Since the start of the Industrial Revolution in the eighteenth and nineteenth centuries, our carbon footprint has only grown. What have we done in the last century to change the damage we do to our planet? The truth is that we hadn't even thought about the effects that cars, planes, buildings, factories have had on our planet. In 1975, when the Corporate Average Fuel Economy (CAFE) was first established as a response to the OPEC oil embargo which reduced the United States' dependence on foreign oil. Our planet is very fragile, just look at our ozone layer and how it has shrunk by 4-5% every decade since the "ozone hole" was discovered in 1985. Chlorine atoms in chloroflurocarbons (CFCs) they act as a catalyst, breaking down tens of thousands of ozone molecules before they are removed from the stratosphere. Future generations will have to face this arduous task. This is why it is critical to change and further expand CAFE policies and add a carbon tax on every gallon of gas in the United States. While trying to increase CAFEs is good for our planet, it's not the only solution. It only affects automakers and our dependence on crude oil. There is a direct correlation between CAFE and Carbon Tax. Cars emit kilos of CO2 for every liter of petrol we use and they are directly related, so we reduce costs by increasing efficiency. This is what England is currently doing, and why they implemented a carbon tax on gas prices per gallon, and why prices are so high. CAFE is "the sales-weighted average fuel economy, expressed in miles per gallon (mpg), of a manufacturer's fleet of passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 pounds or less, produced for sale ... middle of paper... 10.
