At Orthex, we have also conducted a study to analyse the carbon footprint of products. The study was prepared in accordance with the PAS 2050 standard, a widely used specification that provides a method for assessing the lifecycle greenhouse gas (GHG) emissions of goods and services, and result were verified by a third party independent expert (Gaia Consulting Oy).
The environmental performance of different products was evaluated using lifecycle assessment (LCA) methodology. Lifecycle assessment (LCA) is the guide to estimate carbon footprint of any product based on LCA-defined stages that are consecutive and interlinked. The LCA stages are raw material extraction, manufacturing, distribution, usage, and final disposal. Calculation was done for a comparative purpose where some of the stages are excluded. The reason for exclusion is that some of the stages contribute with exactly the same amount of emission, and hence does not impact the comparison. Excluded stages are raw material packaging, labelling, packaging, distribution, and the usage stage.
