Our verdict
"Tested here is the Tesla Model Y in its rear-wheel-drive version. The sustainability assessment is impressive and belies the fact that this is a 1.9 tonne SUV with a 60 kWh battery. The life-cycle calculations do not rely on the usual generic assumptions about the vehicle's production because Tesla supplied manufacturing data, which was reviewed by Green NCAP experts. The actions taken by Tesla to reduce the climate impact of vehicle and battery manufacturing are effective and help the car collect all 10 points in the Greenhouse Gas Index.
Scores well for brake and tyre abrasion due to smooth accelerator pedal tuning and extensive regenerative braking. Keeps production- and electricity-related emissions low.
Delivers low electricity consumption across most tests thanks to a highly efficient powertrain. Heating in cold weather increases the electricity demand due to a quick cabin heat-up. Records 15.2 and 12.7 kWh/100 km in the hot summer mixed on-road test and short urban trip, respectively.
Tesla decides to submit vehicle and battery manufacturing data for verification by Green NCAP, leading to the lowest greenhouse gas emissions published by Green NCAP so far. The total life cycle GHG emissions value of 95 g CO2‑eq./km is far below the lower threshold needed to score maximum points."

"The Berlin-built SUV, which Green NCAP says was Europe’s best-selling new electric car in 2025, is the first Tesla assessed with the company’s own verified manufacturing and battery data instead of generic production assumptions.
Category Score
Clean Air 9.0 out of 10
Energy Efficiency 8.9 out of 10
Greenhouse Gases 10.0 out of 10
Overall 93%, five stars
Green NCAP tested the single-motor version, which weighs 1,914 kg and carries a 62.5 kWh usable battery."
"The Model Y scored a full 10 out of 10 on the Greenhouse Gas Index after Tesla submitted its vehicle and battery production figures for Green NCAP’s experts to review, which let the assessor count the car’s assembly in Germany and the steps Tesla took to cut emissions from building it. The final figure came in well under the 110 g CO₂-eq./km needed for the maximum score.
Dr. Aleksandar Damyanov, technical manager at Green NCAP, said “Tesla is to be applauded for its transparent sharing of the data,” adding that verified manufacturer data makes the ratings more accurate than generic assumptions.
Efficient on the road and at the charger
In Green NCAP’s lab and road tests, the Model Y became one of only two cars rated “good” for both Consumption & Range and Cold Winter Performance, and it charged from 10% to 80% in under 24 minutes. Its main weakness is the lack of any bidirectional charging such as Vehicle-to-Load or Vehicle-to-Grid."
