When to use

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.

Optional for all other products

Note: Merchants in Germany are legally required to display the CO2 emission class for new vehicles. For Merchants in France, this is optional. Markets not mentioned here explicitly don’t require emissions class to be displayed.

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:

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 period 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 support the following values:
  • "EC" or “European_Commission” for energy labels in the EU
  • “ADEME” for the French CO2 emissions class for vehicles
  • “BMWK” for the German CO2 emissions classes for vehicles
• Name [certification_name] (Required): The name of the certification. At this time, we support the following values:
  • "EPREL", which represents energy efficiency certifications in the EU European Registry for Energy Labeling (EPREL) database.
  • “Vehicle_CO2_Class” for the overall CO2 class of a vehicle
  • “Vehicle_CO2_Class_Discharged_Battery” for the CO2 class of a vehicle with a discharged battery
• Code [certification_code] (Sometimes 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. The code is required for European Energy Labels. Not required for Vehicle ads.
• Value [certification_value](Sometimes Required): The value of the certification. This field is ignored for certifications that require a certification code, like EPREL, but can be provided for specific certifications where a code isn't applicable. Specifically, the value of the appropriate CO2 Emission Class is required when listing vehicles in some countries. For details, refer to the Vehicle ads overview.

Format

Follow these formatting guidelines to make sure Google understands the data you're submitting.

Learn when and how to submit your product data in English

Type	Unicode characters (Recommended: ASCII only)
Repeated field	Yes

File format	Example entry
Text feeds	Format the attribute header by including the sub-attributes you’re submitting. Include certification [certification], and then, in parentheses, add the names of the sub-attributes that you want to submit separated by a colon ( : ). Don't use quotation marks. The authority [certification_authority] and name [certification_name] sub attributes are always required. For example, to submit 3 sub-attributes authority [certification_authority], name [certification_name], and code [certification_code], submit the attribute header: certification(certification_authority:certification_name:certification_code) Example header and values: For EPREL: certification(certification_authority:certification_name:certification_code) EC:EPREL:123456 For Vehicles: certification(certification_authority:certification_name:certification_value) ADEME:Vehicle_CO2_Class:C If you don't include the sub-attributes in the attribute header, we’ll assume that your values include 3 sub-attributes in this order: Authority [certification_authority] Name [certification_name] Code [certification_code] If only some of your products have all sub-attributes values as required by the attribute header, you still need to use colons ( : ) as separator placeholders for the empty / non-specified sub-attribute values.
