The Paris Agreement passed at the United Nations Climate Summit in 2015 hopes to rely on the efforts of all countries to curb the runaway trend of global warming. The target global greenhouse gas emissions must reach net zero by 2050. Through the formulation of policies and laws, all countries will achieve net zero emissions by 2050. Discussing the goal of net zero carbon emissions and the transition path involves the country's long-term carbon reduction project. Policies include issues such as national energy ratio, industrial green transformation, future economic and social development vision, and the introduction of new technologies. It needs a series of research based on scientific foundation. In addition, dealing with the complexity of economic development and energy demand and greenhouse gas emissions, it’s necessary to rely on the integrated analysis of different models and the integrity assessment of future scenarios to provide policy support. Therefore, this research takes Taiwan‘s 2050 net zero emission target as the main topic, using the general equilibrium model and the corresponding database. Combined economic and trade development, and establishes general equilibrium model for Taiwan. In oreder to calculate the BAU(Business as Usual) scenario for 2050. Moreover, construct a diversified context for carbon reduction, and evaluate the corresponding economic impact and policy path. Due to greenhouse gas emission reduction involves other energy engineering models and economic development models, it’s necessary to integrate the different models, as well as the future development scenarios of Taiwan. Estimate the energy demand path of the whole and major sectors, and analysis with international long-term carbon reduction integration models. Combining the economic model and energy engineering model of my country’s important greenhouse gases to link key sector parameters and carbon reduction scenarios, and establish an integrated analysis framework for the long-term carbon reduction path of my country’s greenhouse gases; however, the integration of economic and energy models still needs relevant think tanks and The collaboration and discussion of the ministerial committees must be continuously promoted. The economic and industrial development path estimated by the front-end economic model will be first carried out, and the energy-related information of various departments will be used to evaluate the energy demand path through data analysis. The follow-up can assist the Environmental Protection Agency(EPA). To assist the government to set up Taiwan’s pathway toward Net-zero GHG emissions, this research comprehensively analyzes the actual progress of the European Union, the United Kingdom, Japan and South Korea's net zero emissions and analyze the results. With the establishment of the net zero carbon emission target, the demand for funds will also increase. In order to facilitate subsequent planning and start related net zero emissions related work, it is necessary to review and invest in major public construction design. This research assists the PEA in organizing the future resource needs of relevant departments and develop the “Medium and Long-term Projects”. It also assists the EPA in strengthening the assessment of the net-zero emission path and preliminary blueprint planning, including: designing the economic tool supporting mechanism for the net-zero scenario, compiling the "net-zero emission path medium and long-range case plan", and researching and analyzing the "net-zero emission path" The relevance of the “Long-term Case Project” to my country’s policies such as the “Phase II Control Targets” and the “Net Zero Path”.
