What should you always check when using EPDs?

When using Environmental Product Declarations (EPDs), it is crucial to check the units used for reporting values. This is because EPDs provide standardized information about the environmental impact of products, and the measurements included may vary based on different factors, such as the type of environmental impact being assessed (e.g., carbon footprint, energy usage). Ensuring that you understand the units (whether they are in kilograms, liters, etc.) is essential for accurately interpreting and comparing data across different products. This understanding helps avoid miscalculations and incorrect assumptions about a product's environmental performance, ultimately guiding informed decision-making in sustainable practices.

The historical data of the product and the manufacturer's reputation can provide context, but they do not have the same immediate impact on understanding the specific environmental metrics presented in an EPD. Similarly, the color and style of the product are irrelevant to its environmental impact and do not contribute to the key analysis provided by EPDs. Focusing on the reporting units is fundamental to leveraging the information correctly and making informed choices.
