As a raw material for clean energy supply for the new generation, the soybean is conducive to the realization of global energy transition and sustainable development in the context of "carbon neutrality". However, global warming has been affecting soybean yields in recent years. How to clarify the correlation between meteorological factors and soybean yields, so as to ensure the security of soybean growth and development and the stability of renewable energy development, is a key concern of the government and academia. Based on the data of temperature, precipitation, sunshine duration and active accumulated temperature during the soybean growing season in Hulunbuir, Inner Mongolia Autonomous Region from 1951 to 2019, and soybean yield data of the city from 1985 to 2019, this paper adopted statistical methods such as the Trend Analysis Method, the Rescaled Range Analysis Method and so on to analyze the trends of yield changes, characteristics of abrupt changes and periodic patterns of climate factors and soybean yields in Hulunbuir. A Pearson Correlation Analysis and a Grey Relation Analysis were used to explore the correlation between climatic factors and soybean yields, followed by a comprehensive impact model of the combined effect of temperature and precipitation on soybean yields established by the Method of Integral Regression. The results showed that temperature and active accumulated temperature are the dominant factors affecting soybean yields in Hulunbuir, while the decrease in precipitation is unfavorable to the improvement of soybean yields. Meanwhile, temperature and precipitation have different effects on the growth and development of the soybean at different stages. The conclusion of this paper is of great practical significance for Hulunbuir to promote the sustainable development of clean energy. [ABSTRACT FROM AUTHOR]

To achieve the goal of 'Net-zero Europe' by 2050, the European Union (EU) has set up detailed policies in the fields of energy and climate. This paper summarizes the main characteristics of relevant policies in the EU and UK and their implications for China by reviewing these policies in the achievement of the carbon neutrality goal and other goals in the energy and climate fields. The characteristics of these energy and climate policies include: ① Top-down and bottom-up approaches are adopted to distribute the EU' s overall emission reduction targets to member states in accordance with the principle of fairness, and each member state formulates and adjusts its own goals to ensure the realization of the overall goals. ② Detailed transition plans are formulated for the power, industry, transportation, and building sectors; importance is attached to the application of new and renewable energy technologies such as solar, wind, and hydrogen energy; specific goals are set concerning coal power transition, nuclear energy development, energy efficiency improvement, carbon capture and storage, electrification, and building renovations; and the importance of energy security in transition planning is stressed. ③ A sound and mature emissions trading system and a fair transition mechanism are established to support the realization of the transition goals, and developing countries are helped to reduce emissions through technical dialogues and climate financing. To reach peak carbon emissions and achieve carbon neutrality, China should develop relevant roadmaps at national, sectoral, and provincial levels and strengthen R&D of key decarbonization technologies. At the same time, China should enhance its regulatory regime, and improve the carbon emissions trading system, the green financial system, and the just transition mechanism. [ABSTRACT FROM AUTHOR]
