In this article


When to use

Required Required for products that require certain information to be shown in your Shopping ads or free listings, for example due to local energy efficiency labeling regulations.

Optional Optional for all other products

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 example:

  • Fridges and freezers
  • Dishwashers
  • Televisions and other external monitors
  • Household washing machines and washer-dryers
  • Refrigerating appliances with a direct-sales function
  • Light sources

You may be required to show the EU energy efficiency class on your Shopping ads and free listings. You can do so by providing the certification [certification] attribute in your product data for applicable products. Google will look up your product in the EU EPREL database and render the appropriate energy efficiency class in graphical or textual form on your Shopping ads and free listings. For example:

An icon depicting energy efficiency class rating.

Note: If you aren't able to locate your product’s EPREL code and have energy efficiency information only in the form of the rating itself, you can provide all 3 energy efficiency class [energy_efficiency_class] attributes until the end of the transition ending on September 1, 2024.

Sub-Attributes

This attribute uses the following sub-attributes:

  • Authority [certification_authority](Required): The authority or certification body responsible for issuing the certification. At this time, we only support the values "EC" or “European_Commission”.
  • Name [certification_name] (Required): The name of the certification. At this time, we only support the value "EPREL", which represents energy efficiency certifications in the EU European Registry for Energy Labeling (EPREL) database.
  • Code [certification_code] (Required): The code of the certification. For example, for the EPREL certificate with the link https://eprel.ec.europa.eu/screen/product/dishwashers2019/123456 the code is 123456.
