To date, the process of implementing the global Sustainable Development Goals （SDGs） and global climate change mitigation and adaptation obligations has been largely decoupling in most countries. This creates administrative duplication, costs, and hinders the development of effective problem solving. Against this background, we show the present state of research on policy integration and integrated policymaking. Following the research results of Bauer et al. （2021） and Teebken et al. （2021）, this note briefly summarizes different understandings of policy integration and detailed criteria for evaluating policy integration from different　academic perspectives. Implementing an interactive agenda requires political　attention and institutional competence to address the interactions and complexity　of each, understand policies at a national level, and translation. In this note, we will　introduce the basic concept of what integration practice looks like, and focusing on　the interaction between the 2030 Agenda and the Paris Agreement.

Taiwan is not a party to the Paris Agreement, but the impact of climate change on Taiwan is enough to be one. The Government of Taiwan has set a target of adjusting the power mix to 50% natural gas-fired, 30% coal-fired and 20% renewable energy by 2025, increasing the proportion of relatively low carbon emissions and renewable energy, and aiming to reduce GHG emissions as a climate change policy. One of the key aspects of Taiwan’s energy policy is to phase-out nuclear power generation by 2025, and to increase the share of renewable energy in the power supply configuration and reduce the use of coal-fired power. The phase-out of nuclear power plants was initially faster than the expansion of renewable energy, reducing CO2 emissions from electricity production as needed to a small amount. Nevertheless, since 2016, Taiwan has been evaluating the “energy transition” derived from Germany and is trying to decentralize its power supply using conventional large-scale, inflexible power generation systems. 　With regard to coal-fired power plants, Taiwan will accelerate the improvement of air pollution facilities at existing coal-fired power plants and implement utilization management measures in order to match air quality. Gas-fired and green energy power supplies will be the mainstays of power supply, which is the power stabilization target, in order to maintain 15% of the supply reserve rate. The government needs to plan supply-side measures and implement various tasks to save energy and reduce carbon emission in order to reduce electricity demand. To build clean energy systems and healthy living conditions, to promote the development of new green energy industries, to promote green employment, realize the spirit of energy empowerment, promote energy democracy and justice. Going forward, the focus will be on overall system integration, where all power supplies can ensure a sufficient level of revenue. In this study, we will consider Taiwan’s climate change and energy policy since the Paris Agreement, and summarize the current situation and issues.

As climate change and various environmental pollution issues are becoming more serious, many countries are actively promoting energy transition. The Paris Agreement, adopted in 2015, is aimed at curbing the rise in global average temperatures to within 2℃ above pre-industrial levels and limiting temperature rises to 1.5℃ above pre-industrial levels. Taiwan is accelerating its path of energy transition to a "nuclear-free homeland" and “low-carbon economy” by phasing out all nuclear power generation in 2025 and imposing a legally binding goal of reducing coal-fired power generation from 47 percent to 26 percent. This paper investigates the impact of nuclear and coal power regulations on fuel mix CO2 emissions in the power sector by 2050 in Taiwan. Analysis is a future technology shift in the power sector called “Future Technology Transformations; FTT” for the power sector; Consider using the E3ME model linked to FTT: Power sub-model.
