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.

Germany's energy transition （Energiewende） is a paradigm shift into a low-carbon and nuclear-free economy. As part of the European Union's climate neutralization drive, aiming to reduce greenhouse gases to net-zero by the middle of the century. Generous financial support for wind and solar power has boosted renewable energy to produce more electricity than fossil fuels for the first time in 2020. Germany's energy transition is not a policy shift after the Fukushima nuclear disaster, but a long-term process of policy making in response to public opinion and technological trends. Germany's energy transition is still underway and needs to be extended beyond the power supply. However, it may already be pushing more thoroughly through pricing and volume regulations, such as the European Emissions Trading Scheme （EU-ETS） and changes to the carbon tax, which provides incentives for changes to low-carbon technologies. This paper analyses Germany's energy transition and climate policy. The purpose of this paper is to clarify the actual conditions and issues of the reduction effects of greenhouse gas emissions, which are the main policy issues of the energy conversion policy that has been developed mainly on renewable energy for these 20 years.
