Life cycle considerations

Performance analysis is not only extremely important in determining overall performance of the cycle but in also determining life cycle considerations of various critical hot section components.

The above implies that the narrowly understood ecological labels are (1) voluntary, (2) show the environmental impacts of a product to the consumer and (3) are preferably based on life cycle considerations and are verified by a third party (governmental and nongovernmental organisations). Because of these characteristics, they can be viewed as a subgroup of a wider category of environmental labels. 

The risk of misleading labels being used can be minimised by giving stronger emphasis to labels verified by a third party based on multiple criteria and life cycle considerations. The effectiveness of an environmental label as a countermeasure against greenwashing practices and a way to gain consumer trust depends on its ability to be truthful, easy to communicate and, finally, verifiable and accurate.

Resource and environmental profile analysis (REPA), the forerunner to the current practice of life cycle assessment, focused on quantifying the energy requirements and emissions of a product or process but not the impacts on human health or the ecosystem. Ideally, according to the originators of REPA, the analysis would be linked to a risk assessment of emissions related to a process or product [91,92]. It is worth noting, with respect to the theme of this book, that REPA originated in 1969. Environmental life cycle considerations did not formally enter into product development or modification before that time.
