2019 ASG AWARDS: Best Environmental Performance Brand

NOTEWORTHY ASG FINDING: Tesla’s impressive battery electric lineup –  the Model S, Model X and Model 3 – earned ASG’s Best Environmental Performance Brand for the second consecutive year. As the U.S energy mix is increasingly cleaner year over year, the environmental benefits of electric vehicles and Teslas dominance in the sector continue to expand uninhibited.

As wind and solar projects continue to come online, economies of scale have driven costs per kwh down, not only reaching price parity in many regions of the U.S., but often reaching the lowest cost. According to a recent study by the University of Texas at Austin’s Energy Institute, wind energy is the lowest cost for a broad swath of the country, from the High Plains, the Midwest, Texas, and portions of the Northeast; while solar power is the cheapest technology in the Southwest, as well as parts of the eastern and northern regions of the U.S. Natural gas continues to lead some regions, but coal is out. 

All of this means that Tesla's EVs not only improve environmental performance and reduce GHG emissions today, with increasing benefits into the future, but this also means that with the continued increase in renewable energy production as a significant share of the national grid, comes new economies of scale that reduces the overall cost of clean power and directly lowers the cost to power Tesla powertrains.

The Automotive Performance Index (API) applies statistical methods to demonstrate each vehicle rating in relative comparison. For example, the vehicle that performs highest in environment performance in a given class obtains a rating score of 100. Each vehicle in its class is then compared relative to the top-performing vehicle with a rating score reflecting the statistical difference in performance outcomes. A score of 91 translates to a 9% environmental performance deficit as compared to the top-performing vehicle.  

Due to the API’s relative vehicle rating method, vehicle class divisions were identified as a critical input - these class divisions are detailed here.

While the Automotive Performance Index is indeed an exhaustive list of vehicles to trim level detail, with each vehicle assessment reporting over 200 unique data outputs (the culmination of thousands of data inputs), ASG has taken additional measures to ease the burden of sorting through all data points and all vehicle assessments. We have developed key performance categories and sorted all vehicles in each class according to Environmental Performance, Social Performance, Economic Performance and All-Around Performance. The vehicle in each class with the best score in each unique category is named the performance award winner (i.e. Best Environmental Performance Award winner). The vehicle in each class that scores highest combined scores in Environmental Performance, Social Performance and Economic Performance is named the ASG Best All-Around Performance Award winner.

One step further, we also name the Best 5 All-Around Performance Award winners in each class to provide consumers with a concise product comparison guide.
