Climatic change presents a health and economic threat and must be discussed comprehensively, in order to make sure the environment is preserved for future generations.

As Haifeng Deng and Paolo Davide Farah have already beautifully illustrated in their article "China's energy policies and strategies for climate change and energy security", the question of energy security is not entirely unrelated to climate change. Energy plays an important role in global warming. With our high energy consumption and the use of fossil fuels, energy has a major impact on the climate. Burning fossil fuels to generate electricity and heat releases large amounts of greenhouse gases, which accelerate climate change. In addition, toxic pollutants are released into the environment. The changing environmental conditions caused by climate change, however, also ensure that our energy requirements shift and/or increase. It is therefore obvious that renewable energies will play a more important role in energy generation in the future. Politics and the economy must adapt accordingly and develop concepts that will continue to ensure a comprehensive supply of energy and heat in the future. Climatic change presents a health and economic threat and must be discussed comprehensively, in order to make sure the environment is preserved for future generations. A detailed description of the problems can also be found in the article by Deng and Farah. In their article they explicitly deal with energy security in the Chinese context. This is relevant as China is one of the main emitters of CO2 but will also be one of the main victims of climate change. China is one of the largest investors in renewable energy. In 2017 its share was 45% worldwide. They are the largest producer of wind turbines, solar modules, and electric vehicles. As an economic power China needs a lot of energy and with the advancing growth and changing conditions due to climate change, they will need much more in the future. An offensive energy tactic is therefore urgently needed for China. As Deng and Farah show, also in the context of BRI. Within this framework, the energy market is to be opened up, thereby expanding energy trading. The plan is to diversify energy sources to central Asian, Russian, southeast Asian sources. China plans to expand its economic position and to be a pioneer and dominant player across the entire value chain of green energy and other ecological technologies. This is particularly evident in the field of photovoltaic systems. In the beginning, European companies were the leaders, but soon after China took over. In the meantime, European companies can hardly keep up. State subsidies in China are far too high in comparison. It is obvious that China wants to dominate the promising energy and ecology industries. Deng and Farah show how China wants to achieve this goal in their article: They show how China's energy policy is moving in an ecological direction and how this is reflected in the legal context. Not without addressing the problems of the Chinese energy environment. In all of this, one must not forget that despite all its efforts, China is also promoting and implementing non-ecological technologies. China is still the largest coal producer in the world.
