The Pacific Island countries, as one of the regions most affected by climate change globally, are particularly vulnerable to rising sea levels, storm surges, floods, and tsunamis, among other disasters. These challenges are compounded by the fact that their economies largely depend on fisheries and tourism, both of which are threatened by climate change and ocean acidification. At the 28th United Nations Climate Change Conference (COP28), significant progress was made on ocean issues in the first-ever Global Stocktake of the Paris Agreement. This milestone reflects an unprecedented recognition of the need to incorporate ocean considerations into climate action and to enhance ocean initiatives based on the best available marine science. At the same time, China has always attached great importance to the special difficulties and concerns faced by Pacific island countries in addressing climate change. At the general debate of the 75th United Nations General Assembly, Chinese President Xi Jinping solemnly announced that China will increase its national independent contribution, adopt more effective policies and measures, strive to peak carbon dioxide emissions before 2030, and try to achieve carbon neutrality before 2060. This is a solemn commitment made by China to address global climate issues. The first issue of Qiushi (CPC Central Committee Bimonthly) in 2024 published an important directive by President Xi on comprehensively promoting the modernization of harmonious coexistence between humanity and nature through the construction of a Beautiful China. On January 25th of this year, Premier Li Qiang of the State Council signed State Council Order No. 775, announcing the Interim Regulations on the Management of Carbon Emissions Trading, which will come into effect on May 1st. In accordance with the special administrative regulations formulated by the state, this regulation is of great significance for providing clear legal basis for the operation and management of the national carbon emissions trading market, ensuring and promoting its healthy development.【More】
