If you’re worried about your air conditioner’s quality, you might want to look at buying your own.
A new study published in the journal Environmental Science & Technology indicates that the air conditioners you buy today can be the equivalent of an expensive home improvement.
The study, led by researchers from Columbia University, the University of California, Santa Cruz, and the University at Buffalo, analyzed air quality in New York City neighborhoods between 2014 and 2016.
Their conclusion: You don’t need an air conditioning system that costs more than $200,000 to get the same level of air quality.
But what about your car?
Are those cars really so good?
To answer that question, the researchers reviewed the emissions of cars manufactured from 2011 through 2016.
According to the National Highway Traffic Safety Administration, an average car in America emits roughly 3,500 pounds of carbon dioxide per year, which is equivalent to nearly three cars.
The researchers analyzed emissions from all models, but specifically the Audi A4 and the Mercedes-Benz CLA.
Those models are among the most efficient cars on the market today, but the CLA’s emissions are also the most expensive.
According to the study, the emissions from those models are more than double the emissions emitted by a typical new car.
To put that in perspective, the EPA estimates that the average U.S. car emits only about 2,400 pounds of CO2 per year.
