Simplified Framework Cuts Environmental Impact Assessment Time
A new study by the Paul Scherrer Institute PSI reduces four hybrid methods to two, making it easier to assess the environmental impacts of products and services
A simplified framework could make it easier to assess the environmental impacts of products by reducing four established hybrid methods to two, according to a study by the Paul Scherrer Institute PSI. This breakthrough could enable life cycle assessments even without in-depth mathematical knowledge through open-source software.
The study, conducted by Michael Weinold and Guillaume Majeau-Bettez, aimed to address the problem of conventional life cycle assessments not capturing all processes that contribute to a product's environmental impact. Life cycle assessment is a mathematical method used to quantify the environmental impact of products and services, and it forms an important basis for political decisions.
The researchers published their findings in two studies in the Journal of Industrial Ecology, demonstrating that the four established hybrid methods can be mathematically reduced to two. This reduction could make it easier for companies and individuals to assess the environmental impacts of their products and services.
The goal of the study is to enable life cycle assessments to be conducted even without in-depth mathematical knowledge. To achieve this, the researchers provide recommendations on which method should be used and when. Life cycle assessment is only as good as the data it is based on, and the simplified framework could make it more accessible to a wider range of users.
## Why it matters The simplified framework could have significant implications for companies and individuals looking to reduce their environmental impact. By making it easier to assess the environmental impacts of products and services, the framework could inform political decisions and help to reduce the environmental footprint of industries. The study's findings could also contribute to the development of open-source software that enables life cycle assessments to be conducted without specialized mathematical knowledge.
The study's authors, Michael Weinold and Guillaume Majeau-Bettez, are experts in life cycle assessment and have conducted extensive research in the field. Weinold, who now works at ETH Zurich, carried out the research at PSI's Laboratory for Energy Systems Analysis, while Majeau-Bettez is a professor at the CIRAIG Life Cycle Assessment Research Center in Canada.
