Saving energy, reducing emission and dealing with climate changes are global objectives. The aviation industry belongs to the manufacturing industry. Air transportation is a major con- sumer of natural resources and energy. Development of green technology in aviation manufacturing will have sig- nificant impacts on air transportation. On the basis of the international situation, this article focuses on the current development of green aviation manufacturing in China, depicting AVIC＇ s objectives and commitments to achieving this.展开更多

The characterization methodology of asphalt VOCs and theinfluencing factors on VOCs release have always been the basic issue of asphalt VOCs emission reduction research.Researchers have proposed a variety of asphalt VOCs characterization methodologies, which also have mutuallyirreplaceable characteristics. Asphalt VOCs volatilization is affected by many factors. In this study, asphalt VOCscharacterization methodologies were summarized, including their advantages, disadvantages, characteristics andapplicable requirements. Subsequently, the influencing factors of VOCs release, such as asphalt types and environment conditions, are summarized to provide theoretical support for the emission reduction research. Theclassification and mechanism of newly-development asphalt VOCs emission reduction materials are reviewed. Thereduction efficiencies are also compared to select better materials and put forward the improvement objective ofnew materials and new processes. In addition, the prospects about development of VOCs release mechanism ofasphalt materials during the full life cycle and feasibility research of high-efficiency composite emission reductionmaterials in the future were put forward.展开更多

Green development will greatly help China choose its path for economic growth. In the newly ratified Paris Agreement, the carbon emission reduction target willingly and determinedly proposed by China is very challenging. It will increase China's cost per unit of carbon dioxide emissions, slow China's economy growth, and set the upper limit for China's carbon emissions in the future. Facing these challenges, China needs to properly conduct carbon allocations under restrictions and promote green and low carbon development of the Chinese economy primarily by reinforcing structural adjustments and optimizing energy structures, upgrading industrial structures, being actively involved in international cooperation on carbon emission reduction and using other positive strategies.展开更多
文摘With rapid economic progress and tremendous advances of science and technology, awareness of environmental protection has become worldwide consensus. Saving energy, reducing emission and dealing with climate changes are global objectives. The aviation industry belongs to the manufacturing industry.
