The net zero emission target of Taiwan
 In 2022, the Government of Taiwan announced the net zero target

Clean electricity supply is essential to achieve the target
 Energy sector contributes 71% of greenhouse gas (GHG) emissions: Around

50% of total emissions come from electricity
 The decarbonization of electricity can speed up the zero-target

The budget and project plans by 2030
 Total budget of 30 billion USD by 2030: 15 billions of new fundings areprovided by state-owned companies while 11 billions are offered by government
 By project fields: Power supply are major (renewables and power system) are major(48%) of budget. Green transport (19%) and energy saving (14%) follow

Previous target for 2050
 Limitations:

Evaluated by Taiwan TIMES model (ITRI)

 No adjustment of electricityprice No adjustment of industrial
activities No reveal the carbon priceinformation

 2050 power supply mix
 Renewables 60-70%
 Hydrogen: 9-12%
 Gas+CCUS: 20-27%
 Emissions reductions inother sectors

 Industry: 8.7 million tonne (Mt) Transport: 3.3 Mt
 Non-Energy use: 10.5 Mt.

Economy mainly drives electricity demand Taiwan’s GDP growth closely relates to electricity demand growth: thecorrelation coefficient from 2005 to 2022 is 0.92
 We must consider the interaction between economy and energy through anintegrated model

 Integrate the power supply model of Dr. Ashina and AIM/CGE for Taiwan
 Revisit the net-zero emission pathway of Taiwan

11Conclusions and future plans Taiwan must commit to the net-zero target

 The new office, T-STONE, is making progresses for the design of zeroemission pathway A hybrid model (Power supply and CGE) will evaluate the new net-zero
pathway for Taiwan
