Air transport is increasingly becoming more accessible to a greater number of people. The sector forecasts that over the next decade, both passenger and freight traffic is expected to increase at an average 4-5% p.a., both significantly above global GDP growth. In air transport terms, this implies a doubling of traffic about every 16 years. It is evident that environmental requirements, such as noise impact and emissions, will play a dominant role in future transport aircraft development, becoming a driving force for aircraft design. The adoption of this kind of global requirement has two main consequences: firstly, the greening level becomes one of the criteria for which a new aircraft has to be judged or selected; and secondly, the aircraft configuration itself must be defined to fulfil the greening requirements. The direct greening design criteria are represented by halving perceived aircraft noise and a reduction in CO2 emissions. The indirect greening requirements must also be considered, for instance, drag reduction and weight savings.

许多人越来越多地使用航空运输。该行业预测，在未来十年中，预计乘客和货运流量的平均为4-5％，均显着高于全球GDP增长。在航空运输方面，这意味着大约每16年的交通量增加了一倍。显然，环境要求（例如噪声影响和排放）将在未来的运输飞机开发中起主要作用，成为飞机设计的推动力。这种全球要求的采用有两个主要后果：首先，绿色水平成为必须判断或选择新飞机的标准之一；其次，必须定义飞机配置本身以满足绿色要求。直接的绿色设计标准以减少感知的飞机噪声和二氧化碳排放量减少来表示。 还必须考虑间接绿色要求，例如减少阻力和节省重量。
