On September 18, 2015 the United State Environmental Protection Agency issued a breach in the clean air act by the car group from Germany Volkswagen. This was after they discovered that the automaker intentionally programmed the TDI (turbocharged direct injection) diesel engine to reduce its emission output while undergoing emission testing in a laboratory. It’s emission of Nitrous oxide in the real world was around forty times higher than allowed. While in the laboratory it was under the limit. An estimated eleven million cars worldwide and around 500,000 cars in the US were affected by this programming. This was a horrible occurrence that showed how much some of these car companies don’t care about their environmental impact. Nitrous Oxides help create smog and are one contributor to the decrease in pH of acid rain making it more acidic, which is bad for life on Earth. Acid rain causes the acidification of lakes and streams it also contributes to the damage of trees and plants. All in all it’s not a good thing to increase the acidity of rain. This was a horrible incidence of betraying the trust of the buyers of those cars who thought they were efficient and environmentally friendly. After this was found out all of the cars with this kind of diesel engine were recalled causing huge losses for Volkswagen as they lost money in the investments of the cars and their stock took a drastic hit. So all in all it was a horrible idea as it hurt the environment and eventually themselves.
