Energy efficiency class [energy_efficiency_class], Minimum energy efficiency class [min_energy_efficiency_class], Maximum energy efficiency class [max_energy_efficiency_class]

Use the energy efficiency class [energy_efficiency_class] attribute to tell customers how your product rates on a given energy efficiency range. When using this attribute, you will also need to set a minimum energy efficiency class [min_energy_efficiency_class] value and a maximum energy efficiency class [max_energy_efficiency_class] value.

Note: This attribute is being deprecated April 2025. Use the certification [certification] attribute instead to show the EU energy efficiency class with your ads and free listings for products such as:

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

By providing the certification [certification] attribute, Google will lookup your product in the EU EPREL database and render the appropriate energy efficiency class on your Shopping ads and free listings. This feature supports all applicable products in the EU and applies the required textual or graphical rendering of the EU energy label to your product when appropriate.

You should be able to find the EPREL code easily in the QR code of the energy label on the product. If you aren't able to locate it, but you have energy efficiency information for your product that was provided by the manufacturer, you can still provide all 3 energy efficiency class [energy_efficiency_class] attributes during the transition period ending April 2025.

When to use

Optional for each product

The energy efficiency class [energy_efficiency_class], minimum energy efficiency class [min_energy_efficiency_class], and maximum energy efficiency class [max_energy_efficiency_class] attributes are optional, but you may be required to provide this information based on local laws or regulations. For example, if your products target any of the EU member states or Switzerland, consider the legal requirements on this matter defined in the national implementation acts of the EU directive 2017/1369 and any other applicable local law.

It’s strongly recommended that you submit the energy efficiency class [energy_efficiency_class], minimum energy efficiency class [min_energy_efficiency_class], and maximum energy efficiency class [max_energy_efficiency_class] attributes for applicable products. You might need provide this class for these types of products:

Minimum requirements

These are the requirements you'll need to meet to show your product. If you don't follow these requirements, we'll disapprove your product and let you know in your Merchant Center account.

• The minimum energy efficiency class value specifies the minimum (least efficient) energy efficiency class on the energy consumption scale for the product category your product belongs to, while the maximum energy efficiency class value specifies the maximum (most efficient) energy efficiency class on that scale.
  For example, for a product with an energy efficiency class "C" on a scale from "A+++" to "D", specify energy_efficiency_class=C with max_energy_efficiency_class=A+++ and min_energy_efficiency_class=D
• The energy efficiency class value you provide must be within the range of the minimum energy efficiency class value and the maximum energy efficiency class value.
  For example, if your range runs from "A" (most efficient, maximum energy efficiency class) down to "D" (least efficient, minimum energy efficiency class), the value for the energy efficiency class [energy_efficiency_class] attribute may not be "G".

Best practices

These best practices can help you go beyond the basic requirements to optimize your product data for performance.

• Submit either the unit pricing measure or energy efficiency class attribute. Do not submit both. If both attributes are present, only the energy efficiency class attribute will be shown.
