canadian clothing canadian clothing EPA Greenhouse Gas Ratings

There are actually two scores that the EPA gives to vehicles when putting together its Green Vehicle Guide. First theres the air pollution score, which measures how substantially a cars tailpipe emissions affects local and regional air quality. Any issues such as smog, haze and other problems caused by carbon emissions are all a part of air pollution. Vehicles are scored on a scale of 1 to 10, with 1 being dirtiest and 10 being the cleanest, so its accessible and easy to understand which cars are best fit for ecofriendly driving.

Whereas the air pollution score takes into account the way your exhaust will affect nearby areas, the greenhouse gas score has a slightly broader scope in mind. It also takes into account a vehicles fuel efficiency, or essentially an estimate of how many miles per gallon a car can get during a trip in the city or down the highway.

The reason for establishing a greenhouse gas score is to take note of vehicles that can travel the same distance as another car yet burn less fuel in the process. When fuel consumption is lower, the amount of greenhouse gases emitted into the atmosphere mainly carbon dioxide, nitrous oxide and methane is also lower. Just like the air pollution score, the greenhouse gas score is based on a scale of 1 to 10, and the higher your car scores, the less your car contributes to global warming and climate change.

Carbon emissions from various fuels will vary because every fuel type burns differently. The amount of carbon released from gasoline in one mile, for instance, is not the same as the amount released from diesel or clean natural gas. The scores take into account not just petroleumbased fuels like gasoline and diesel but renewable fuels like E85. While the EPA c canadian clothing onsiders the whole lifecycle o canadian clothing f fuels, including the extraction, refining and distribution of products, it doesnt count vehicle manufacturing into its score. Thats one more area youll need to investigate on your own if you want a truly green car. canadian clothing
