This update concerns the EU and EFTA countries as well as the UK.
What is changing
 In 2023, Google introduced the "certification" attribute to describe certifications, including energy efficiency ratings, and to comply with updated EU energy labeling regulations.
Since this new attribute overlaps with the existing "energy_efficiency_class attributes", Google will be phasing out the "energy_efficiency_class" attributes in favor of the "certification" attribute.
This update is required for products that require certain information to be shown in your Shopping ads or free listings, for example due to local energy efficiency or emissions related labeling regulations. If your products target any of the EU or EFTA member states or the UK, consult EU energy efficiency regulations or any applicable local law to determine if you need to provide this attribute. This includes products covered by rescaled EU energy labels.
For further details on this check the original communication from Google Merchant Center.
