sources for calculating CO2 emissions:
- National Atmospheric Emissions Inventory (United Kingdom)
- Department for Environment, Food and Rural Affairs (United Kingdom)
- "The eco-efficiency of tourism" (article)
- Food-related CO2 meter, developed by WWF (http://www.improntawwf.it/carrello/)

Source for calculating the water footprint of food:
- Publication "Water Economy" by Barilla Center for Food and Nutrition (https://www.barillacfn.com/m/publications/pp-watereconomy-it.pdf)

Sources for calculating the needed amount of trees for absorpiton:
- degree thesis on the study of the environmental impact of the university complex Legnaro PD-Polo Agripolis edited by Elisa Negrini, Supervisor prof. Davide Pettenella, University of Padova
- Provincial energy plan of the Provincia Autonoma di Trento, 2013-2020
- Servizio Foreste Provincia Autonoma di Trento, referente dott. Marcello Scutari
- AA.VV., IPCC Guidelines for National Greenhouse Gas Inventories Agriculture, Forestry and Other Land Use
- web site treedom.net, with an environmental calculator edited by IPCC (Intergovernmental Panel On Climate Change)

Total CO2 kg emitted for transfers: 2697 (65%)
Total CO2 kg emitted for accommodation: 233 (6%)
Total CO2 kg emitted for food: 1204 (29%)
Total for the whole group of 7 people: about4134 CO2 kilograms (rounded to 4 tonnes)

Total water consumption from food consumed and showers taken (by the whole group): about 502943 litres of water, equivalent to 3353 bath tubs, that put in a row would cover a distance of 6 km!
This amount of water could be used to water about 2012square meters of vegetable garden for a whole year (250 l/sqm/year), that in our area could give nourishment to 20 families (100sqm/family). Alternatively, this amount of water could quench a dairy cow's thirst for 2515 days (about 200 l/day).

How can we balance these emissions?
Estimating that it takes about 100 trees to absorb one tonne of CO2 in a year, the emissions from the class trip 6 to Germany can be balanced by 413 trees.

These trees correspond to approximately 3717square metres of forest (corresponding to 0.44 football fields) which can be enhanced as follows:
- you can support the Otonga project in Ecuador with a donation of ?557.55 (?0.15 each sqm) to buy a corresponding area of forest;
- you can set aside time for an environmental protection activity in your school, to be agreed with your class teachers;
- you can carry out an activity, planned with your family or firends, on environmental sustainability. Remember to communicate this to your class teachers.
