In recent years，in order to achieve the goals of the Paris Agreement，the EU is accelerating the transition to a low-carbon economy，with annual spending on energy production and supply equipment increasing year by year，especially in the field of renewable energy power generation，which has become a key force in promoting low-carbon transformation. However，compared with the actual needs of international development，there is still a big gap between the EU in terms of energy security and supply stability，low-carbon investment，technological innovation and R&D capabilities. In order to better stimulate the R&D and application of low-carbon technologies，empower the EU to accelerate the transition to a low-carbon economy，and provide reference and inspiration for the development of related fields at home and abroad，this report puts forward the following countermeasures and suggestions：further improve and refine relevant regulations，and provide more policy support and incentives for the R&D，application and promotion of low-carbon technologies to ensure the compliance of technologies and the orderliness of the market；By promoting the comprehensive transformation of the energy system，including electricity，transportation，buildings and other fields，to promote renewable energy technologies such as solar and wind energy will occupy an increasingly important position in the EU energy system；Provide more economic incentives for the development of low-carbon technologies through the tightening of climate policies and the continuous improvement of the carbon market，and the optimization of the allocation and trading mechanism of carbon allowances；By continuing to increase R&D investment in the field of low-carbon technologies，we will promote breakthroughs and applications in key technologies，strengthen cooperation and exchanges with other countries and regions in the field of low-carbon technologies，and jointly promote the development of global low-carbon technologies.
