New Rules for Vehicle CO₂ Efficiency Labels in Germany & France

Google Ads has released best practices in it’s help center for EU Energy Labeling (EPREL) and Energy Star labeling.

Key takeaways:

• EU Energy Labeling (EPREL):
  Use [certification] + [certification_code] instead of [energy_efficiency_class] (mandatory since April 2025). Google may auto-populate missing data using GTIN/MPN.
• Energy Star:
  Optional, but improves visibility in search results when declared via [certification].
