After Volkswagen failed the Environmental Protection Agency’s (EPA) emissions tests with a “defeat device” on more than 11 million diesel vehicles, cars with low greenhouse emissions have been on top of customers’ shopping lists. Vehicles that emit nitrous oxide gas 40 times of the EPA standard are causing major public health issues such as asthma and respiratory illness. That’s why buying salvage or totaled vehicles with low carbon footprint is a great idea. To be precise, if you look for a crashed car for sale, you can get higher fuel efficiency causing comparatively lower greenhouse gas emissions per gallon. Let's take a look at some of the cars that have the lowest carbon emissions and are fuel efficient.
