Calculating a carbon intensity value for electricity is a complex process, requiring many decisions and trade-offs to be made, including allocation methods, system boundaries, temporal resolution and how to treat electricity demand for vehicle charging.
Carbon displacement factors vary in a wide range depending on the substituted good, system boundaries, allocation of energy consumption between the by-products of the life cycles, and whether the waste wood is reused for energy after demolition of the building.
Notably, the discovered correlated datasets are in line with the underlying primary system technology channel allocation with some boundary overlaps due to adjacent channel power leakages.
This range of values resulted due to differences in methodology chosen, such as the exclusion of various stages from the life cycle boundaries and allocation methods.
Additionally, emission uncertainties occur when modelling GHG balances due to the choices which can be made regarding input data, parameters, counterfactuals or chosen methodology such as defining scope, goal, system boundaries and allocation method of the investigated supply chain [17, 31 33].
The definition of system boundaries, the allocation of impacts, and the choice of data sources are inherently subjective.
This was particularly evident in changes made to the definitions of the terms allocation, product system, system boundary and waste.
VNO BG does not have a maximum guaranteed data rate or high boundary for allocation of data rates.
The traditional media are toothless; opposition politicians have been hounded into bankruptcy by the fierce application of defamation laws inherited from Britain; voters have face the threat that, if they elect opposition candidates, their constituencies will suffer in the allocation of public funds; constituency boundaries have been manipulated by the government.
The results from energy and GHG calculations are highly dependent on conditions such as system boundaries, system design, allocation methods and selected indicators.
