Financial transfers
Besides emission trading, another mechanism to redistribute costs among regions is by allowing financial transfers to compensate for damage costs. In MIMOSA, two types can be chosen: either no financial transfers (default), or a global damage cost pool.
The financial transfer module can be chosen using the parameter financialtransfer module
.
Note that the difference with emission trading is that (paid for) emission reductions are not affected by any financial transfer from this module.
Usage:
params = load_params()
params["model"]["financialtransfer module"] = "notransfer"
model = MIMOSA(params)
Without financial transfers, this variable is always equal to zero:
Source code in mimosa/components/financialtransfer/notransfer.py
Usage:
params = load_params()
params["model"]["financialtransfer module"] = "globaldamagepool"
model = MIMOSA(params)
When allowing financial transfers for a global damage cost pool, a region can receive financial transfers up to its level of climate damages:
The sum of financial transfers per time period should be zero, since it is a redistribution of costs:
Also, in the first year, no financial transfers are allowed:
Finally, the financial transfers are expressed in currency units (dollars). They can also be expressed as percentage of GDP:
