The Tesla Model Y Rear-Wheel Drive has earned a top 5-star sustainability rating from Green NCAP. The vehicle achieved a high score of 93% following the company's first-ever disclosure of verified manufacturing and battery life-cycle data.
Why it matters
This rating highlights the impact of supply-chain transparency on a vehicle's overall environmental score. By sharing verified production data, the manufacturer achieved a perfect score on the Greenhouse Gas Index, setting a new benchmark for industry reporting.
The Model Y Rear-Wheel Drive earned a 10/10 Greenhouse Gas Index score based on its 95 g CO2-eq/km life-cycle carbon footprint. This 5-star certification reflects an evaluation of raw material extraction, manufacturing, vehicle operation, and end-of-life disposal.
The players
Tesla
An automotive manufacturer known for its production of electric vehicles and focus on battery technology.
Green NCAP
An independent organization that promotes the development of cars which are clean, energy-efficient, and cause as little harm to the environment as possible.
The details
Green NCAP calculates sustainability by analyzing emissions throughout the entire life cycle of a vehicle, including production and battery manufacturing. For this assessment, the manufacturer provided comprehensive data regarding battery cell production and supply-chain practices. This verified documentation allows the evaluator to more accurately determine the Greenhouse Gas Index score compared to estimates used for manufacturers that do not share such detailed data.
