Life Cycle Assessment (LCA) - Per 1 tonne (T) :
-
Based on Ecoinvent database (from raw material extraction to the end of the production process)
​
-
Carbon footprint = ∿ 4670 kg CO2 eq / T , which is approximately equal to (US EPA data):
-
∿ 18870 km travel (car) ​
-
∿ consuming 1980 liters of petrol
-
∿ burning 2340 kg of black coal
-
∿ 6 month-long energy consumption of an average European household ​​
-
∿ burning 11 barrels of oil
-
​
Carbon neutralization of this quantity would require at least:
-
∿ Development of 77 seedlings over 10 years ​
-
∿ One-year-long carbon sequestration capacity of 2.3 hectares forest
