The update to EN 15804+A2 has changed the impact indicators that are reported in EPDs. An EPD done to EN 15804+A1 will not report these required impact indicators. If your LCA is being done to the new standard, +A1 EPDs can be used in conjunction with a +A2 compliant datapoint using our "Use for A1/A2/TRACI" feature.
The below screenshot is a practical example of this, where an Ecoinvent datapoint is used for +A2 impact categories, while an EPD is used for +A1 results:
The warning symbol beside the EPD is to draw attention for you to check which impact indicators it is compliant with. All Ecoinvent data is compliant with +A1, +A2 and TRACI impact indicators.
