Short explanation

When interpreting life cycle assessment (LCA) data, it is essential to use mathematical concepts such as decimals, ratios, fractions, and percentages. These tools allow for a clearer understanding of resource use, energy consumption, and waste generation throughout a product's life cycle. Additionally, estimates and significant figures help ensure that the data is presented accurately and meaningfully. By applying these numerical skills, students can effectively analyze and compare the environmental impacts of different products, leading to informed decisions regarding resource management.
