Life Cycle Assessment (LCA) is a methodology used to evaluate the environmental impact of a product, service or system throughout its life cycle, from its creation until its elimination. The main objective of the LCA is to assess environmental impacts through different life cycle stages, including raw material extraction, production, use, transport and disposal.
The LCA considers different environmental impact categories such as the use of natural resources, air emissions, water and soil pollution, the greenhouse effect and energy consumption. These impacts are measured and evaluated using category-specific indicators to assess the environmental impact of the product or system analysed.
According to a study carried out by the environmental engineering department of the Politecnico di Milano, the LCA of Limenet, depending on the “carbon footprint” of the electricity used is between 5-10%.
This means that, that Limenet removes 100 kg of gross CO₂, it is emitting 5-10 kg. As a result the net CO₂ removed is 95-90 kg.
